> Hello.. looking for a patch (I understand) for tiffcp 3.8.2 to invert > min-is-white to min-is-black. Is this available Two possibilities come to mind depending upon your needs. If all you want is to correct an improperly set tag, why not use tiffset. If you need to rewrite the data to pacify lame TIFF readers, use tiffcrop with the -I flag. The support is limited to grayscale and bilevel images and it does not take into account any tags that might imply other than linear scaling of pixel values, eg 0 becomes 255 and 255 becomes 0 for 8 bit grayscale.
