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 com- pared if any of the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal. By default, tiffcmp will terminate if it encoun- ters any difference. OPTIONS
-l List each byte of image data 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. A error will be reported for tiled files. The pixel and/or sample number reported in differences may be off in some exotic cases. SEE ALSO
