The options are different for 4/8/24 bpp. The values correspond to the positions of the respective compression types in the drop-down list. This will have to make do until someone does a vast re-write of the TIFF export options code! Note that LZW_TIFF and HUFFMAN_TIFF are at the same position: this is because they don't actually appear at the same time. For 1bpp, the options are { uncompressed, huffman, g3 ... } For 8ppp, the options are { uncompressed, lzw } define UNCOMPRESSED_TIFF 0 define LZW_TIFF 1 define HUFFMAN_TIFF 1 define G3FAX_TIFF 2 define G4FAX_TIFF 3 define PACKBITS_TIFF 4 define TWODENCODING_TIFF 5 BODGE: We get some bad pixel cropping on some images if we use doubles.
