TIFF and LibTiff Mail List Archive

2004.09.10 05:19 "[Tiff] tiffconf.h defunct?", by Bob Friesenhahn

Past versions libtiff have included a tiffconf.h header which provides oodles of _SUPPORT defines so that client applications can see what features are provided in the library. For example, if CCITT_SUPPORT is defined, then CCIT FAX compressionis supported. I discovered that this was missing in the CVS/alpha version when I noticed that features of GM's TIFF support were silently missing.

While these defines were also used to configure the library, portable applications also use them to decide how to best use the library.

If an equivalent set of _SUPPORT defines is not provided by the configure-based build environment, many significant applications will silently break.
