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 imma-
terial when data are compared-data are compared on a
scanline-by-scanline basis after decompression. Most direc-
tory tags are checked; notable exceptions are: GrayRespon-
seCurve, ColorResponseCurve, and ColorMap tags. Data will
not be compared if any of the BitsPerSample, SamplesPer-
Pixel, 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
-t Ignore any differences in directory tags.
Tags that are not recognized by the library are not com-
pared; they may also generate spurious diagnostics.
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.
