- When your sys manager comes back, assuming she is installing CDA
- library v2.0, you will find that GIF is also a supported type.
-
- The main strength of the CDA library is in text and compound document
- conversions rather than image format conversions (IMHO) stuff like
- wordperfect -> ODA, SGML -> Microsoft word, that sort of thing.

-
- I thought TIFF readers were supposed to skip tags they didn't understand.
-
- By the way does tifflib support TIFF 6.0 yet?
