Custom Tag Support

+ +The approach to extending libtiff with custom tags has changed radically. +Previously, all internally supported TIFF tags had a place in the +private TIFFDirectory structure within libtiff to hold the values (if read), +and a "field number" (ie. FIELD_SUBFILETYPE) used to identify that tag. +However, every time a new tag was added to the core, the size of the +TIFFDirectory structure would changing, breaking any dynamically linked +software that used the private data structures.

+ +Also, any tag not recognised +by libtiff would not be read and accessable to applications without some +fairly complicated work on the applications part to pre-register the tags +as exemplified by the support for "Geo"TIFF tags by libgeotiff layered on +libtiff.

+ +Amoung other things this approach required the extension code +to access the private libtiff structures ... which made the higher level +non-libtiff code be locked into a specific version of libtiff at compile time. +This caused no end of bug reports!

+ +The new approach is for libtiff to read all tags from TIFF files. Those that +aren't recognised as "core tags" (those having an associated FIELD_ value, +and place for storage in the TIFFDirectory structure) are now read into a +dynamic list of extra tags (td_customValues in TIFFDirectory). When a new +tag code is encountered for the first time in a given TIFF file, a new +anonymous tag definition is created for the tag in the tag definition list. +The type, and some other metadata is worked out from the instance encountered. +These fields are known as "custom tags".

+ +Custom tags can be set and fetched normally using TIFFSetField() and +TIFFGetField(), and appear pretty much like normal tags to application code. +However, they have no impact on internal libtiff processing (such as +compression). Some utilities, such as tiffcp will now copy these custom +tags to the new output files.

+ +As well as the internal work with custom tags, new C API entry points +were added so that extension libraries, such as libgeotiff, could +define new tags more easily without accessing internal data structures. +Because tag handling of extension tags is done via the "custom fields" +mechanism as well, the definition provided externally mostly serves to provide +a meaningful name for the tag. + +The addition of "custom tags" and the altered approach to extending libtiff +with externally defined tags is the primary reason for the shift to the +3.6.x version number from 3.5.x.

+ +

+ + +CHANGES IN THE SOFTWARE CONFIGURATION: + +

configure, config.site: Fix for large files (>2GiB) support. New +option in the config.site: LARGEFILE="yes". Should be enougth for the large +files I/O. + +

+ +

+ + + +CHANGES IN LIBTIFF: + +

libtiff/tif_getimage.c: New function TIFFReadRGBAImageOriented() +implemented to retrieve raster array with user-specified origin position. + +
libtiff/tif_fax3.c: Fix wrong line numbering. + +
libtiff/tif_dirread.c: Check field counter against number of fields. + +
Store a list of opened IFD to prevent directory looping. + +
libtiff/tif_jpeg.c: modified segment_height calculation to always +be a full height tile for tiled images. Also changed error to just +be a warning. + +
libtiff/tif_lzw.c: fixed so that decoder state isn't allocated till +LZWSetupDecode(). Needed to read LZW files in "r+" mode. + +
libtiff/tif_dir.c: fixed up the tif_postdecode settings responsible +for byte swapping complex image data. + +
libtiff/tif_open.c: Removed error if opening a compressed file +in update mode bug (198). + +
libtiff/tif_write.c: TIFFWriteCheck() now fails if the image is +a pre-existing compressed image. That is, image writing to pre-existing +compressed images is not allowed. + +
html/man/*.html: Web pages regenerated from man pages. + +
libtiff/tif_jpeg.c: Hack to ensure that "boolean" is defined properly +on Windows so as to avoid the structure size mismatch error from libjpeg +(bug 188). + +
libtiff/tiff.h: #ifdef USING_VISUALAGE around previous Visual Age +AIX porting hack as it screwed up gcc. (bug 39) + +
libtiff/tiff.h: added COMPRESSION_JP2000 (34712) for LEAD tools +custom compression. + +
libtiff/tif_dirread.c: Another fix for the fetching SBYTE arrays +by the TIFFFetchByteArray() function. (bug 52) + +
libtiff/tif_dirread.c: Expand v[2] to v[4] in TIFFFetchShortPair() +as per bug 196. + +
libtiff/tif_lzw.c: Additional consistency checking added in +LZWDecode() and LZWDecodeCompat() fixing bugs 190 and 100. + +
libtiff/tif_lzw.c: Added check for valid code lengths in LZWDecode() +and LZWDecodeCompat(). Fixes bug 115. + +
tif_getimage.c: Ensure that TIFFRGBAImageBegin() returns the +return code from the underlying pick function as per bug 177. + +
libtiff/{tif_jpeg.c,tif_strip.c,tif_print.c}: Hacked tif_jpeg.c to +fetch TIFFTAG_YCBCRSUBSAMPLING from the jpeg data stream if it isn't +present in the tiff tags as per bug 168. + +
libtiff/tif_jpeg.c: Fixed problem with setting of nrows in +JPEGDecode() as per bug 129. + +
libtiff/tif_read.c, libtiff/tif_write.c: TIFFReadScanline() and +TIFFWriteScanline() now set tif_row explicitly in case the codec has +fooled with the value as per bug 129. + +
libtiff/tif_ojpeg.c: Major upgrade from Scott. Details in bug 156. + +
libtiff/tif_open.c: Pointers to custom procedures +in TIFFClientOpen() are checked to be not NULL-pointers. + +
libtiff/tif_lzw.c: Assertions in LZWDecode and LZWDecodeCompat +replaced by warnings. Now libtiff should read corrupted LZW-compressed +files by skipping bad strips as per bug 100. + +
libtiff/: tif_dirwrite.c, tif_write.c, tiffio.h: +TIFFCheckpointDirectory() +routine added as per bug 124. The +TIFFWriteDirectory +man page discusses this new function as well as the related +TIFFRewriteDirectory(). + +
libtiff/: tif_codec.c, tif_compress.c, tiffiop.h, tif_getimage.c: +Introduced +additional members tif->tif_decodestatus and tif->tif_encodestatus +for correct handling of unconfigured codecs (we should not try to read +data or to define data size without correct codecs). See bug 119. + +
tif_dirread.c: avoid div-by-zero if rowbytes is zero in chop func as +per bug 111. + +
libtiff/: tiff.h, tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c, +tif_dirwrite.c: Dwight Kelly added get/put code for new tag XMLPACKET as +defined in Adobe XMP Technote. Added missing INKSET tag value from TIFF 6.0 +spec INKSET_MULTIINK (=2). Added missing tags from Adobe TIFF technotes: +CLIPPATH, XCLIPPATHUNITS, YCLIPPATHUNITS, OPIIMAGEID, OPIPROXY and +INDEXED. Added PHOTOMETRIC tag value from TIFF technote 4 ICCLAB (=9). + +
libtiff/tif_getimage.c: Additional check for supported codecs added in +TIFFRGBAImageOK, TIFFReadRGBAImage, TIFFReadRGBAStrip and TIFFReadRGBATile now +use TIFFRGBAImageOK before reading a per bug 110. + +
libtiff/: tif_dir.c, tif_dir.h, tif_dirinfo.c, tif_dirread.c, +tif_dirwrite.c: Added routine +TIFFDataWidth for determining +TIFFDataType sizes instead of working with tiffDataWidth array +directly as per bug 109. + +
libtiff/: tif_dirinfo.c, tif_dirwrite.c: Added possibility to +read broken TIFFs with LONG type used for TIFFTAG_COMPRESSION, +TIFFTAG_BITSPERSAMPLE, TIFFTAG_PHOTOMETRIC as per bug 99. + +
libtiff/{tiff.h,tif_fax3.c}: Add support for __arch64__ as per bug 94. + +
libtiff/tif_read.c: Fixed TIFFReadEncodedStrip() to fail if the +decodestrip function returns anything not greater than zero as per bug 97. + +
libtiff/tif_jpeg.c: fixed computation of segment_width for +tiles files to avoid error about it not matching the +cinfo.d.image_width values ("JPEGPreDecode: Improper JPEG strip/tile +size.") for ITIFF files. Apparently the problem was incorporated since +3.5.5, presumably during the OJPEG/JPEG work recently. + +
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 +the library, but makes it work better with RGBA files produced by +lots of applications that don't mark the alpha values properly. +As per bugs 93 and 65. + +
libtiff/tif_jpeg.c: allow jpeg data stream sampling values to +override those from tiff directory. This makes this work with +ImageGear generated files. + +

+ +
