NAME
ImageMagick - ImageMagick is an X11 package for display
and interactive manipulation of images.
DESCRIPTION
ImageMagick is an X11 package for display and interactive
manipulation of images. The package includes tools for
image conversion, annotation, compositing, animation, and
creating montages. ImageMagick can read and write many of
the more popular image formats (e.g. JPEG, TIFF, PNM, XPM,
Photo CD, etc.). ImageMagick is available via anonymous
FTP as
contrib/applications/ImageMagick/ImageMagick-3.6.3.tar.gz
on ftp.x.org.
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 invert the colors of the image
o vary the color brightness
o vary the color saturation

o vary the image hue
o gamma correct the image
o sharpen the image contrast
o dull the image contrast
o perform histogram equalization on the image
o perform histogram normalization on the image
o negate the image colors
o toggle the colormap type: : Shared or Private
o reduce the speckles within an image
o eliminate peak noise from an image
o detect edges within the image
o emboss an image
o oil paint an image
o convert the image to grayscale
o set the maximum number of unique colors in the image
o segment the image by color
o apply image processing techniques to a region of
interest
o annotate the image with text
o draw on the image
o edit an image pixel color
o edit the image matte information
o composite an image with another
o add a border to the image
o surround image with an ornamental border
o add an image comment
o display image centered on a backdrop
o display image to background of a window
o display information about the image
o display information about this program
o discard all images and exit program
o change the level of magnification
o display images specified by a World Wide Web (WWW)

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 it's 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.

combine
Combine combines images to create new images.
segment
Segment segments an image by analyzing the histograms
of the color components and identifying units that
are homogeneous with the fuzzy c-means technique.
The scale-space filter analyzes the histograms of the
three color components of the image and identifies a
set of classes. The extents of each class is used to
coarsely segment the image with thresholding. The
color associated with each class is determined by the
mean color of all pixels within the extents of a
particular class. Finally, any unclassified pixels
are assigned to the closest class with the fuzzy c-
means technique.
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.
