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.
