tiffcmp - compare two TIFF files


tiffcmp [ options ] file1.tif file2.tif


Tiffcmp compares the tags and data in two files created according to the Tagged Image File Format, Revision 6.0. The schemes used for compressing data in each file are immaterial when data are compared-data are compared on a scanline-by-scanline basis after decompression. Most directory tags are checked; notable exceptions are: GrayResponseCurve, ColorResponseCurve, and ColorMap tags. Data will not be compared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal. By default, tiffcmp will terminate if it encounters any difference.


List each byte of image data that differs between the files.
Ignore any differences in directory tags.


Tags that are not recognized by the library are not compared; they may also generate spurious diagnostics.
