im_Type2char(3) converts a Type code (such as MULTIBAND, see <vips/vips.h>) to a string. im_BandFmt2char(3) , im_Coding2char(3) and im_Compression2char(3) are similar. All return "<unknown Type>" if the value passed is outside the expected range.
im_char2Type(3) converts the other way, returning a small integer for success, and -1 for failure. Again, im_char2BandFmt(3) , im_char2Coding(3) and im_char2Compression are similar.
