tiffcmp

tiffcmp(1)							   User Commands							tiffcmp(1)

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 comparing data. Files are compared on a scanline-by-scanline basis after decompression. Most
       directory tags are checked, notable exceptions are GrayResponseCurve, ColorResponseCurve, and ColorMap tags. Data is not compared if any of
       the BitsPerSample, SamplesPerPixel, or ImageWidth values are not equal. By default, tiffcmp terminates if any difference is encountered.

OPTIONS

       The following options are supported:

       -l	       List each byte of image data that differs between the files.

       -t	       Ignore any differences in directory tags.

OPERANDS

       The following operands are supported:

       filex.tif       The names of the TIFF files to be compared.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWTiff			   |
       +-----------------------------+-----------------------------+
       |Interface stability	     |External			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       pal2rgb(1), tiffinfo(1), tiffcp(1), tiffmedian(1), libtiff(3)

NOTES

       Tags that are not recognized by the library are not compared. Such tags may also generate spurious diagnostics.
