ImageMagick Description
ImageMagick is an X11 package for display
and interactive manipulation of images.
To get started simply type:
display
on either an SGI or Linux workstation.
Basic documentation and links to online manual pages are below.
There is also an Adobe PDF-format manual available.
DESCRIPTION
- ImageMagick 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 at
- ftp.imagemagick.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) 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.
