JPEG2000 support?

[MarcG2]

Is there a way I can embed jpeg2000 images into a pdf without converting them?
I'm looking for better compression than what JPEG offers. And it seems JPEG2000 is my only choice since pdfs are very limited in what formats they support. Any advice would be appreciated.

Support for the JPXDecode filter and the JPEG 2000 file formats was not yet added to PDFsharp. This enhancement has low priority for us at the moment as JPEG 2000 is not widely used.

Since PDFsharp is open source, you (or someone else) can add JPXDecode and JPEG 2000 similar to the current implementation of the DCTDecode filter and the JFIF file format.
