GraphicsMagick is doing something a bit odd though since it uses
(void) TIFFSetField(tiff,TIFFTAG_JPEGCOLORMODE,JPEGCOLORMODE_RGB);
The only other choice appears to be JPEGCOLORMODE_RAW. Maybe JPEGCOLORMODE_RAW should be used for CMYK?
I tried passing JPEGCOLORMODE_RAW and it made no difference. Libtiff still added a subsampling tag.
Bob,
there is a known problem with the raw JPEG interface in tif_jpeg.c. I t should be fixed at some point in the future...
