This software distribution comes with a small collection of programs
for converting non-TIFF format images to TIFF and for manipulating
and interogating the contents of TIFF images.
Several of these tools are useful in their own right.
Many of them however are more intended to serve as programming
examples for using the TIFF library.
||Display information about one or more TIFF files.
||Display the verbatim contents of the TIFF directory in a
file (it's very useful for debugging bogus files that you may get from
someone that claims they support TIFF)
||Copy, concatenate, and convert TIFF images (e.g.
switching from Compression=5 to Compression=1)
||Convert TIFF images to PostScript
||Compare the contents of two TIFF files (it does
not check all the directory information, but does check all the data)
||A simple program to convert a color image to grayscale
||A quick hack that converts Sun rasterfile format images to
TIFF -- it's less than complete
||Convert an RGB, grayscale, or bilevel TIFF image to a
YCbCr TIFF image; it's mainly provided for testing
||A quick hack that converts GIF 87a format images to TIFF
||A quick hack that converts PPM format images to TIFF
||Convert raw Group 3 or Group 4 facsimile data to TIFF
||Convert a Palette-style image to a full color RGB image by
applying the colormap
||Dither a b&w image into a bilevel image (suitable for
use in creating fax files)
||Create one or more single-image files from a (possibly)
||Convert a Group 3- or Group 4- compressed TIFF to PostScript
that is significantly more compressed than is generated by tiff2ps
(unless tiff2ps writes PS Level II)
||Copy a bilevel TIFF to one that includes 8-bit greyscale
"thumbnail images" for each page; it is provided as an example of
how one might use the SubIFD tag
(and the library support for it)
||A version of Paul Heckbert's median cut program
that reads an RGB TIFF image, and creates a TIFF palette file as a
result; it's useful for converting full-color RGB images to 8-bit
color for your friends that have cheapo 8-bit framebuffers.
||A program to convert SGI image files to TIFF. This
program is only useful on SGI machines as it uses -limage.
