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.<p> - -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. <p> - -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!<p> - -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". <p> - -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. <p> - -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.<p> - -<P><HR WIDTH=65% ALIGN=left> -<!---------------------------------------------------------------------------> - -<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> - -<UL> -<li> configure, config.site: Fix for large files (>2GiB) support.

See bug 119. - -<li> tif_dirread.c: avoid div-by-zero if rowbytes is zero in chop func as -per bug 111. - -<li> 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.

Apparently the problem was incorporated since -3.5.5, presumably during the OJPEG/JPEG work recently. - -<li> 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. - -<li> libtiff/tif_jpeg.c: allow jpeg data stream sampling values to -override those from tiff directory.
