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
TIFFReadScanline() 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.
