NAME
tiffcmp - compare two TIFF files
SYNOPSIS
tiffcmp [ options ] file1.tif file2.tif
DESCRIPTION
Tiffcmp compares the tags and data in two files created according to
the Tagged Image File Format, Revision 6.0. The schemes used for com-
pressing 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 differ-
ence.
OPTIONS
-l List each byte of image data that differs between the files.
-z number
List specified number of image data bytes that differs between
the files.
-t Ignore any differences in directory tags.
BUGS
Tags that are not recognized by the library are not compared; they may
also generate spurious diagnostics.
The image data of tiled files is not compared, since the TIFFReadScan-
line() function is used. An error will be reported for tiled files.
The pixel and/or sample number reported in differences may be off in
some exotic cases.
