accuracy / precision is needed. + Therefore, this upgrade is made, keeping the old interface for the already defined tags and allowing a double precision definition, + as well as calculating rationals with higher accuracy / precision. + This higher accuracy can be used for newly defined tags like that in EXIF/GPS. + + Refer also to the very old Bugzilla issue 2542 (#69) + + A test file

In that mode, the [Tile/Strip][ByteCounts/Offsets] + arrays are only loaded when first accessed. This can speed-up the opening + of files stored on the network when just metadata retrieval is needed. + This mode has been used for years by the GDAL library when compiled with + its embedded libtiff copy. + + To avoid potential out-of-tree code (typically codecs) that would use + the td_stripbytecount and td_stripoffset array inconditionnaly assuming they + have been loaded, those have been suffixed with _p (for protected). The + use of the new functions mentioned below is then recommended. + + Another addition of this commit is the capability of loading only the + values of the offset/bytecount of the strile of interest instead of the + whole array. This is enabled with the new 'O' (Ondemand) flag of TIFFOpen() + (which implies 'D'). That behaviour has also been used by GDAL, which hacked + into the td_stripoffset/td_stripbytecount arrays directly. The new code + added in the _TIFFFetchStrileValue() and _TIFFPartialReadStripArray() internal + functions is mostly a port of what was in GDAL GTiff driver previously. + + Related to that, the public TIFFGetStrileOffset[WithErr]() and TIFFGetStrileByteCount[WithErr]() + functions have been added to API. They are of particular interest when + using sparse files (with offset == bytecount == 0) and you want to detect + if a strile is present or not without decompressing the data, or updating + an existing sparse file. + They will also be used to enable a future enhancement where client code can entirely + skip bytecount loading in some situations + + A new test/defer_strile_loading.c test has been added to test the above + capabilities. + +2019-05-10 Even Rouault <even.rouault@spatialys.com> + + Creation: use SHORT type when possible for StripByteCounts/TileByteCounts + This follows the same logic as previous commit. + +2019-05-09 Even Rouault <even.rouault@spatialys.com> + + BigTIFF creation: write TileByteCounts/StripByteCounts tag with LONG when possible + In most situations of BigTIFF file, the tile/strip sizes are of reasonable size, + that is they fit on a 4-byte LONG. So in that case, use LONG instead of LONG8 + to save some space. For uncompressed file, it is easy to detect such situations + by checking at the TIFFTileSize64()/TIFFStripSize64() return. For compressed file, + we must take into account the fact that compression may sometimes result in + larger compressed data. So we allow this optimization only for a few select + compression times, and take a huge security margin (10x factor). We also only + apply this optimization on multi-strip files, so as to allow easy on-the-fly + growing of single-strip files whose strip size could grow above the 4GB threshold. + + This change is compatible with the BigTIFF specification. According to + https://www.awaresystems.be/imaging/tiff/bigtiff.html: + "The StripOffsets, StripByteCounts, TileOffsets, and TileByteCounts tags are + allowed to have the datatype TIFF_LONG8 in BigTIFF. Old datatypes TIFF_LONG, + and TIFF_SHORT where allowed in the TIFF 6.0 specification, are still valid in BigTIFF, too. " + On a practical point of view, this is also compatible on reading/writing of + older libtiff 4.X versions. + + The only glitch I found, which is rather minor, is when using such a BigTIFF + file with TileByteCounts/StripByteCounts written with TIFF_LONG, and updating + it with an older libtiff 4.X version with a change in the + [Tile/Strip][ByteCounts/Offsets] array. In that case the _TIFFRewriteField() + function will rewrite the directory and array with TIFF_LONG8, instead of updating + the existing array (this is an issue fixed by this commit). The file will + still be valid however, hence the minor severity of this. + +2019-05-08 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'bug2799' into 'master' + fix fax2tiff + + See merge request libtiff/libtiff!55 + +2019-05-08 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'bug_2829' into 'master' + WIN32: use tif_win32.c when building with CMake + + See merge request libtiff/libtiff!75 + +2019-05-06 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'FILESOURCE_SCENETYPE_reading' into 'master' + Reading error for FileSource and SceneType tags corrected. + + See merge request libtiff/libtiff!76 + +2019-05-06 Su Laus <sulau@freenet.de> + + Reading error for FileSource and SceneType tags corrected. + EXIF tags FILESOURCE and SCENETYPE are defined as TIFF_UNDEFINED and field_readcount==1! + There is a bug in TIFFReadDirEntryByte() preventing to read correctly type TIFF_UNDEFINED fields with field_readcount==1 + Upgrade of TIFFReadDirEntryByte() with added TIFF_UNDEFINED switch-entry allows libtiff to read those tags correctly. + +2019-04-25 Thomas Bernard <miniupnp@free.fr> + + WIN32: use tif_win32.c when building with CMake. + see http://bugzilla.maptools.org/show_bug.cgi?id=2829 + + the top CMakeLists.txt defines + win32_io and USE_WIN32_FILEIO + + WIN32_IO is defined nowhere in CMake (only in automake things) + +2019-04-25 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'gitlab_pages' into 'master' + Advertise https://libtiff.gitlab.io/libtiff/ as mirror + + See merge request libtiff/libtiff!70 + +2019-04-25 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'bug_2844' into 'master' + tiff2ps.c: PSDataColorContig(): avoid heap buffer overrun + + See merge request libtiff/libtiff!69 + +2019-04-25 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'issue_2785' into 'master' + tiff2pdf.c: don't call t2p_tile_collapse_left() for Ycbcr + + See merge request libtiff/libtiff!64 + +2019-04-11 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'fix_gdal_1439' into 'master' + TIFFWriteEncodedStrip/TIFFWriteEncodedTile: fix rewriting of LZW-compressed data + + See merge request libtiff/libtiff!74 + +2019-04-11 Even Rouault <even.rouault@spatialys.com> + + TIFFWriteEncodedStrip/TIFFWriteEncodedTile: fix rewriting of LZW-compressed data + Fixes https://github.com/OSGeo/gdal/issues/1439 + + When rewriting a LZW tile/strip whose existing size is very close to a multiple of + 1024 bytes (and larger than 8192 bytes) with compressed data that is larger, + the new data was not placed at the end of the file, causing corruption. + +2019-04-08 Even Rouault <even.rouault@spatialys.com> + + Merge branch 'bug2848' into 'master' + tif_luv.c: LogLuvSetupEncode() error must return 0 + + See merge request libtiff/libtiff!72 + +2019-04-03 Thomas Bernard <miniupnp@free.fr> + + build/gitlab-ci: fix typo. + + show test-suite.log in gitlab-ci. + useful when build fails + + Add output check for tiff2ps. + note : the reference files have been generated in master branch + +2019-03-23 Even Rouault <even.rouault@spatialys.com> + + tif_read.c: potentially fix false positive from Coverity Scan.

Hence, following scenarios might happen + and trigger the NULL pointer dereference: + + (1) TIFF File of photometric type 4 or more has illegal Transfer + Function field. + + (2) TIFF File has photometric type 3 or less and defines a + SamplesPerPixel field such that SamplesPerPixel > Color Channels + without defining all extra samples in the ExtraSamples fields. + + In this patch, we address both issues with respect of the following + principles: + + (A) In the case of (1), the defined transfer table should be printed + safely even if it isn't 'legal'. This allows us to avoid expensive + checks in TIFFPrintDirectory. Also, it is quite possible that + an alternative photometric type would be developed (not part of the + standard) and would allow definition of Transfer Table. We want + libtiff to be able to handle this scenario out of the box. + + (B) In the case of (2), the transfer table should be printed at its + right size, that is if TIFF file has photometric type Palette + then the transfer table should have one row and not three, even + if two extra samples are declared. + + In order to fulfill (A) we simply add a new 'i < 3' end condition to + the broken TIFFPrintDirectory loop. This makes sure that in any case + where (b) would be respected but not (a), everything stays fine. + + (B) is fulfilled by the loop condition + 'i < td->td_samplesperpixel - td->td_extrasamples'. This is enough as + long as (b) is respected. + + Naturally, we also make sure (b) is respected.

This is not required by the TIFF standards. + + We than read the transfer function for every page. Depending on the + transfer function, we allocate either 2 or 4 bytes to the XREF buffer. + We allocate this memory after we read in the transfer function for the + page. + + For the first exploit - POC1, this file has 3 pages. For the first page + we allocate 2 extra extra XREF entries. Then for the next page 2 more + entries. Then for the last page the transfer function changes and we + allocate 4 more entries. + + When we read the file into memory, we assume we have 4 bytes extra for + each and every page (as per the last transfer function we read). Which + is not correct, we only have 2 bytes extra for the first 2 pages. As a + result, we end up writing past the end of the buffer. + + There are also some related issues that this also fixes. For example, + TIFFGetField can return uninitialized pointer values, and the logic to + detect a N=3 vs N=1 transfer function seemed rather strange. + + It is also strange that we declare the transfer functions to be of type + float, when the standard says they are unsigned 16 bit values. This is + fixed in another patch. + + This patch will check to ensure that the N value for every transfer + function is the same for every page. If this changes, we abort with an + error. In theory, we should perhaps check that the transfer function + itself is identical for every page, however we don't do that due to the + confusion of the type of the data in the transfer function. + +2017-12-10 Even Rouault <even.rouault@mines-paris.org> + + Merge branch 'undef-warn-fixes' into 'master' + Fix a couple of harmless but annoying -Wundef warnings + + See merge request libtiff/libtiff!8 + +2017-12-07 Vadim Zeitlin <vadim@zeitlins.org> + + Remove tests for undefined SIZEOF_VOIDP. + As configure never uses AC_CHECK_SIZEOF(void*), this symbol is never + defined and so it doesn't make sense to test it in the code, this just + results in -Wundef warnings if they're enabled. + + Avoid harmless -Wundef warnings for __clang_major__ + Check that we're using Clang before checking its version. + +2017-12-02 Even Rouault <even.rouault@mines-paris.org> + + Merge branch 'remove_autogenerated_files' into 'master' + Remove autogenerated files + + See merge request libtiff/libtiff!5 + +2017-12-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us> + + Merge branch 'tif_config_h_includes' into 'master' + 'tif_config.h' or 'tiffiop.h' must be included before any system header. + + See merge request libtiff/libtiff!6 + +2017-12-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us> + + 'tif_config.h' or 'tiffio.h' must be included before any system header. + +2017-12-01 Even Rouault <even.rouault@spatialys.com> + + .gitignore: add patterns for build from root. + + Remove remaining .cvsignore files. + + Remove autoconf/automake generated files, and add them to .gitignore. + +2017-12-01 Olivier Paquet <olivier.paquet@gmail.com> + + Merge branch 'makedistcheck' into 'master' + build/gitlab-ci and build/travis-ci: add a 'make dist' step in autoconf_build()… + + See merge request libtiff/libtiff!4 + +2017-12-01 Even Rouault <even.rouault@spatialys.com> + + build/gitlab-ci and build/travis-ci: add a 'make dist' step in autoconf_build() target, to check we are release-ready + +2017-12-01 Even Rouault <even.rouault@mines-paris.org> + + Merge branch 'git_updates' into 'master' + CVS to Git updates + + See merge request libtiff/libtiff!2 + +2017-12-01 Even Rouault <even.rouault@spatialys.com> + + HOWTO-RELEASE: update to use signed tags. + + README.md: use markdown syntax for hyperlinks. + +2017-11-30 Even Rouault <even.rouault@spatialys.com> + + Add .gitignore. + + Regenerate autoconf files. + + Makefile.am: update to reflect removal of README.vms and README -> README.md + + Remove all $Id and $Headers comments with CVS versions. + + HOWTO-RELEASE: update for git. + + Remove outdated .cvsignore. + + Remove outdated commit script. + + Remove README.vms. + + Rename README as README.md, and update content. + + html/index.html: reflect change from CVS to gitlab. + +2017-11-30 Olivier Paquet <olivier.paquet@gmail.com> + + Merge branch 'test-ci' into 'master' + Update CI configuration + + See merge request libtiff/libtiff!1 + +2017-11-23 Roger Leigh <rleigh@codelibre.net> + + appveyor: Correct path for git clone and skip artefact archival. + +2017-11-22 Roger Leigh <rleigh@codelibre.net> + + travis-ci: Remove unused matrix exclusion. + + Add gitlab-ci build support. + +2017-11-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us> + + * configure.ac: libtiff 4.0.9 released. + + * html/v4.0.9.html: Add HTML file to document changes in libtiff + v4.0.9. + +2017-11-17 Even Rouault <even.rouault at spatialys.com> + + * libtiff/tif_aux.c, tif_getimage.c, tif_read.c: typo fixes in + comments. + +2017-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us> + + * test/Makefile.am: Add some tests for tiff2bw. + +2017-11-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us> + + * tools/tiff2bw.c (main): Free memory allocated in the tiff2bw + program.

For example this will probably fail: + tiffcp -c none jpeg_encoded_file.tif output.tif + The reason is that when the input file contains JPEG data, + the tiffcp code forces conversion to RGB space.

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> + + * libtiff/tiffio.h: Changed "#if LOGLUV_PUBLIC" to + "#ifdef LOGLUV_PUBLIC" so it will work with VisualAge on AIX. + + http://bugzilla.remotesensing.org/show_bug.cgi?id=39 + +2001-03-16 Frank Warmerdam <warmerdam@pobox.com> + + * tif_dirinfo.c: moved definition of copyright tag in field list. + Apparently they have to be in sorted order by tag id. + +2001-03-13 Frank Warmerdam <warmerdam@pobox.com> + + * tif_getimage.c: Added support for 16bit minisblack/miniswhite + images in RGBA interface. + +2001-03-02 Frank Warmerdam <warmerdam@pobox.com> + + * Added TIFFTAG_COPYRIGHT support. + +2001-02-19 Frank Warmerdam <warmerdam@pobox.com> + + * Brent Roman contributed updated tiffcp utility (and tiffcp.1) + with support for extracting subimages with the ,n syntax, and also + adding the -b bias removal flag. + +2001-02-16 Frank Warmerdam <warmerdam@pobox.com> + + * libtiff/libtiff.def: Brent Roman submitted new version adding + several missing entry points. + + * 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> + + * Makefile.in: Now cleaning up after itself after creating the .tar.gz and .zip + +2001-01-07 Frank Warmerdam <warmerdam@pobox.com> + + * html/libtiff.html: Fixed arguments in example for TIFFRGBAImageGet() + as per bug report by Patrick Connor. + +2000-12-28 Frank Warmerdam <warmerdam@pobox.com> + + * Added RELEASE-DATE file to release file list. + + * Fixed libtiff/makefile.vc to make tiffvers.h not version.h. + +2000-12-22 Mike Welles <mike@bangstate.com> + * added link to CVS mirror from index.html + + * updated html/internals.html to note that LZW compression is + not supported by default. + +2000-12-22 Frank Warmerdam <warmerdam@pobox.com> + + * updated html/libtiff.html to not point at Niles' old JPL web site + for the man pages, point at www.libtiff.org. + +2000-12-21 Frank Warmerdam <warmerdam@pobox.com> + + * libtiff/tif_apple.c: Applied "Carbon" support patches supplied by + Leonard Rosenthol <leonardr@lazerware.com>.

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. + */ + +#include <math.h> +#include <stdio.h> +#include <stdlib.h> + +/* + * State block for each open TIFF + * file using LogLuv compression/decompression. + */ +typedef struct logLuvState LogLuvState;

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. Although there is currently no define or + other configuration mechanism to disable this behavior, 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 consistently 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 disadvantage 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. +*/ + +#define WIN32_LEAN_AND_MEAN +#define VC_EXTRALEAN + +#include "tiffiop.h" +#ifdef OJPEG_SUPPORT + +/* Configuration defines here are: + * JPEG_ENCAP_EXTERNAL: The normal way to call libjpeg, uses longjump.
