TIFFDUMP

tiffdump − print verbatim information about TIFF files

tiffdump [ options ] name ...

tiffdump displays directory information from files created according to the Tag Image File Format, Revision 6.0. The header of each TIFF file (magic number, version, and first directory offset) is displayed, followed by the tag contents of each directory in the file. For each tag, the name, data type, count, and value(s) is displayed. When the symbolic name for a tag or data type is known, the symbolic name is displayed followed by it’s numeric (decimal) value. Tag values are displayed enclosed in ‘‘<>’’ characters immediately preceded by the value of the count field. For example, an ImageWidth tag might be displayed as ‘‘ImageWidth (256) SHORT (3) 1<800>’’.

tiffdump is particularly useful for investigating the contents of TIFF files that libtiff does not understand.
