I am working on package with extra content for Vampyre Imaging Library. That means additional image file formats, new extensions, demos, and other stuff.
File formats in extras will also include JPEG2000. Reason why it won't be in the core library is this: there is no native Pascal library for loading/saving JPEG2000 images (at least I haven't found one) so Imaging will link to C library compiled to object files (OpenJPEG most probably). Therefore it won't work on all platforms supported by Imaging (and thus cannot be included in core library).
There is also PCX loader, there will be PNM (for PBM, PGM, PPM, and PAM) loader/saver, and maybe even GIF support (if there will be enough time to implement it). I have converted my old Daggerfall image/texture loaders to Imaging too and added Redguard and BattleSpire support.
First version of extras package will be released around the end of 2006. New Imaging release will be made too because stuff in extras depends on some changes made in core library since 0.20 release. Current working version of Imaging and extras package is in project's SubVersion repository.
