This document describes the changes made to the software between the previous and current versions (see above). If you don't find something listed here, then it was not done in this timeframe, or it was not considered important enough to be mentioned. The following information is located here:
Major changes¶
Replace runtime endianness check with the compile time one.
Added support for the new predictor type (floating point predictor), defined at the TIFF Technical Note 3.
Added Support for custom tags, passed by value.
Added support for all DNG tags.
Software configuration changes¶
Do not use empty
-Roption when linking with--enable-rpath.Added workaround for OpenBSD/MirOS soname problem as per bug Remote Sensing bugzilla #838 [no longer available]
Fixed parallel compilation of the libtiff and libtiffxx libraries as per bug Remote Sensing bugzilla #826 [no longer available]
configure.ac,libtiff/Makefile.am: Use libtool machinery to passrpathoption.make.opt: Build with Win32 CRT library by default.
Library changes¶
tiffiop.h,tif_open.c: Added open option "h" to avoid reading the first IFD when needed. As per bug Remote Sensing bugzilla #875 [no longer available]tiff.h: Use correct int size on Sparc 64bit/Sun compiler platform. As per bug Remote Sensing bugzilla #855 [no longer available]tif_dirinfo.c: Added support forClipPath,XClipPathUnitsandYClipPathUnitstags.tif_dirinfo.c,tif_dir.h,tif_dir.c,tif_print.c: MakeDocumentName,Artist,HostComputer,ImageDescription,Make,Model,Copyright,DateTime,PageName,TextureFormat,TextureWrapModesandTargetPrintertags custom.tif_jpeg.c: Cleanup the codec state depending onTIFF_CODERSETUPflag (to fix memory leaks).tif_dirwrite.c: Usetdir_countwhen callingTIFFCvtNativeToIEEEDouble()in theTIFFWriteDoubleArray()function as per bug Remote Sensing bugzilla #845 [no longer available]tif_dirinfo.c,tif_print.c:TIFFFetchByteArray()returnsuint16array when fetching theBYTEandSBYTEfields, so we should consider result as pointer touint16array and not as array of char. As per bug Remote Sensing bugzilla #831 [no longer available]tif_dir.c: More efficient custom tags retrieval as per bug Remote Sensing bugzilla #830 [no longer available]tif_win32.c: UseFILE_SHARE_READ | FILE_SHARE_WRITEshare mode inCreateFile()call as per bug Remote Sensing bugzilla #829 [no longer available]tif_jpeg.c: Substantial fix for addtiffo problems with JPEG encoded TIFF files. Pre-allocate lots of space for jpegtables in directory.tif_dirread.c: Changed the code that computesstripbytecount[0]if it appears bogus to ignore ifstripoffset[0]is zero. This is a common case with GDAL indicating a "null" tile/strip.tif_jpeg.c: addedLIB_JPEG_MK1support inJPEGDecodeRaw().tif_dirread.c: Ensure that broken files with too many values inTIFFFetchPerSampleShorts(),TIFFFetchPerSampleLongs()andTIFFFetchPerSampleAnys()work ok instead of crashing. Remote Sensing bugzilla #843 [no longer available]tif_predict.h,tif_predict.c: Added ability to decode and encode floating point predictor, as per TIFF Technical Note 3. See http://chriscox.org/TIFF_TN3_Draft2.pdf for details.tiffio.h,tiffiop.h,tif_dir.c,tif_read.c,tif_swab.c: Added_TIFFSwab24BitData()andTIFFSwabArrayOfLong()functions used to swap 24-bit floating point values.tiff.h: Added predictor constants.tiffiop.h,tif_dir.c: Useuint32type for appropriate values in_TIFFVSetField()function. Inspired by the bug Remote Sensing bugzilla #816 [no longer available]tif_open.c: Do not read header in case the output file should be truncated (Ron).tif_dirinfo.c,tif_config.h.vc: Uselfind()instead ofbsearch()in_TIFFFindFieldInfoByName()function (Ron).tif_dir.c,tif_print.c: Properly handle all data types in custom tags.dirinfo.c: Added DNG tags.tiff.h: Added missed DNG tag (LensInfo); added DNG 1.1.0.0 tags.tif_dir.c,tif_print.c: Added Support for custom tags, passed by value.tiff.h,tif_dirinfo.c,tiffiop.h: Added EXIF related tags.
Tools changes¶
tiff2pdf.c: Print two characters per loop in thet2p_write_pdf_trailer(). As per bug Remote Sensing bugzilla #594 [no longer available]tiffgt.c: Use MacOS X OpenGL framework when appropriate. As per bug Remote Sensing bugzilla #844 [no longer available]ppm2tiff.c: Fixed format string when read PPM file header with thefscanf()function. As per bug Remote Sensing bugzilla #861 [no longer available]tiffsplit.c: Check forJPEGTablestag presence before copying.tiff2pdfr.c: Calculate the tile width properly; added new option "-b" to use interpolation in output PDF files (Bruno Ledoux).tiffdither.c: Copy the PhotometricInterpretation tag from the input file.tif2pdf.c: Fixed problem with alpha channel handling as per bug Remote Sensing bugzilla #794 [no longer available].
Contributed software changes¶
addtiffo/tif_overview.c,addtiffo/tif_ovrcache.c,addtiffo/tif_ovrcache.h: Make overviews working for contiguous images.
