I finally released first version of JPEG 2000 for Pascal library. It’s based on translated header and precompiled OpenJpeg library that was part of Imaging for a long time – now released separately.

There’s header translation working with both Delphi and FPC and original C library precompiled to object files (Delphi) and static libraries (FPC for Win32, Linux x86/x64, and Mac OS X).

I’ve written simple TBitmap descendant that loads and saves JPEG 2000 images. It’s only for Delphi now – can’t do LCL version with just few IFDEFS, there are lot more changes between VCL and LCL TBitmaps. I plan to write separate LCL version for one of upcoming releases (using TFPCustomImageWriter and TFPCustomImageReader classes).

You can get JPEG 2000 for Pascal library at it’s project page.
