Image Processing
Image processing is a vague term. At the very least, it ought to mean
things like adjusting color maps, contrast, edge definition and so on.
At any rate, here are some programs which do these things.
- ImageMagick -- ImageMagick is actually a
collection of programs, described in a
man page.
However, the best way to access the image processing tools is to call
an image up with
display, and click on the image to get a
menu of options.
- xv --
xv is the standard X viewer,
but it also has a menu of image processing options. In particular,
its Color Map Editor displays the palette of an image, so you can find
the index of a particular color in the image. This is useful, for
example, in turning some part of an image transparent for display on a
web page. More details are available through its
man page.
- imgworks -- ImageWorks is an SGI program. Though it
functions much the same as other packages, it has the advantage of
excellent online
documentation via the SGI InSight
system. It is not available on every machine. Try abel.
- Adobe Photoshop -- At the very high end of
graphic arts image processing, Photoshop will do everything you can
think of, and a lot of other stuff you can't. You can compose images
as well as alter them, and naturally, it works well with Adobe
Illustrator. It only runs on one Macintosh, so ask about it if you
need it.
There are many, many more utility programs for image processing.
Consult the image utilities page.
