ImageMagick is a collection of X11 image processing and display utilities. It
is available on export.lcs.mit.edu as contrib/ImageMagick.tar.Z.

Display
Display is a machine architecture independent image
processing and display program. It can display an image on
any workstation display running an X server. Display first
determines the hardware capabilities of the workstation. If
the number of unique colors in the image is less than or
equal to the number the workstation can support, the image
is displayed in an X window. Otherwise the number of colors
in the image is first reduced to match the color resolution
of the workstation before it is displayed.
This means that a continuous-tone 24 bits/pixel image can
display on a 8 bit pseudo-color device or monochrome device.
In most instances the reduced color image closely resembles
the original. Alternatively, a monochrome or pseudo-color
image can display on a continuous-tone 24 bits/pixels
device.
Import
Import reads an image from any visible window on an X server
and outputs it as an image file. You can capture a single
window, the entire screen, or any rectangular portion of the
screen. You can use display (see display(1)) utility for
redisplay, printing, editing, formatting, archiving, image
processing, etc. of the captured image.
The target window can be specified by id, name, or may be
selected by clicking the mouse in the desired window. If
you press a button and then drag, a rectangle will form
which expands and contracts as the mouse moves. To save the
portion of the screen defined by the rectangle, just
release the button. The keyboard bell is rung once at the
beginning of the screen capture and twice when it completes.
XtoPS
XtoPS reads an image from any visible window on an X server
and outputs it as Encapsulated Postscript. You can capture
a single window, the entire screen, or any rectangular
portion of the screen. You can view the captured screen
with any Postscript compatible viewer or printer. The
Postscript is displayed in color on viewers or printers that
support color, otherwise it is displayed as grayscale.
The target window can be specified by id, name, or may be
selected by clicking the mouse in the desired window. If
you press a button and then drag, a rectangle will form
which expands and contracts as the mouse moves. To save the
portion of the screen defined by the rectangle, just release
the button. The keyboard bell is rung once at the beginning
of the screen capture and twice it completes.
Animate
Animate displays a sequence of images on any workstation
display running an X server. Animate first determines the
hardware capabilities of the workstation. If the number of
unique colors in an image is less than or equal to the
number the workstation can support, the image is displayed
in an X window. Otherwise the number of colors in the image
is first reduced to match the color resolution of the
workstation before it is displayed.
This means that a continuous-tone 24 bits/pixel image can
display on a 8 bit pseudo-color device or monochrome device.
In most instances the reduced color image closely resembles
the original. Alternatively, a monochrome or pseudo-color
image sequence can display on a continuous-tone 24
bits/pixels device.
Montage
Montage creates a composite image by combining several
separate images. The images are tiled on the composite
image with the name of the image optionally appearing just
below the individual tile.
Mogrify
Mogrify transforms an image or a sequence of images. These
transforms include image scaling, image rotation, color
reduction, and others. The transmogrified image overwrites
the original image.
Convert
Convert converts an input file using one image format to an
output file with a differing image format. By default, the
image format is determined by it's magic number. To specify
a particular image format, precede the filename with an
image format name and a colon (i.e. mtv:image) or specify
the image type as the filename suffix (i.e. image.mtv).
Specify file as - for standard input or output. If file has
the extension .Z, the file is decoded with uncompress.
Convert recognizes the following image formats:
Tag Description

XTP
Xtp is a utility for retrieving, listing, or printing files
from a remote network site, or sending files to a remote
network site. Xtp performs most of the same functions as
the ftp program, but does not require any interactive
commands. You simply specify the file transfer task on the
command line and xtp performs the task automatically.
