Hi
At the moment Imaging does not support saving to JPEG, and can only
write TIFF in black and white, and RGB (see photometricInterpretation
in the writeImage() method in
org/apache/commons/imaging/formats/tiff/write/TiffImageWriterBase.java).
I don't think a patch for CMYK would be hard to write though.
Regards
Damjan
