Hi,

     I am working on an application which compresses the Video memory buffer using JPEG's ijl20 library. It works perfectly fine with the 24-bit buffer generated by my Display driver. To meet a new requirement, I am creating a 16-bit display driver. But, JPEG compression fails during ijlWrite throwing error either of type IJL_UNSUPPORTED_SUBSAMPLING or IJL_INVALID_JPEG_PROPERTIES. I happened to see at various places on the net that old JPEG doesn't support 16-bit channel whereas the new IPP JPEG 2000 codec does support it. I would be really grateful if u clarify this doubt of mine that whether ijl20 has support for 16 bit channel or not.

Regards,

Bhavani Madiraju
