ImageMagick(1)ImageMagick(1)NAMEImageMagick - ImageMagick is an X11 package for display
and interactive manipulation of images.
DESCRIPTION
ImageMagick, version 5.3.9, is a robust collection of
tools and libraries to read, write, and manipulate an
image in any of the more popular image formats including
GIF, JPEG, PNG, PDF, and Photo CD. With ImageMagick you
can create GIFs dynamically making it suitable for Web
applications. You can also resize, rotate, sharpen, color
reduce, or add special effects to an image and save your
completed work in the same or differing image format.
Although the software is copyrighted, it is available for
free and can be redistributed without fee. ImageMagick is
available via anonymous FTP as
ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick-5.3.9.tar.gz.
display
Display is a machine architecture independent image
and display program. It can display an image on
any workstation display running an X server.
Display can read and write many of the more popular
image formats (e.g. JPEG, TIFF, PNM, Photo CD,
etc.). You can perform these functions on the
image:
o load an image from a file
o display the next image
o display the former image
o display a sequence of images as a slide show
o write the image to a file
o print the image to a Postscript printer
o delete the image file
o create a Visual Image Directory
o select the image to display by its thumbnail rather than name
o undo last image transformation
o copy a region of the image
o paste a region to the image
o restore the image to its original size
o refresh the image
o half the image size
o double the image size
o resize the image
o crop the image
o cut the image
o flop image in the horizontal direction
o flip image in the vertical direction
o rotate the image 90 degrees clockwise
o rotate the image 90 degrees counter-clockwise
o rotate the image
o shear the image
o trim the image edges

o discard all images and exit program
o change the level of magnification
o display images specified by a World Wide Web (WWW) uniform resource locator (URL)
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 the
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.

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.
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 its magic number. To specify a particular image
format, precede the filename with an image format
name and a colon (i.e. ps:image) or specify the
image type as the filename suffix (i.e. image.ps).
Specify file as - for standard input or output. If
file has the extension .Z, the file is decoded with
uncompress.
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.
identify
describes the format and characteristics of one or
more image files. It will also report if an image
is incomplete or corrupt. The information
displayed includes the scene number, the file name,
the width and height of the image, whether the
image is colormapped or not, the number of colors
in the image, the number of bytes in the image, the
format of the image (JPEG, PNM, etc.), and finally

the number of seconds it took to read and process
the image.
composite
Combine composites images to create new images.
