I'm interested about JPEG 2000 in TIFF.

Is an integration of this compression as a new codec in libtiff is planned? At the matter of fact it's only the writting of an interface file tif_jp2.c file as the tif_jpeg.c file for standard jpeg...

Thanks in advance for all informations about JPEG 2000 in TIFF,

I have been thinking about the idea of embedding jpc (jpeg 2000 code streams) as TIFF tiles or strips. The idea would be that each chunk of strip or tile data would be a free standing JPEG 2000 data stream in "jpc" format. That is they would not have the extra .jp2 wrapper info but there would still potentially be a fair amount of information duplication between the jpc streams.

Various libraries, such as JasPer, should be able to provide the JPEG2000 jpc read/write support.

If we take this approach we would need to assign a new compression code, and implement a tif_jpc_jasper.c or something like that.

Note that this would be a proprietary compression, otherwise you need to ask Adobe for a new compression code.
