Major changes¶
Significant changes in software configuration: we are switched to GNU autotools now.
tiffset: Set any libtiff supported tags. Tags can be supplied by the mnemonic name or number.
Software configuration changes¶
Get rid of the old configuration system and switch to GNU autotools.
Library changes¶
libtiff/tif_ojpeg.c: Fixed problem with duplicatedSOIandSOFmarkers as per bug Remote Sensing bugzilla #581 [no longer available].libtiff/tif_open.c,libtiff/tiffio.h: New function added:TIFFIsBigEndian(). Function returns nonzero if given was file written in big-endian order.libtiff/tif_print.c: added (untested) support for printingSSHORT,SLONGandSRATIONALfields.libtiff/tif_fax3.c: Avoid reading CCITT compression options if compression type mismatches. See Remote Sensing bugzilla #565 [no longer available].libtiff/tif_strip.c: Never return 0 from theTIFFNumberOfStrips().libtiff/tif_dirread.c: Workaround for broken TIFF writers which store singleSampleFormatvalue for multisampled images. See Remote Sensing bugzilla #562 [no longer available].libtiff/tif_write.c: Allow in-place updating of the compressed images (don't work properly with all codecs). For details see GDAL bug Remote Sensing bugzilla #534 [no longer available].libtiff/tif_jpeg.c: Workaround for wrong sampling factors used in the Intergarph JPEG compressed TIFF images as per bug: Remote Sensing bugzilla #532 [no longer available].libtiff/tif_open.c: Use dummymmap()/munmap()functions inTIFFClientOpen()when the appropriate client functions was not supplied by user.libtiff/tif_dirread.c: Fixed problem with handlingTIFF_UNDEFINEDtag type inTIFFFetchNormalTag()as per bug Remote Sensing bugzilla #508 [no longer available].libtiff/tif_codec.c: Fixed typo inTIFFInitPackBitsname as per: Remote Sensing bugzilla #494 [no longer available].libtiff/tif_fax3.c: Fixed problem, introdiced in 3.6.1 release, with the CCITT encoding modes as per bug Remote Sensing bugzilla #483 [no longer available]. We need more work on fax codec to support update mode.libtiff/tiff.h: Fixed tag definitions forTIFFTAG_YCLIPPATHUNITSandTIFFTAG_INDEXEDas per bug Remote Sensing bugzilla #475 [no longer available].libtiff/tif_win32.c,libtiff/tif_unix.c: Check whether the pointer isNULLbefore proceeding further as per bug Remote Sensing bugzilla #474 [no longer available].Check results, returned by the
TIFFFdOpen()before returning and close file ifTIFFFdOpen()failed as per bug Remote Sensing bugzilla #468 [no longer available].libtiff/libtiff.def,libtiff/tif_close.c,libtiff/tiffio.h,libtiff/tif_open.c: SeparateTIFFCleanup()from theTIFFClose()in order to fix the bug Remote Sensing bugzilla #468 [no longer available].libtiff/tif_dirwrite.c: Fixed handling of writable ASCII tags that arefield_passcount=TRUEproperly. Arguably anonymous custom tags should be declared aspasscount=FALSE, but I don't want to change that without a careful review.libtiff/tif_write.c: Fixed reporting size of the buffer in case of stripped image inTIFFWriteBufferSetup(). As per bug Remote Sensing bugzilla #460 [no longer available].libtiff/tif_dir.c: Incomplete cleanup inTIFFFreeDirectory(), patch from Gerben Koopmans.libtiff/tif_dirread.c: Checkfield_passcountvalue before setting the value of undefined type, patch from Gerben Koopmans.libtiff/tiff.h,libtiff/tif_fax3.c: Fixes for AMD 64 platform as suggested by Jeremy C. Reed.libtiff/tif_win32.c: Fixed problem with_TIFFrealloc()when theNULLpointer passed. Patch supplied by Larry Grill.
Tools changes¶
tiffset: Set any libtiff supported tags. Tags can be supplied by the mnemonic name or number.
ycbcr.c: fixedmain()declaration as per: Remote Sensing bugzilla #513 [no longer available].tiffsplit: Don't forget to copy
PhotometricInterpretationtag.tiffsplit:
Fixed problem with unproperly written multibyte files. Now output files will be written using the same byte order flag as in the input image. See Remote Sensing bugzilla #574 [no longer available].
Copy
JPEGTablestag contents for JPEG compressed images. Reported by Artem Mirolubov.
tiffcp:
Close output file on normal exit.
Don't emit warnings when
Orientationtag does not present in the input image.Properly set Photometric Interpretation in case of JPEG compression of grayscale images.
Fixed problem with wrong interpretation of the
InkNamestag as per bug Remote Sensing bugzilla #466 [no longer available]. Memory leak fixed.Fixed problem with wrong
PhotometricInterpretationsetting for non-RGB images.
Contributed software changes¶
Outdated stuff removed.
Almost all programs are synchronized with the current libtiff and should compile without problems.
LZW compression kit changes¶
No changes.
