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 decompres-
sion. Most directory tags are checked; notable exceptions are: GrayResponseCurve, Color-
ResponseCurve, 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.
-l List each byte of image data that differs between the files.
-t Ignore any differences in directory tags.
Tags that are not recognized by the library are not compared; they may also generate spu-
The image data of tiled files is not compared, since the TIFFReadScanline() function is
used. A error will be reported for tiled files.
The pixel and/or sample number reported in differences may be off in some exotic cases.
