FIELD_SUBFILETYPE) used to identify that tag. 625c56f5e2SFrank WarmerdamHowever, every time a new tag was added to the core, the size of the 635c56f5e2SFrank WarmerdamTIFFDirectory structure would changing, breaking any dynamically linked 645c56f5e2SFrank Warmerdamsoftware that used the private data structures.<p> 655c56f5e2SFrank Warmerdam 665c56f5e2SFrank WarmerdamAlso, any tag not recognised 675c56f5e2SFrank Warmerdamby libtiff would not be read and accessable to applications without some 685c56f5e2SFrank Warmerdamfairly complicated work on the applications part to pre-register the tags 695c56f5e2SFrank Warmerdamas exemplified by the support for "Geo"TIFF tags by libgeotiff layered on 705c56f5e2SFrank Warmerdamlibtiff. <p> 715c56f5e2SFrank Warmerdam 725c56f5e2SFrank WarmerdamAmoung other things this approach required the extension code 735c56f5e2SFrank Warmerdamto access the private libtiff structures ... which made the higher level 745c56f5e2SFrank Warmerdamnon-libtiff code be locked into a specific version of libtiff at compile time. 755c56f5e2SFrank WarmerdamThis caused no end of bug reports!<p> 765c56f5e2SFrank Warmerdam 775c56f5e2SFrank WarmerdamThe new approach is for libtiff to read all tags from TIFF files. Those that 785c56f5e2SFrank Warmerdamaren't recognised as "core tags" (those having an associated FIELD_ value, 795c56f5e2SFrank Warmerdamand place for storage in the TIFFDirectory structure) are now read into a 805c56f5e2SFrank Warmerdamdynamic list of extra tags (td_customValues in TIFFDirectory). When a new 815c56f5e2SFrank Warmerdamtag code is encountered for the first time in a given TIFF file, a new 825c56f5e2SFrank Warmerdamanonymous tag definition is created for the tag in the tag definition list. 835c56f5e2SFrank WarmerdamThe type, and some other metadata is worked out from the instance encountered. 845c56f5e2SFrank WarmerdamThese fields are known as "custom tags". <p> 855c56f5e2SFrank Warmerdam 865c56f5e2SFrank WarmerdamCustom tags can be set and fetched normally using TIFFSetField() and 875c56f5e2SFrank WarmerdamTIFFGetField(), and appear pretty much like normal tags to application code. 885c56f5e2SFrank WarmerdamHowever, they have no impact on internal libtiff processing (such as 895c56f5e2SFrank Warmerdamcompression). Some utilities, such as tiffcp will now copy these custom 905c56f5e2SFrank Warmerdamtags to the new output files. <p> 915c56f5e2SFrank Warmerdam 925c56f5e2SFrank WarmerdamAs well as the internal work with custom tags, new C API entry points 935c56f5e2SFrank Warmerdamwere added so that extension libraries, such as libgeotiff, could 945c56f5e2SFrank Warmerdamdefine new tags more easily without accessing internal data structures. 955c56f5e2SFrank WarmerdamBecause tag handling of extension tags is done via the "custom fields" 965c56f5e2SFrank Warmerdammechanism as well, the definition provided externally mostly serves to provide 975c56f5e2SFrank Warmerdama meaningful name for the tag. 985c56f5e2SFrank Warmerdam 995c56f5e2SFrank WarmerdamThe addition of "custom tags" and the altered approach to extending libtiff 1005c56f5e2SFrank Warmerdamwith externally defined tags is the primary reason for the shift to the 1015c56f5e2SFrank Warmerdam3.6.x version number from 3.5.x.<p> 1025c56f5e2SFrank Warmerdam 1035c56f5e2SFrank Warmerdam<P><HR WIDTH=65% ALIGN=left> 1045c56f5e2SFrank Warmerdam<!---------------------------------------------------------------------------> 1055c56f5e2SFrank Warmerdam 1065c56f5e2SFrank Warmerdam<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> 1075c56f5e2SFrank Warmerdam 1085c56f5e2SFrank Warmerdam<UL> 1095c7b0ab0SAndrey Kiselev<li> configure, config.site: Fix for large files (>2GiB) support.

Apparently the problem was incorporated since 2745c56f5e2SFrank Warmerdam3.5.5, presumably during the OJPEG/JPEG work recently. 2755c56f5e2SFrank Warmerdam 2765c56f5e2SFrank Warmerdam<li> libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1 2775c56f5e2SFrank Warmerdam(defined in tiffconf.h - 1 by default) then the RGBA interface 2785c56f5e2SFrank Warmerdamwill assume that a fourth extra sample is ASSOCALPHA if the 2795c56f5e2SFrank WarmerdamEXTRASAMPLE value isn't set for it. This changes the behaviour of 2805c56f5e2SFrank Warmerdamthe library, but makes it work better with RGBA files produced by 2815c56f5e2SFrank Warmerdamlots of applications that don't mark the alpha values properly. 2825c56f5e2SFrank WarmerdamAs per bugs 93 and 65. 2835c56f5e2SFrank Warmerdam 2845c56f5e2SFrank Warmerdam<li> libtiff/tif_jpeg.c: allow jpeg data stream sampling values to 2855c56f5e2SFrank Warmerdamoverride those from tiff directory.
