-
- * libtiff 3.9.5 released.
-
-2011-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * configure.ac: Should use AC_CANONICAL_HOST since host specifies
- the run-time target whereas target is used to specify the final
- output target if the package is a build tool (like a compiler),
- which libtiff is not. Resolves libtiff bug 2307 "Use
- AC_CANONICAL_HOST macro".
-
-2011-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since
- it is much more portable. Tmpfile is included in ISO/IEC
- 9899:1990 and the WIN32 CRT.

-
- * libtiff/tiffiop.h: avoid declaring int64/uint64 on AIX with XLC
- where they are already available. (#2301)
-
- * libtiff/tif_thunder.c: Correct potential buffer overflow with
- thunder encoded files with wrong bitspersample set. The libtiff
- development team would like to thank Marin Barbella and TippingPoint's
- Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004,
- CVE-2011-1167).

- * libtiff/tif_fax3.h: Fix to last change allowing zero length
- runs at the start of a scanline - needed for legal cases.
-
-2011-03-02 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
- a move left. Without this, a malicious input file can generate an
- indefinitely large series of runs without a0 ever reaching the right
- margin, thus overrunning our buffer of run lengths. Per CVE-2011-0192.
- This is a modified version of a patch proposed by Drew Yao of Apple
- Product Security. It adds an unexpected() report, and disallows the
- equality case, since emitting a run without increasing a0 still allows
- buffer overrun.

-
- * tools/tiffset.c: Properly handle TIFFTAG_PAGENUMBER,
- TIFFTAG_HALFTONEHINTS, TIFFTAG_YCBCRSUBSAMPLING, TIFFTAG_DOTRANGE
- which should be set by value.
-
- * libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag()
- and _TIFFFieldWithName() if the tag is not found in the tag table.
- This should be normal situation and returned NULL value should be
- properly handled by the caller.
-
- * libtiff/{tif_dirwrite.c, tif_print.c}: Properly handle "DotRange"
- tag as it can be either byte or short size and should be set and read
- by value, not as an array. As per bug
- http://bugzilla.maptools.org/show_bug.cgi?id=2116
-
-2010-07-02 Andrey Kiselev <dron@ak4719.spb.edu>

-
- * libtiff/tif_dir.c: Set the bogus post-decoding hook when processing
- TIFFTAG_BITSPERSAMPLE in _TIFFVSetField() for the case of 8 bit when
- we don't need any post-processing. That helps to reset the hook if we
- previously set this field to some other value and the hook was
- initialized accordingly. As per bug
- http://bugzilla.maptools.org/show_bug.cgi?id=2035
-
-2010-06-30 Andrey Kiselev <dron@ak4719.spb.edu>
-

- definated late by a codec (#2210)
-
- * libtiff/tif_dirread.c: Fixed inadequate validation of the
- SubjectDistance field (#2212).
-
- * tiff2pdf.c: Fix assorted bugs in tiff2pdf: missing "return"
- in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
- wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
- size is larger. Also, there are a bunch of places that try to
- memset() a malloc'd buffer before checking for malloc failure, which
- would result in core dump if there actually were a failure. (#2211)
-
-2010-06-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * tools/tiff2rgba.c: Applied portion of patch (from Tom Lane)

- libtiff: integer overflows in various inter-color space conversion
- tools". http://bugzilla.maptools.org/show_bug.cgi?id=2079
-
- * libtiff/tiffiop.h (TIFFSafeMultiply): Need more castings to
- avoid compiler warnings if parameter types are not sign
- consistent.
-
- * tools/tiffcrop.c: Applied patch from Richard Nolde: Corrected
- European page size dimensions. Added an option to allow the user
- to specify a custom page size on the command line. Fix the case
- where a page size specified with a fractional part was being
- coerced to an integer by retyping the variables that define the
- paper size.
-
- * libtiff 3.9.3 released.
-
- * tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject
- YCbCr subsampled data since tiffcp currently doesn't support it.
- http://bugzilla.maptools.org/show_bug.cgi?id=2097

-
-2010-06-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * libtiff/tif_dir.h: Restore ReferenceBlackWhite as a non-custom
- field. This avoids a multi-thread reentrancy problem as well as
- fixing output of wrong tag value due to redundant definitions for
- the same tag in the tiffFieldInfo[] array. Resolves
- http://bugzilla.maptools.org/show_bug.cgi?id=2185
-
- * libtiff/tif_fax3.c (Fax3SetupState): Yesterday's fix for
- CVE-2010-1411 was not complete.
-
- * libtiff/tiffiop.h (TIFFSafeMultiply): New macro to safely
- multiply two integers. Returns zero if there is an integer
- overflow.
-
- * tools/tiffcp.c (main): Fix more TIFF handle leaks.
-
- * libtiff/tif_read.c (TIFFReadBufferSetup): Skip allocating
- tif_rawdata if tif_rawdatasize becomes zero.

-2010-06-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * tools/tiffcrop.c: Removed duplicated macros such as
- TIFFhowmany().
-
- * Update libtool to version 2.2.8.
-
- * libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of
- buffer due to integer overflow in TIFFroundup() and several other
- potential overflows. In conjunction with the fix to TIFFhowmany(),
- fixes CVE-2010-1411.
-
- * libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
- result in an integer overflow. This causes TIFFroundup() to also
- return zero if there would be an integer overflow.
-
- * libtiff/tif_read.c (TIFFReadBufferSetup): Return an error if
- tif_rawdatasize becomes zero due to an initial raw size of zero or
- an overflow reported by TIFFroundup().
-
- * libtiff/tif_ojpeg.c (OJPEGReadBufferFill): Report an error and
- avoid a crash if the input file is so broken that the strip
- offsets are not defined.
-
- * tools/tiffcp.c (main): tiffcp should not leak memory if an error
- is reported when reading the input file.
-
- * libtiff/tif_aux.c (_TIFFCheckRealloc): Produce a fully detailed
- error message string.
-
- * Add an emacs formatting mode footer to all source files so that
- emacs can be effectively used.
-
-2010-06-03 Oliver Chen Feng <scip8183@gmail.com>
-
- * libtiff/tools/tiffcp.c: add a new option -x to force merged tiff
- file PAGENUMBER value in sequence for users who care the page
- sequence, this will also prevent tiff2pdf from creating pdf file from
- the merged tiff file with wrong page sequence.
-
-2010-05-07 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: Ensure that quality is always set in
- JPEGPreEncode(), not just when we want to output local tables.
- Otherwise the quality used during compression may not be right and
- might not match the tables in the tables tag. This bug only occurs
- when seeking between directories in the midst of writing blocks.
- http://trac.osgeo.org/gdal/ticket/3539
-
-2010-05-05 Olivier Paquet <olivier.paquet@gmail.com>
-
- * libtiff/tif_print.c: Have TIFFTAG_REFERENCEBLACKWHITE always print 6
- floats instead of 2*SamplesPerPixel.
- http://bugzilla.maptools.org/show_bug.cgi?id=2186
- * man/TIFFGetField.3tiff, man/TIFFSetField.3tiff: Fixed doc to reflect the
- fact that libtiff considers TIFFTAG_REFERENCEBLACKWHITE to be 6 floats.
-
-2010-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

-
- * libtiff/tif_jpeg.c: Do not generate a JPEGTables tag when creating
- the JPEG TIFF as is is not required in order to prevent it from
- being unused and filled with invalid data. (Leave it to be
- generated by later activity.)
- http://bugzilla.maptools.org/show_bug.cgi?id=2135
- * tools/tiff2pdf.c: Write the JPEG SOI headers into the TIFF strip
- data rather than skipping them. This fixes the ability to view in
- Acrobat Reader, Evince, and Ghostscript.
- http://bugzilla.maptools.org/show_bug.cgi?id=2135
- * libtiff/tif_fax3.c: Don't return error on badly-terminated MMR

-
-2009-08-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-

- from Alexey Chupahin.
-
-2007-11-22 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for
- establishing if an existing tile can be rewritten to the same location
- by comparing the current size to all the other blocks in the same
- directory. This is dangerous in many situations and can easily
- corrupt a file. (observed in esoteric GDAL situation that's hard to
- document). This change involves leaving the stripbytecount[] values
- unaltered till TIFFAppendToStrip(). Now we only write a block back
- to the same location it used to be at if the new data is the same
- size or smaller - otherwise we move it to the end of file.
-
- * tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
- data when writing the directory just because we have BEENWRITING at
- some point in the past. This was causing odd junk to be written out
- in a tile of data when a single tile had an interleaving of reading
- and writing with reading last. (highlighted by gdal
- autotest/gcore/tif_write.py test 7.
-
- * tif_predict.c: use working buffer in PredictorEncodeTile to avoid
- modifying callers buffer.

- tif_predict.c, tif_zip.c}: Finally fix bug
-
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1274
-
- by introducing _TIFFMergeFieldInfo() returning integer error status
- instead of void in case of problems with field merging (e.g., if the
- field with such a tag already registered). TIFFMergeFieldInfo() in
- public API remains void. Use _TIFFMergeFieldInfo() everywhere and
- check returned value.

-
- * contrib/addtiffo/tif_overview.c: Fix problems with odd sized output
- blocks in TIFF_DownSample_Subsampled() (bug 1542).
-
-2007-04-06 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
- will convert from decompressor to compressor or compress to decompress
- if required by the force arguments. This works around a problem in
- where the JPEGFixupTestSubsampling() may cause a decompressor to
- be setup on a directory when later a compressor is required with the
- force flag set. Occurs with the addtiffo program for instance.

-
- * libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
- (defined in tiffconf.h - 1 by default) then the RGBA interface
- will assume that a fourth extra sample is ASSOCALPHA if the
- EXTRASAMPLE value isn't set for it. This changes the behaviour of

- lots of applications that don't mark the alpha values properly.

-
- * configure, Makefile.in, etc: added support for OPTIMIZER being
- set from config.site.

-2001-03-28 Frank Warmerdam <warmerdam@pobox.com>
-
- * fax2ps.c: Helge (libtiff at oldach.net) submitted fix:
-
- Here's a fix for fax2ps that corrects behaviour for non-Letter paper
- sizes. It fixes two problems:
-
- Without scaling (-S) the fax is now centered on the page size specified
- with -H and/or -W. Before, fax2ps was using an obscure and practially
- useless algorithm to allocate the image relative to Letter sized paper
- which sometime sled to useless whitespace on the paper, while at the
- same time cutting of the faxes printable area at the opposite border.
-
- Second, scaling now preserves aspect ratio, which makes unusual faxes
- (in particular short ones) print properly.
-
- See http://bugzilla.remotesensing.org/show_bug.cgi?id=35
-
- * tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
- Bruce A. Mallett. See check message for detailed information
- on all the changes, including a faster encoder, fixes for level
- 2 PostScript, and support for the imagemask operator.
-
-2001-03-27 Frank Warmerdam <warmerdam@pobox.com>
-

- http://bugzilla.remotesensing.org/show_bug.cgi?id=39
-
-2001-03-16 Frank Warmerdam <warmerdam@pobox.com>

-
- * libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
- Some sort of weird VMS thing.
-
- http://bugzilla.remotesensing.org/show_bug.cgi?id=31
-
- * tif_luv.c/tiff.h/tiffio.h:
- New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
- (greg@shutterfly.com). He writes:
-
- 1) I improved the gamut-mapping function in tif_luv.c for imaginary
- colors, because some images were being super-saturated on the input
- side and this resulted in some strange color shifts in the output.
-
- 2) I added a psuedotag in tiff.h to control random dithering during
- LogLuv encoding. This is turned off by default for 32-bit LogLuv and
- on for 24-bit LogLuv output. Dithering improves the average color
- accuracy over the image.
-
- 3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
- tiffio.h, to expose internal routines for converting between LogLuv and
- XYZ coordinates. This is helpful for writing more efficient,
- specialized conversion routines, especially for reading LogLuv files.
-
- Changes applied with minor edits.
-
-2001-01-23 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
- whether we are encoding or decoding. This is to ensure graceful
- recovery if TIFFClientOpen() discovers an attempt to open a compressed
- file for "r+" access, and subsequently close it, as it resets the
- tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
- compressor's concept of whether it is in encode or decode mode.
-
-2001-01-08 Mike Welles <mike@bangstate.com>

- installed with the others. They are not installed by default.
-
- * libtiff/Makefile.in: Added @MACHLIBDEPS@ to LINUXdso and GNULDdso
- targets so libtiff.so will be built with an explicit dependency
- on libm.so.
-
- * libtiff/Makefile.in: Use softlinks to link libtiff.so.3 to
- libtiff.so.3.5.5.
-
- * libtiff/Makefile.in & configure: Remove all references to the ALPHA
- file, or ALPHA version logic. Added stuff about DIST_POINT in
- place of DIST_TYPE and the alpha release number stuff.
-
-2000-11-22 Frank Warmerdam <warmerdam@pobox.com>
-
- * I have applied a patch from Steffen Moeller <moeller@ebi.ac.uk> to
- the configure script so that it now accepts the --prefix, and
- --exec-prefix directives.
-
-2000-11-13 Frank Warmerdam <warmerda@cs46980-c>
-
- * I have made a variety of modifications in an effort to ensure the
- TIFFLIB_VERSION macro is automatically generated from the RELEASE-DATE
- file which seems to be updated regularly.
-
- o mkversion.c now reads RELEASE-DATE and emits TIFFLIB_VERSION in
- version include file.
- o renamed version.h to tiffvers.h because we now have to install it
- with the public libtiff include files.
- o include tiffvers.h in tiffio.h.

-
-2000-10-19 Frank Warmerdam <warmerda@cs46980-c>
-
- * tools/rgb2ycbcr.c: fixed output strip size to account for vertical

-
-2000-09-30 Frank Warmerdam <warmerda@cs46980-c>
-
- * Modified TIFFClientOpen() to emit an error on an attempt to
- open a comperessed file for update (O_RDWR/r+) access. This is
- because the compressor/decompressor code gets very confused when
- the mode is O_RDWR, assuming this means writing only. See
- bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
-
-2000-09-27 Frank Warmerdam <warmerda@cs46980-c>

-Low-level file handling
-~~~~~~~~~~~~~~~~~~~~~~~
-The functions in osfcn.h are unavailable when compiling under C, as it's a
-C++ header. Therefore they have been implemented here.
-
-Now, why have I done it this way?
-
-The definitive API library for RISC OS is Jonathan Coxhead's OSLib, which
-uses heavily optimised ARM assembler or even plain inline SWI calls for
-maximum performance and minimum runtime size. However, I don't want to make
-LIBTIFF need that to survive. Therefore I have also emulated the functions
-using macros to _swi() and _swix() defined in the swis.h header, and
-borrowing types from kernel.h, which is less efficient but doesn't need any
-third-party libraries.

- * Some JPEG-in-TIFF produces do not emit the YCBCRSUBSAMPLING values in
- * the TIFF tags, but still use non-default (2,2) values within the jpeg
- * data stream itself. In order for TIFF applications to work properly
- * - for instance to get the strip buffer size right - it is imperative
- * that the subsampling be available before we start reading the image
- * data normally. This function will attempt to load the first strip in
- * order to get the sampling values from the jpeg data stream. Various
- * hacks are various places are done to ensure this function gets called
- * before the td_ycbcrsubsampling values are used from the directory structure,
- * including calling TIFFGetField() for the YCBCRSUBSAMPLING field from
- * TIFFStripSize(), and the printing code in tif_print.c.
- *
- * Note that JPEGPreDeocode() will produce a fairly loud warning when the
- * discovered sampling does not match the default sampling (2,2) or whatever
- * was actually in the tiff tags.
- *
- * Problems:
- * o This code will cause one whole strip/tile of compressed data to be
- * loaded just to get the tags right, even if the imagery is never read.
- * It would be more efficient to just load a bit of the header, and
- * initialize things from that.

-/*
- * TIFF Library.
- * LogLuv compression support for high dynamic range images.
- *
- * Contributed by Greg Larson.
- *
- * LogLuv image support uses the TIFF library to store 16 or 10-bit
- * log luminance values with 8 bits each of u and v or a 14-bit index.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit integer values. A 16-bit luminance is interpreted
- * as a sign bit followed by a 15-bit integer that is converted
- * to and from a linear magnitude using the transformation:
- *
- * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit
- *
- * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real
- *
- * The actual conversion to world luminance units in candelas per sq. meter
- * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
- * This value is usually set such that a reasonable exposure comes from
- * clamping decoded luminances above 1 to 1 in the displayed image.
- *
- * The 16-bit values for u and v may be converted to real values by dividing
- * each by 32768. (This allows for negative values, which aren't useful as
- * far as we know, but are left in case of future improvements in human
- * color vision.)
- *
- * Conversion from (u,v), which is actually the CIE (u',v') system for
- * you color scientists, is accomplished by the following transformation:
- *
- * u = 4*x / (-2*x + 12*y + 3)
- * v = 9*y / (-2*x + 12*y + 3)
- *
- * x = 9*u / (6*u - 16*v + 12)
- * y = 4*v / (6*u - 16*v + 12)
- *
- * This process is greatly simplified by passing 32-bit IEEE floats
- * for each of three CIE XYZ coordinates. The codec then takes care
- * of conversion to and from LogLuv, though the application is still
- * responsible for interpreting the TIFFTAG_STONITS calibration factor.
- *
- * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
- * point of (x,y)=(1/3,1/3). However, most color systems assume some other
- * white point, such as D65, and an absolute color conversion to XYZ then
- * to another color space with a different white point may introduce an
- * unwanted color cast to the image. It is often desirable, therefore, to
- * perform a white point conversion that maps the input white to [1 1 1]
- * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
- * tag value. A decoder that demands absolute color calibration may use
- * this white point tag to get back the original colors, but usually it
- * will be ignored and the new white point will be used instead that
- * matches the output color space.
- *
- * Pixel information is compressed into one of two basic encodings, depending
- * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
- * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is
- * stored as:
- *
- * 1 15
- * |-+---------------|
- *
- * COMPRESSION_SGILOG color data is stored as:
- *
- * 1 15 8 8
- * |-+---------------|--------+--------|
- * S Le ue ve
- *
- * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
- *
- * 10 14
- * |----------|--------------|
- * Le' Ce
- *
- * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
- * encoded as an index for optimal color resolution. The 10 log bits are
- * defined by the following conversions:
- *
- * L = 2^((Le'+.5)/64 - 12) # real from 10-bit
- *
- * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real
- *
- * The 10 bits of the smaller format may be converted into the 15 bits of
- * the larger format by multiplying by 4 and adding 13314. Obviously,
- * a smaller range of magnitudes is covered (about 5 orders of magnitude
- * instead of 38), and the lack of a sign bit means that negative luminances
- * are not allowed. (Well, they aren't allowed in the real world, either,
- * but they are useful for certain types of image processing.)
- *
- * The desired user format is controlled by the setting the internal
- * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values
- * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v
- * Raw data i/o is also possible using:
- * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel
- * In addition, the following decoding is provided for ease of display:
- * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values
- *
- * For grayscale images, we provide the following data formats:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values
- * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance
- * SGILOGDATAFMT_8BIT = 8-bit gray monitor values
- *
- * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
- * scheme by separating the logL, u and v bytes for each row and applying
- * a PackBits type of compression. Since the 24-bit encoding is not
- * adaptive, the 32-bit color format takes less space in many cases.
- *
- * Further control is provided over the conversion from higher-resolution
- * formats to final encoded values through the pseudo tag
- * TIFFTAG_SGILOGENCODE:
- * SGILOGENCODE_NODITHER = do not dither encoded values
- * SGILOGENCODE_RANDITHER = apply random dithering during encoding
- *
- * The default value of this tag is SGILOGENCODE_NODITHER for
- * COMPRESSION_SGILOG to maximize run-length encoding and
- * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
- * quantization errors into noise.

-/* What is what, and what is not?
-
- This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
- stream, if any, followed by the strile data, if any. This stream is read in
- OJPEGReadByte and related functions.
-
- It analyzes the start of this stream, until it encounters non-marker data, i.e.
- compressed image data. Some of the header markers it sees have no actual content,
- like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
- other markers do have content, and the valuable bits and pieces of information
- in these markers are saved, checking all to verify that the stream is more or
- less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
- functions.
-
- Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
- up on if we've seen no SOF marker when we're at the start of the compressed image
- data. In this case, the tables are read from JpegXxxTables tags, and the other
- bits and pieces of information is initialized to its most basic value. This is
- implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
-
- When this is complete, a good and valid JPEG header can be assembled, and this is
- passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
- the compressed image data, can be passed through unchanged. This is done in
- OJPEGWriteStream functions.
-
- LibTiff rightly expects to know the subsampling values before decompression. Just like
- in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
- tag is notoriously unreliable. To correct these tag values with the ones inside
- the JPEG stream, the first part of the input stream is pre-scanned in
- OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
- or errors, up to the point where either these values are read, or it's clear they
- aren't there. This means that some of the data is read twice, but we feel speed
- in correcting these values is important enough to warrant this sacrifice. Allthough
- there is currently no define or other configuration mechanism to disable this behaviour,
- the actual header scanning is build to robustly respond with error report if it
- should encounter an uncorrected mismatch of subsampling values. See
- OJPEGReadHeaderInfoSecStreamSof.
-
- The restart interval and restart markers are the most tricky part... The restart
- interval can be specified in a tag. It can also be set inside the input JPEG stream.
- It can be used inside the input JPEG stream. If reading from strile data, we've
- consistenly discovered the need to insert restart markers in between the different
- striles, as is also probably the most likely interpretation of the original TIFF 6.0
- specification. With all this setting of interval, and actual use of markers that is not
- predictable at the time of valid JPEG header assembly, the restart thing may turn
- out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
- succeed in reading back what they write, which may be the reason why we've been able
- to discover ways that seem to work.
-
- Some special provision is made for planarconfig separate OJPEG files. These seem
- to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
- and plane. This may or may not be a valid JPEG configuration, we don't know and don't
- care. We want LibTiff to be able to access the planes individually, without huge
- buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
- case, that allow us to pass a single plane such that LibJpeg sees a valid
- single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
- planes, is done inside OJPEGReadSecondarySos.
-
- The benefit of the scheme is... that it works, basically. We know of no other that
- does. It works without checking software tag, or otherwise going about things in an
- OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
- with and without JpegInterchangeFormat, with and without striles, with part of
- the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
- and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
- of the data.
-
- Another nice side-effect is that a complete JPEG single valid stream is build if
- planarconfig is not separate (vast majority). We may one day use that to build
- converters to JPEG, and/or to new-style JPEG compression inside TIFF.
-
- A dissadvantage is the lack of random access to the individual striles. This is the
- reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
- Applications would do well accessing all striles in order, as this will result in
- a single sequential scan of the input stream, and no restarting of LibJpeg decoding
- session.

-/* Configuration defines here are:
- * JPEG_ENCAP_EXTERNAL: The normal way to call libjpeg, uses longjump. In some environments,
- * like eg LibTiffDelphi, this is not possible. For this reason, the actual calls to
- * libjpeg, with longjump stuff, are encapsulated in dedicated functions. When
- * JPEG_ENCAP_EXTERNAL is defined, these encapsulating functions are declared external
- * to this unit, and can be defined elsewhere to use stuff other then longjump.
- * The default mode, without JPEG_ENCAP_EXTERNAL, implements the call encapsulators
- * here, internally, with normal longjump.
- * SETJMP, LONGJMP, JMP_BUF: On some machines/environments a longjump equivalent is
- * conviniently available, but still it may be worthwhile to use _setjmp or sigsetjmp
- * in place of plain setjmp. These macros will make it easier. It is useless
- * to fiddle with these if you define JPEG_ENCAP_EXTERNAL.
- * OJPEG_BUFFER: Define the size of the desired buffer here. Should be small enough so as to guarantee
- * instant processing, optimal streaming and optimal use of processor cache, but also big
- * enough so as to not result in significant call overhead. It should be at least a few
- * bytes to accomodate some structures (this is verified in asserts), but it would not be
- * sensible to make it this small anyway, and it should be at most 64K since it is indexed
- * with uint16. We recommend 2K.
- * EGYPTIANWALK: You could also define EGYPTIANWALK here, but it is not used anywhere and has
- * absolutely no effect. That is why most people insist the EGYPTIANWALK is a bit silly.

- * vendor thinks TIFF is):
- *
- * 'l' use little-endian byte order for creating a file
- * 'b' use big-endian byte order for creating a file
- * 'L' read/write information using LSB2MSB bit order
- * 'B' read/write information using MSB2LSB bit order
- * 'H' read/write information using host bit order
- * 'M' enable use of memory-mapped files when supported
- * 'm' disable use of memory-mapped files
- * 'C' enable strip chopping support when reading
- * 'c' disable strip chopping support
- * 'h' read TIFF header only, do not load the first IFD
- *
- * The use of the 'l' and 'b' flags is strongly discouraged.
- * These flags are provided solely because numerous vendors,
- * typically on the PC, do not correctly support TIFF; they
- * only support the Intel little-endian byte order. This
- * support is not configured by default because it supports
- * the violation of the TIFF spec that says that readers *MUST*
- * support both byte orders. It is strongly recommended that
- * you not use this feature except to deal with busted apps
- * that write invalid TIFF. And even in those cases you should
- * bang on the vendors to fix their software.
- *
- * The 'L', 'B', and 'H' flags are intended for applications
- * that can optimize operations on data by using a particular
- * bit order. By default the library returns data in MSB2LSB
- * bit order for compatibiltiy with older versions of this
- * library. Returning data in the bit order of the native cpu
- * makes the most sense but also requires applications to check
- * the value of the FillOrder tag; something they probably do
- * not do right now.
- *
- * The 'M' and 'm' flags are provided because some virtual memory
- * systems exhibit poor behaviour when large images are mapped.
- * These options permit clients to control the use of memory-mapped
- * files on a per-file basis.
- *
- * The 'C' and 'c' flags are provided because the library support
- * for chopping up large strips into multiple smaller strips is not
- * application-transparent and as such can cause problems. The 'c'
- * option permits applications that only want to look at the tags,
- * for example, to get the unadulterated TIFF tag information.

- * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to
- * be the normal linear color range, in addition over 1 values are
- * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
- * The encoding is lossless for 8-bit values, slightly lossy for the
- * other bit depths. The actual color precision should be better
- * than the human eye can perceive with extra room to allow for
- * error introduced by further image computation. As with any quantized
- * color format, it is possible to perform image calculations which
- * expose the quantization error. This format should certainly be less
- * susceptable to such errors than standard 8-bit encodings, but more
- * susceptable than straight 16-bit or 32-bit encodings.
- *
- * On reading the internal format is converted to the desired output format.
- * The program can request which format it desires by setting the internal
- * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
- * PIXARLOGDATAFMT_FLOAT = provide IEEE float values.
- * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values
- * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values
- *
- * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
- * values with the difference that if there are exactly three or four channels
- * (rgb or rgba) it swaps the channel order (bgr or abgr).
- *
- * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
- * packed in 16-bit values. However no tools are supplied for interpreting
- * these values.
- *
- * "hot" (over 1.0) areas written in floating point get clamped to
- * 1.0 in the integer data types.
- *
- * When the file is closed after writing, the bit depth and sample format
- * are set always to appear as if 8-bit data has been written into it.
- * That way a naive program unaware of the particulars of the encoding
- * gets the format it is most likely able to handle.
- *
- * The codec does it's own horizontal differencing step on the coded
- * values so the libraries predictor stuff should be turned off.
- * The codec also handle byte swapping the encoded values as necessary
- * since the library does not have the information necessary
- * to know the bit depth of the raw unencoded buffer.

- * Makefile.am: Update to Automake 1.12.4
-
-2012-08-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * Makefile.in: Update to Automake 1.12.3
-
- * libtiff{tiff.h, tif_print.c, tif_dirinfo.c, tif_dirread.c}: Add
- some TIFF/FX support in libtiff. Add the tag definitions to
- tiff.h. Add the related TIFF field definitions to tif_dirinfo.c,
- and also fixes an error in a comment. Adds the photometric values
- to tif_print.c, and fixes a bug. These changes are by Steve
- Underwood.
-
-2012-08-13 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_write.c: Fix bug rewriting image tiles in a
- compressed file: http://trac.osgeo.org/gdal/ticket/4771
-
-2012-08-02 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_dirread.c: report error in case of mismatch value
- counts for tags (ie. DotRange).
-
-2012-07-26 Tom Lane <tgl@sss.pgh.pa.us>
-
- * libtiff/{tiffio.h, tif_dirinfo.c, libtiff.def}: Add six new
- functions TIFFFieldTag(), TIFFFieldName(), TIFFFieldDataType(),
- TIFFFieldPassCount(), TIFFFieldReadCount(), TIFFFieldWriteCount()
- as external accessors for the opaque type TIFFField.
-
- * tools/tiffset.c: Make tiffset use the above functions instead of
- relying on library private headers.
-
-2012-07-19 Tom Lane <tgl@sss.pgh.pa.us>
-
- * tools/tiff2pdf.c: Fix two places where t2p_error didn't get set
- after a malloc failure. No crash risk AFAICS, but the program
- might not report exit code 1 as desired. h/t mancha@mac.hush.com
-
-2012-07-18 Tom Lane <tgl@sss.pgh.pa.us>
-
- * tools/tiff2pdf.c: Fail when TIFFSetDirectory() fails. This
- prevents core dumps or perhaps even arbitrary code execution when
- processing a corrupt input file (CVE-2012-3401).
-
-2012-07-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * test/raw_decode.c (main): Test fixes to work with IJG JPEG 7+.
- IJG JPEG 7+ uses a different upsampling algorithm which produces
- different numeric results.
-
- * libtiff/tif_jpeg.c (JPEGPreDecode): Patch from Even Rouault to
- work with IJG JPEG 7+.
-
-2012-07-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * test/raw_decode.c: Add changes so that test can run with build
- directory outside of source directory.
-
-2012-07-02 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_jpeg.c: Fix handling when writing RGBA jpeg compressed
- imagery (http://trac.osgeo.org/gdal/ticket/4732)
-
-2012-06-20 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_fax3.c: fix memory initialization of runs, only
- partly done.
-
- * libtiff/tif_pixarlog.c: Make sure tbuf is large enough for one
- full "stride" past the end.
-
-2012-06-19 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_packbits.c: fix read past end of data buffer.
-
-2012-06-15 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff 4.0.2 released.
-
- * tools/tif2pdf.c, tools/tifdump.c: avoid unitialized variable
- warnings with clang.
-
-2012-06-15 Tom Lane <tgl@sss.pgh.pa.us>
-
- * tools/tiff2pdf.c: Defend against integer overflows while
- calculating required buffer sizes (CVE-2012-2113).
-
-2012-06-12 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_print.c: Be careful about printing corrupt inknames.
-
- * libtiff/tif_fax3.c: Ensure runs array is initialized to zeros.
-
-2012-06-07 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_print.c: avoid pretty printing other fields when
- we don't have the proper amount and type of data or if the field
- is actually autodefined.
-
-2012-06-05 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_tile.c, libtiff/tif_strip.c: Ensure that illegal
- ycbcrsubsampling values result in a runtime error, not just an
- assertion.
-
- * tests/custom_dir.c: Add testing of EXIF and custom directory
- reading and writing.
-
- * libtiff/tif_dir.c, libtiff/tiffio.h: Add TIFFCreateCustomDirectory()
- and TIFFCreateEXIFDirectory() functions.
-
- * libtiff/tif_dir.c, tif_print.c : Remove FIELD_CUSTOM handling for
- PAGENUMBER, HALFTONEHINTS, and YCBCRSUBSAMPLING. Implement DOTRANGE
- differently. This is to avoid using special TIFFGetField/TIFFSetField
- rules for these fields in non-image directories (like EXIF).
-
-2012-06-04 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_jpeg.c: Remove code for fixing up h_sampling and v_sampling
- in JPEGPreDecode(). If a fixup will be done it needs to be done sooner
- in JPEGFixupTagsSubsampling() or else buffer sized may be wrong.
-
-2012-06-01 Frank Warmerdam <warmerdam@google.com>
-
- * tools/tiffinfo.c: Do not try to read image data in EXIF directories.
-
- * libtiff/tif_getimage.c: added support for _SEPARATED CMYK images.
- http://bugzilla.maptools.org/show_bug.cgi?id=2379
-
- * libtiff/tif_unix.c: use strerror() to return a more specific error message
- on failed open.
- http://bugzilla.maptools.org/show_bug.cgi?id=2341
-
- * libtiff/tif_jpeg.c: Fix JPEGDecodeRaw() bugs.
- http://bugzilla.maptools.org/show_bug.cgi?id=2386
-
- * tests/decode_raw.c, tests/images/quad-tile.jpg.tiff: add limited support
- for testing jpeg in tiff image decoding including the "raw" decode interface.
-
-2012-05-31 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_jpeg.c: avoid overrunning the end of the output buffer in
- JPEGDecodeRaw() - mostly likely to occur when there is confusion about
- sampling values.
-
- * libtiff/tif_read.c: Make sure tif_rawdatasize is cleared when tif_rawdata is freed.
-
- * libtiff/tif_getimage.c: Add support for greyscale+alpha c/o Jérémie Laval.
- http://bugzilla.maptools.org/show_bug.cgi?id=2398
-
-2012-05-29 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_dir.c: avoid using specific set/get logic to process fields in custom directories,
- like EXIF directories. This fixes problems like a tag "320" existing in a custom directory getting
- processed as if it were a colormap when it isn't really. Damn the wide variety of argument formulations
- to get/set functions for different tags!
-
- * libtiff/tif_dir.c: Ensure that we keep track of when tif_rawdata
- is a pointer into an mmap()ed file via TIFF_BUFFERMMAP flag.
-
-2012-05-24 Frank Warmerdam <warmerdam@google.com>
-
- * libtiff/tif_pixarlog.c: Allocate working buffer one word larger since we "forward
- accumulate" and overwrite the end by one word in at least some cases.

-
-2011-12-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- directories instead of error out on the malloc(0) failure.
-
-2011-05-16 Frank Warmerdam <warmerdam@pobox.com>

- http://bugzilla.maptools.org/show_bug.cgi?id=2316
-
-2011-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * libtiff 4.0.0beta7 released.
-
-2011-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * configure.ac: Should use AC_CANONICAL_HOST since host specifies
- the run-time target whereas target is used to specify the final
- output target if the package is a build tool (like a compiler),
- which libtiff is not. Resolves libtiff bug 2307 "Use
- AC_CANONICAL_HOST macro".
-
-2011-04-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * configure.ac: Support configuring TIFF_INT64_FORMAT and
- TIFF_UINT64_FORMAT appropriately for MinGW32.
-
- * tools/tiffdump.c (ReadDirectory): MinGW32 needs to use WIN32
- printf conventions for 64-bit types because it uses the WIN32 CRT.
-
- * libtiff/{tif_dumpmode.c,tif_luv.c,tif_lzw.c,tif_print.c,
- tif_read.c,tif_strip.c,tif_thunder.c}: MinGW32 needs to use WIN32
- printf conventions for 64-bit types because it uses the WIN32 CRT.
-
- * tools/tiff2pdf.c (t2p_write_pdf_string): Fix printf syntax not
- understood by WIN32 CRT.
-
- * libtiff/tif_ojpeg.c: Fixes to compile with MinGW32 GCC.
-
- * tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since
- it is much more portable. Tmpfile is included in ISO/IEC
- 9899:1990 and the WIN32 CRT.
-
-2011-03-26 Frank Warmerdam <warmerdam@pobox.com>
-
- * tools/tiffset.c: add -d and -sd switches to allow operation on
- a particular directory, not just the first (jef).
-
-2011-03-21 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_thunder.c: Correct potential buffer overflow with
- thunder encoded files with wrong bitspersample set. The libtiff
- development team would like to thank Marin Barbella and TippingPoint's
- Zero Day Initiative for reporting this vulnerability (ZDI-CAN-1004,
- CVE-2011-1167).
- http://bugzilla.maptools.org/show_bug.cgi?id=2300
-
-2011-03-10 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_fax3.h: Fix to last change allowing zero length
- runs at the start of a scanline - needed for legal cases.
-
-2011-03-02 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
- a move left. Without this, a malicious input file can generate an
- indefinitely large series of runs without a0 ever reaching the right
- margin, thus overrunning our buffer of run lengths. Per CVE-2011-0192.
- This is a modified version of a patch proposed by Drew Yao of Apple
- Product Security. It adds an unexpected() report, and disallows the
- equality case, since emitting a run without increasing a0 still allows
- buffer overrun.
-
-2011-02-23 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: avoid divide by zero in degenerate case (#2296)

- configure option to enable the experimental feature from a couple
- months ago for reading big strips in chunks.
-
- * configure.ac, tif_read.c, tif_readdir.c, tif_dir.h, tiffiop.h,
- tif_write.c, tif_print.c, tif_jpeg.c, tif_dirwrite.c, tif_write.c:
- Implement optional support for deferring the load of strip/tile
- offset and size tags for optimized scanning of directories. Enabled
- with the --enable-defer-strile-load configure option (DEFER_STRILE_LOAD
- #define in tif_config.h).
-
-2011-02-11 Frank Warmerdam <warmerdam@pobox.com>

-2011-01-24 Olivier Paquet <olivier.paquet@gmail.com>
-
- * libtiff/{tif_dir.{h,c}, tif_dirinfo.c, tif_dirread.c, tif_dirwrite.c,
- tif_print.c, tiff.h, tiffiop.h} : Added support for
- TIFFTAG_SMINSAMPLEVALUE and TIFFTAG_SMAXSAMPLEVALUE to have different
- values for each sample. Presents the min/max of all samples by default for
- compatibility. TIFFSetField/TIFFGetField can be made to handle those tags
- as arrays by changing the new TIFFTAG_PERSAMPLE pseudo tag.

-
-2011-01-06 Frank Warmerdam <warmerdam@pobox.com>
-

- maintained.
-
- * libtiff/tif_zip.c: Maintain tif_rawcc/tif_rawcp when decoding
- for CHUNKY_STRIP_READ_SUPPORT.
-
- * libtiff/tif_jpeg.c: ensure that rawcc and rawcp are maintained
- during JPEGPreDecode and JPEGDecode calls.
- * libtiff/tif_read.c: larger read ahead for CHUNKY_STRIP_READ_SUPPORT,
- as compression formats like JPEG keep 16 lines interleaved in a sense
- and might need to touch quite a bit of data.

- which should be set by value.
-
- * libtiff/tif_dirinfo.c: Don't use assertions in _TIFFFieldWithTag()

-
- * libtiff/tif_dir.c: Set the bogus post-decoding hook when processing
- TIFFTAG_BITSPERSAMPLE in _TIFFVSetField() for the case of 8 bit when
- we don't need any post-processing. That helps to reset the hook if we
- previously set this field to some other value and the hook was
- initialized accordingly. As per bug
- http://bugzilla.maptools.org/show_bug.cgi?id=2035
-
-2010-07-01 Andrey Kiselev <dron@ak4719.spb.edu>

-
- * tools/tiff2pdf.c: Fixed computation of the tile buffer size when

-
- * libtiff/tif_dirinfo.c: Fix invocation of tag compare function (#2201)
-
- * tools/tiff2pdf.c: Fix assorted bugs in tiff2pdf: missing "return"
- in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
- wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
- size is larger. Also, there are a bunch of places that try to
- memset() a malloc'd buffer before checking for malloc failure, which
- would result in core dump if there actually were a failure. (#2211)
-
-2010-06-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * libtiff/tiffiop.h (TIFFSafeMultiply): Need more castings to

- * libtiff 4.0.0alpha6 released.
-
- * tools/tiffcrop.c: Applied patch from Richard Nolde: Corrected
- European page size dimensions. Added an option to allow the user
- to specify a custom page size on the command line. Fix the case
- where a page size specified with a fractional part was being
- coerced to an integer by retyping the variables that define the
- paper size.
-
- * html/index.html: Update for the 3.9.3 release.
-
- * tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject

- fixes CVE-2010-1411.
-
- * libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
- result in an integer overflow. This causes TIFFroundup() to also
- return zero if there would be an integer overflow.

-
-2010-05-08 Olivier Paquet <olivier.paquet@gmail.com>
-
- * libtiff/tif_dirread.c: Restored TIFFReadDirEntryFloat function in order

-2010-05-07 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: Ensure that quality is always set in
- JPEGPreEncode(), not just when we want to output local tables.
- Otherwise the quality used during compression may not be right and
- might not match the tables in the tables tag. This bug only occurs
- when seeking between directories in the midst of writing blocks.
- http://trac.osgeo.org/gdal/ticket/3539
-
-2010-05-06 Andrey Kiselev <dron@ak4719.spb.edu>

-
-2010-04-21 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: avoid preparing jpeg tables everytime
- JPEGSetupEncode() is called if the tables already seem to be
- established. This prevents spurious updates and rewriting of
- directories with jpegtables when doing updates to existing images.
- http://trac.osgeo.org/gdal/ticket/3539
-
-2010-04-20 Olivier Paquet <olivier.paquet@gmail.com>

- http://bugzilla.maptools.org/show_bug.cgi?id=2139
-
-2010-04-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * libtiff/tif_dir.c (_TIFFVSetField): Add a special error case for
- when the tag count value is zero. Error handling is still a
- regression since in 3.9.2, empty tags are skipped (with a warning)
- rather than returning a hard error and refusing to read the file.
-
- * tools/ppm2tiff.c (main): While case for parsing comment line
- requires extra parenthesis to work as expected. Reported by
- Thomas Sinclair.
-
-2010-04-02 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_read.c (primarily): Add support for
- CHUNKY_STRIP_READ_SUPPORT where large strips are
- read in chunks for applications using TIFFReadScanline().
- This is intended to make it more practical work with very
- large compressed one-strip files. Feature is off by default.
- Enable by defining CHUNK_STRIP_READ_SUPPORT as a macro.
- http://trac.osgeo.org/gdal/ticket/3514
-
-2010-03-31 Frank Warmerdam <warmerdam@pobox.com>

- being unused and filled with invalid data. (Leave it to be
- generated by later activity.)
- http://bugzilla.maptools.org/show_bug.cgi?id=2135
- * tools/tiff2pdf.c: Write the JPEG SOI headers into the TIFF strip
- data rather than skipping them. This fixes the ability to view in
- Acrobat Reader, Evince, and Ghostscript.
- http://bugzilla.maptools.org/show_bug.cgi?id=2135
- * libtiff/tif_fax3.c: Don't return error on badly-terminated MMR

-
-2009-12-03 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: Made JPEGDecodeRaw() check for buffer overruns.
- Made so that when working with downsampled images a stub function
- reporting an error is used for tif_decoderow. We cannot meaningfully
- support reading scanlines in this situation. (#1936)
-
- * libtiff/tif_jpeg.c: Ensure that tif_scanlinesize is computed after
- resetting of the upsampling values (gdal:#3259).
- http://bugzilla.maptools.org/show_bug.cgi?id=1936

-
- * libtiff/tif_jpeg.c: Do not try to fixup subsampling tags based on

-
- * tools/tiffset.c: Changes to reflect the fact that TIFFFieldWithTag()
- and TIFFFieldWithName() now return TIFFField pointers instead of
- TIFFFieldInfo pointers.
-
- * tools/tiffdump.c: Added ssize_t typedef on Windows since it doesn't

-
-2007-12-31 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_dirwrite.c: Added TIFFRewriteField(). This new function
- rewrites one field "on disk" updating an existing directory
- entry. Lots of limitations still...
-
- * tiffiop.h, tif_write.c, tif_dirread.c, tif_flush.c: Keep track of
- TIFF_DIRTYSTRIP separately from TIFF_DIRTYDIRECT to indicate that
- the strip offset/size values are dirty but nothing else about the
- directory is dirty. In flush handle "just stripmaps dirty" as a
- special case that just rewrites these values without otherwise
- modifying the directory on disk using TIFFRewriteField().
-
- We also modify logic so that in update mode the directory is not
- marked dirty on read, but only when something is changed. This
- means we need to keep track of updates to the stripmap stuff in
- TIFFAppendToStrip().
-
-2007-12-10 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_jpeg.c: Improve ability to switch between encoding and decoding

-2007-11-23 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_dir.c, tif_dirread.c, tif_dirwrite.c, tif_read.c, tif_write.c,
- tiffiop.h: Added TIFF_BUF4WRITE flag to indicate if contents of the
- rawcp/rawcc buffer are for writing and thus may require flushing.
- Necessary to distinguish whether they need to be written to disk when
- in mixed read/write mode and doing a mixture of writing followed by
- reading. http://trac.osgeo.org/gdal/ticket/1758
-
-2007-11-23 Andrey Kiselev <dron@ak4719.spb.edu>
-
- * configure.com, libtiff/tif_vms.c: Better OpenVMS support. Patches
- from Alexey Chupahin.
-
-2007-11-02 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for
- establishing if an existing tile can be rewritten to the same location
- by comparing the current size to all the other blocks in the same
- directory. This is dangerous in many situations and can easily
- corrupt a file. (observed in esoteric GDAL situation that's hard to
- document). This change involves leaving the stripbytecount[] values
- unaltered till TIFFAppendToStrip(). Now we only write a block back
- to the same location it used to be at if the new data is the same
- size or smaller - otherwise we move it to the end of file.
-
- * tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
- data when writing the directory just because we have BEENWRITING at
- some point in the past. This was causing odd junk to be written out
- in a tile of data when a single tile had an interleaving of reading
- and writing with reading last. (highlighted by gdal
- autotest/gcore/tif_write.py test 7.
-
- * tif_predict.c: use working buffer in PredictorEncodeTile to avoid
- modifying callers buffer.
- http://trac.osgeo.org/gdal/ticket/1965
-
- * tif_predict.c/h: more fixes related to last item, keeping a
- distinct pfunc for encode and decode cases as these were getting
- mixed up sometimes.
- http://trac.osgeo.org/gdal/ticket/1948
-
-2007-11-01 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_predict.c/h, tif_lzw.c, tif_zip.c: Improvements so that
- predictor based encoding and decoding works in read-write update
- mode properly.

- * changed some more incorrect %lud printf flags to %lu
-
-2007-09-29 Joris Van Damme <joris.at.lebbeke@skynet.be>
-
- * tif_dirread.c: Strip chopping interfered badly with uncompressed
- subsampled images because it tried to divide subsampled rowblocks,
- leading to all sorts of errors throughout the library for these
- images. Fixed by making strip chopping divide in row counts that
- are a multiple of vertical subsampling value.
-
-2007-09-28 Joris Van Damme <joris.at.lebbeke@skynet.be>
-
- * tif_dirread.c: Logical cast working around compiler warning
-
- * tif_read.c: Correction of some error flags and parameter lists
-
-2007-09-27 Joris Van Damme <joris.at.lebbeke@skynet.be>
-
- * tif_dirread.c: Made calculation of td_maxsamplevalue more robust
- when dealing with large bitspersample values, shutting up purification
- tools that warn about truncation, though it remains incorrect and
- indicates a conceptual problem there.
-
- * tif_open.c: Moved early exit in case of 'h' flag (to disable reading
- of first IFD) to proper place because it badly interfered with memory
- mapping, resulting in mapping flag even with dummy mapping functions
- that returned 0 whilst at the same time the mapping tif_size wasn't
- set, thus resulting in continuous incorrect beyond-eof errors.
-
-2007-09-24 Joris Van Damme <joris.at.lebbeke@skynet.be>
-
- * tif_dirinfo.c: Fixed (MSVC) compiler reports about
- inconsistent use of const in tiffFields and exifFields definition
-
-2007-09-20 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_dirwrite.c: Always write tile/strip offsets and sizes
- using LONG8 type when output format is BigTIFF. The
- TIFFWriteDirectoryTagLongLong8Array() function was restructured
- accordingly.
-
- * tif_dirread.c: Improvements to error reporting text in
- TIFFFetchDirectory().
-
-2007-09-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
-
- * test/images: Added a small collection of test images for use by
- test programs and scripts.
- * test/tiffinfo.sh: A trivial example test script.
- * test/common.sh: Added small script for setting the environment
- used by script-based tests.
-
-2007-08-24 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_dirwrite.c: Write the tif_nextdiroff value instead of a fixed
- zero when writing directory contents to preserve the ability to
- rewrite directories in place, even in the middle of a directory
- chain.
-
- * tif_dirinfo.c: _TIFFMergeFields() now only merges in field
- definitions that are missing. Existing definitions are silently
- ignored.
-
- * tif_dirread.c: Add runtime error for fields for which no definition
- is found (in addition to an assert for developers) in
- TIFFFetchNormalTag(). Not sure if this is needed, but it seems
- prudent.
-
-2007-08-10 Joris Van Damme <joris.at.lebbeke@skynet.be>

- tif_ojpeg.c, tif_print.c, tif_fax3.c, tif_dirread.c}: More work on new
- tag extending scheme. Use the new scheme everywhere.
-
- * libtiff/{tif_zip.c, tif_predict.c, tif_pixarlog.c, tif_luv.c,
- tif_fax3.c, tif_dirread.c, tif_dirwrite.c, tif_close.c, tif_ojpeg.c,

- TIFFReassignTagToIgnore() function and TIFFIgnoreSense enumeration
- removed.
-
- * libtiff/{tif_dirinfo.c, tif_fax3.c, tif_jbig.c, tif_jpeg.c}: Move
- tags TIFFTAG_FAXRECVPARAMS, TIFFTAG_FAXSUBADDRESS,
- TIFFTAG_FAXRECVTIME and TIFFTAG_FAXDCS to the common tag directory.
- These tags are not codec-specific and relate to image content, so
- process them as other normal tags.
-
- * libtiff/{tiffio.h, tif_dir.h}: TIFFTagValue structure moved from the
- public tiffio.h to private tif_dir.h.
-
- * contrib/{acorn, mac-cw, mac-mpw}: Removed as unmaintained and

- tif_fax3.c, tif_jbig.c, tif_luv.c, tif_ojpeg.c, tif_pixarlog.c,
- tif_predict.c, tif_zip.c}: Finally fix bug
-
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1274
-
- by introducing _TIFFMergeFieldInfo() returning integer error status
- instead of void in case of problems with field merging (e.g., if the
- field with such a tag already registered). TIFFMergeFieldInfo() in
- public API remains void. Use _TIFFMergeFieldInfo() everywhere and
- check returned value.
-
-2007-04-07 Frank Warmerdam <warmerdam@pobox.com>
-
- * contrib/addtiffo/tif_overview.c: Fix problems with odd sized output
- blocks in TIFF_DownSample_Subsampled() (bug 1542).
-
-2007-04-06 Frank Warmerdam <warmerdam@pobox.com>
-
- * libtiff/tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
- will convert from decompressor to compressor or compress to decompress
- if required by the force arguments. This works around a problem in
- where the JPEGFixupTestSubsampling() may cause a decompressor to
- be setup on a directory when later a compressor is required with the
- force flag set. Occurs with the addtiffo program for instance.

-
- * configure.ac, configure, aclocal.m4, libtiff/{mkspans.c, tif_fax3.c,
- tif_getimage.c, tif_luv.c, tif_lzw.c, tif_ojpeg.c, tif_packbits.c,

- this causes failure to build on systems which properly respect
- this request.
-
- * libtiff/tiffconf.h.in: New file to act as the template for the
- configured tiffconf.h
-
- * libtiff/files.lst (HDRS): Install the configured tiffconf.h.

-
- * libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
- (defined in tiffconf.h - 1 by default) then the RGBA interface
- will assume that a fourth extra sample is ASSOCALPHA if the

-
- * fax2ps.c: Helge (libtiff at oldach.net) submitted fix:
-
- Here's a fix for fax2ps that corrects behaviour for non-Letter paper
- sizes. It fixes two problems:
-
- Without scaling (-S) the fax is now centered on the page size specified
- with -H and/or -W. Before, fax2ps was using an obscure and practially
- useless algorithm to allocate the image relative to Letter sized paper
- which sometime sled to useless whitespace on the paper, while at the
- same time cutting of the faxes printable area at the opposite border.
-
- Second, scaling now preserves aspect ratio, which makes unusual faxes
- (in particular short ones) print properly.
-
- See http://bugzilla.remotesensing.org/show_bug.cgi?id=35
-
- * tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
- Bruce A. Mallett. See check message for detailed information

-
- * libtiff/libtiff.def: Brent Roman submitted new version adding

-
- http://bugzilla.remotesensing.org/show_bug.cgi?id=31
-
- * tif_luv.c/tiff.h/tiffio.h:
- New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
- (greg@shutterfly.com). He writes:
-
- 1) I improved the gamut-mapping function in tif_luv.c for imaginary
- colors, because some images were being super-saturated on the input
- side and this resulted in some strange color shifts in the output.
-
- 2) I added a psuedotag in tiff.h to control random dithering during
- LogLuv encoding. This is turned off by default for 32-bit LogLuv and
- on for 24-bit LogLuv output. Dithering improves the average color
- accuracy over the image.
-
- 3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
- tiffio.h, to expose internal routines for converting between LogLuv and
- XYZ coordinates. This is helpful for writing more efficient,
- specialized conversion routines, especially for reading LogLuv files.
-
- Changes applied with minor edits.
-
-2001-01-23 Frank Warmerdam <warmerdam@pobox.com>
-
- * tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
- whether we are encoding or decoding. This is to ensure graceful
- recovery if TIFFClientOpen() discovers an attempt to open a compressed
- file for "r+" access, and subsequently close it, as it resets the
- tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
- compressor's concept of whether it is in encode or decode mode.
-
-2001-01-08 Mike Welles <mike@bangstate.com>

- libtiff.so.3.5.5.
-

-
- * Modified TIFFClientOpen() to emit an error on an attempt to
- open a comperessed file for update (O_RDWR/r+) access. This is
- because the compressor/decompressor code gets very confused when
- the mode is O_RDWR, assuming this means writing only. See

- * Finally, note that we must handle remaindered data at the end
- * of a strip specially. The coder asks for a fixed number of
- * bits when scanning for the next code. This may be more bits

- * TIFF Library.
- * LogLuv compression support for high dynamic range images.
- *
- * Contributed by Greg Larson.
- *
- * LogLuv image support uses the TIFF library to store 16 or 10-bit
- * log luminance values with 8 bits each of u and v or a 14-bit index.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit integer values. A 16-bit luminance is interpreted
- * as a sign bit followed by a 15-bit integer that is converted
- * to and from a linear magnitude using the transformation:
- *
- * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit
- *
- * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real
- *
- * The actual conversion to world luminance units in candelas per sq. meter
- * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
- * This value is usually set such that a reasonable exposure comes from
- * clamping decoded luminances above 1 to 1 in the displayed image.
- *
- * The 16-bit values for u and v may be converted to real values by dividing
- * each by 32768. (This allows for negative values, which aren't useful as
- * far as we know, but are left in case of future improvements in human
- * color vision.)
- *
- * Conversion from (u,v), which is actually the CIE (u',v') system for
- * you color scientists, is accomplished by the following transformation:
- *
- * u = 4*x / (-2*x + 12*y + 3)
- * v = 9*y / (-2*x + 12*y + 3)
- *
- * x = 9*u / (6*u - 16*v + 12)
- * y = 4*v / (6*u - 16*v + 12)
- *
- * This process is greatly simplified by passing 32-bit IEEE floats
- * for each of three CIE XYZ coordinates. The codec then takes care
- * of conversion to and from LogLuv, though the application is still
- * responsible for interpreting the TIFFTAG_STONITS calibration factor.
- *
- * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
- * point of (x,y)=(1/3,1/3). However, most color systems assume some other
- * white point, such as D65, and an absolute color conversion to XYZ then
- * to another color space with a different white point may introduce an
- * unwanted color cast to the image. It is often desirable, therefore, to
- * perform a white point conversion that maps the input white to [1 1 1]
- * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
- * tag value. A decoder that demands absolute color calibration may use
- * this white point tag to get back the original colors, but usually it
- * will be ignored and the new white point will be used instead that
- * matches the output color space.
- *
- * Pixel information is compressed into one of two basic encodings, depending
- * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
- * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is
- * stored as:
- *
- * 1 15
- * |-+---------------|
- *
- * COMPRESSION_SGILOG color data is stored as:
- *
- * 1 15 8 8
- * |-+---------------|--------+--------|
- * S Le ue ve
- *
- * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
- *
- * 10 14
- * |----------|--------------|
- * Le' Ce
- *
- * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
- * encoded as an index for optimal color resolution. The 10 log bits are
- * defined by the following conversions:
- *
- * L = 2^((Le'+.5)/64 - 12) # real from 10-bit
- *
- * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real
- *
- * The 10 bits of the smaller format may be converted into the 15 bits of
- * the larger format by multiplying by 4 and adding 13314. Obviously,
- * a smaller range of magnitudes is covered (about 5 orders of magnitude
- * instead of 38), and the lack of a sign bit means that negative luminances
- * are not allowed. (Well, they aren't allowed in the real world, either,
- * but they are useful for certain types of image processing.)
- *
- * The desired user format is controlled by the setting the internal
- * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values
- * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v
- * Raw data i/o is also possible using:
- * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel
- * In addition, the following decoding is provided for ease of display:
- * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values
- *
- * For grayscale images, we provide the following data formats:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values
- * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance
- * SGILOGDATAFMT_8BIT = 8-bit gray monitor values
- *
- * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
- * scheme by separating the logL, u and v bytes for each row and applying
- * a PackBits type of compression. Since the 24-bit encoding is not
- * adaptive, the 32-bit color format takes less space in many cases.
- *
- * Further control is provided over the conversion from higher-resolution
- * formats to final encoded values through the pseudo tag
- * TIFFTAG_SGILOGENCODE:
- * SGILOGENCODE_NODITHER = do not dither encoded values
- * SGILOGENCODE_RANDITHER = apply random dithering during encoding
- *
- * The default value of this tag is SGILOGENCODE_NODITHER for
- * COMPRESSION_SGILOG to maximize run-length encoding and
- * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
- * quantization errors into noise.

-/* What is what, and what is not?
-
- This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
- stream, if any, followed by the strile data, if any. This stream is read in
- OJPEGReadByte and related functions.
-
- It analyzes the start of this stream, until it encounters non-marker data, i.e.
- compressed image data. Some of the header markers it sees have no actual content,
- like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
- other markers do have content, and the valuable bits and pieces of information
- in these markers are saved, checking all to verify that the stream is more or
- less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
- functions.
-
- Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
- up on if we've seen no SOF marker when we're at the start of the compressed image
- data. In this case, the tables are read from JpegXxxTables tags, and the other
- bits and pieces of information is initialized to its most basic value. This is
- implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
-
- When this is complete, a good and valid JPEG header can be assembled, and this is
- passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
- the compressed image data, can be passed through unchanged. This is done in
- OJPEGWriteStream functions.
-
- LibTiff rightly expects to know the subsampling values before decompression. Just like
- in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
- tag is notoriously unreliable. To correct these tag values with the ones inside
- the JPEG stream, the first part of the input stream is pre-scanned in
- OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
- or errors, up to the point where either these values are read, or it's clear they
- aren't there. This means that some of the data is read twice, but we feel speed
- in correcting these values is important enough to warrant this sacrifice. Allthough
- there is currently no define or other configuration mechanism to disable this behaviour,
- the actual header scanning is build to robustly respond with error report if it
- should encounter an uncorrected mismatch of subsampling values. See
- OJPEGReadHeaderInfoSecStreamSof.
-
- The restart interval and restart markers are the most tricky part... The restart
- interval can be specified in a tag. It can also be set inside the input JPEG stream.
- It can be used inside the input JPEG stream. If reading from strile data, we've
- consistenly discovered the need to insert restart markers in between the different
- striles, as is also probably the most likely interpretation of the original TIFF 6.0
- specification. With all this setting of interval, and actual use of markers that is not
- predictable at the time of valid JPEG header assembly, the restart thing may turn
- out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
- succeed in reading back what they write, which may be the reason why we've been able
- to discover ways that seem to work.
-
- Some special provision is made for planarconfig separate OJPEG files. These seem
- to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
- and plane. This may or may not be a valid JPEG configuration, we don't know and don't
- care. We want LibTiff to be able to access the planes individually, without huge
- buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
- case, that allow us to pass a single plane such that LibJpeg sees a valid
- single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
- planes, is done inside OJPEGReadSecondarySos.
-
- The benefit of the scheme is... that it works, basically. We know of no other that
- does. It works without checking software tag, or otherwise going about things in an
- OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
- with and without JpegInterchangeFormat, with and without striles, with part of
- the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
- and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
- of the data.
-
- Another nice side-effect is that a complete JPEG single valid stream is build if
- planarconfig is not separate (vast majority). We may one day use that to build
- converters to JPEG, and/or to new-style JPEG compression inside TIFF.
-
- A dissadvantage is the lack of random access to the individual striles. This is the
- reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
- Applications would do well accessing all striles in order, as this will result in
- a single sequential scan of the input stream, and no restarting of LibJpeg decoding
- session.

- * Process library-specific flags in the open mode string.
- * The following flags may be used to control intrinsic library
- * behaviour that may or may not be desirable (usually for
- * compatibility with some application that claims to support
- * TIFF but only supports some braindead idea of what the
- * vendor thinks TIFF is):
- *
- * 'l' use little-endian byte order for creating a file
- * 'b' use big-endian byte order for creating a file
- * 'L' read/write information using LSB2MSB bit order
- * 'B' read/write information using MSB2LSB bit order
- * 'H' read/write information using host bit order
- * 'M' enable use of memory-mapped files when supported
- * 'm' disable use of memory-mapped files
- * 'C' enable strip chopping support when reading
- * 'c' disable strip chopping support
- * 'h' read TIFF header only, do not load the first IFD
- * '4' ClassicTIFF for creating a file (default)
- * '8' BigTIFF for creating a file
- *
- * The use of the 'l' and 'b' flags is strongly discouraged.
- * These flags are provided solely because numerous vendors,
- * typically on the PC, do not correctly support TIFF; they
- * only support the Intel little-endian byte order. This
- * support is not configured by default because it supports
- * the violation of the TIFF spec that says that readers *MUST*
- * support both byte orders. It is strongly recommended that
- * you not use this feature except to deal with busted apps
- * that write invalid TIFF. And even in those cases you should
- * bang on the vendors to fix their software.
- *
- * The 'L', 'B', and 'H' flags are intended for applications
- * that can optimize operations on data by using a particular
- * bit order. By default the library returns data in MSB2LSB
- * bit order for compatibiltiy with older versions of this

-/*
- * TIFF Library.
- * PixarLog Compression Support
- *
- * Contributed by Dan McCoy.
- *
- * PixarLog film support uses the TIFF library to store companded
- * 11 bit values into a tiff file, which are compressed using the
- * zip compressor.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit or 8-bit unsigned integer values.
- *
- * On writing any of the above are converted into the internal
- * 11-bit log format. In the case of 8 and 16 bit values, the
- * input is assumed to be unsigned linear color values that represent
- * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to
- * be the normal linear color range, in addition over 1 values are
- * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
- * The encoding is lossless for 8-bit values, slightly lossy for the
- * other bit depths. The actual color precision should be better
- * than the human eye can perceive with extra room to allow for
- * error introduced by further image computation. As with any quantized
- * color format, it is possible to perform image calculations which
- * expose the quantization error. This format should certainly be less
- * susceptable to such errors than standard 8-bit encodings, but more
- * susceptable than straight 16-bit or 32-bit encodings.
- *
- * On reading the internal format is converted to the desired output format.
- * The program can request which format it desires by setting the internal
- * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
- * PIXARLOGDATAFMT_FLOAT = provide IEEE float values.
- * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values
- * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values
- *
- * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
- * values with the difference that if there are exactly three or four channels
- * (rgb or rgba) it swaps the channel order (bgr or abgr).
- *
- * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
- * packed in 16-bit values. However no tools are supplied for interpreting
- * these values.
- *
- * "hot" (over 1.0) areas written in floating point get clamped to
- * 1.0 in the integer data types.
- *
- * When the file is closed after writing, the bit depth and sample format
- * are set always to appear as if 8-bit data has been written into it.
- * That way a naive program unaware of the particulars of the encoding
- * gets the format it is most likely able to handle.
- *
- * The codec does it's own horizontal differencing step on the coded
- * values so the libraries predictor stuff should be turned off.
- * The codec also handle byte swapping the encoded values as necessary
- * since the library does not have the information necessary
- * to know the bit depth of the raw unencoded buffer.
- *
- * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc.
- * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT
- * as noted in http://trac.osgeo.org/gdal/ticket/3894. FrankW - Jan'11

- The std::ios::pos_type is used to represent stream positions as used
- by tellg(), tellp(), seekg(), and seekp(). This makes it similar to
- (but perhaps not the same as) 'off_t'. The std::ios::streampos type
- is used for character streams, but is documented to not be an
- integral type anymore, so it should *not* be assigned to an integral
- type.
-
- The std::ios::off_type is used to specify relative offsets needed by
- the variants of seekg() and seekp() which accept a relative offset

-
- Set read position
- basic_istream& basic_istream::seekg(ios::pos_type)
- basic_istream& basic_istream::seekg(ios::off_type, ios_base::seekdir)
-
- Read data
- basic_istream& istream::read(char *str, streamsize count)
-
- Number of characters read in last unformatted read
- streamsize istream::gcount();
-
- Obtain write position
- ios::pos_type basic_ostream::tellp()
-
- Set write position
- basic_ostream& basic_ostream::seekp(ios::pos_type)
- basic_ostream& basic_ostream::seekp(ios::off_type, ios_base::seekdir)
