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 ftp://ftp.wizards.dupont.com/pub/ImageMag-
ick/ImageMagick-4.0.5.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. Dis-
play 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) 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 con-
tracts 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 work-
station 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 work-
station 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 resolu-
tion 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. Alter-
natively, 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 sev-
eral separate images. The images are tiled on the
composite image with the name of the image option-
ally appearing just below the individual tile.
convert
Convert converts an input file using one image for-
mat to an output file with a differing image for-
mat. 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 dis-
played 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.
xtp Xtp is a utility for retrieving, listing, or print-
ing 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.
