 | 
	- Display is a machine architecture
	independent image processing and display program. It can display an
	image on any workstation display running an X server. The
	image can be displayed as background image of any window. 
	
- 
	Display first determines the hardware capabilities of your
	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. 
	
  
	
		|  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 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 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
 | 
	- 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
 | 
	- Composite
	composites images to create new images. 
	
  
	
		|  Conjure
 | 
	- Conjure interprets and executes
	scripts in the Magick Scripting Language (MSL). 
	
- 
	The Magick scripting language (MSL) will primarily benefit those
	that want to accomplish custom image processing tasks but do not
	wish to program, or those that do not have access to a Perl
	interpreter or a compiler. The interpreter is called conjure and
	here is an example script: 
	
    <?xml version="1.0" encoding="UTF-8"?>
    <image size="400x400" >
      <read filename="image.gif" />
      <get width="base-width" height="base-height" />
      <resize geometry="%[dimensions]" />
      <get width="width" height="height" />
      <print output=
        "Image sized from %[base-width]x%[base-height]
         to %[width]x%[height].\n" />
      <write filename="image.png" />
    </image>
	- 
	invoked with 
	
    conjure -dimensions 400x400 incantation.msl
	- 
	All operations will closely follow the key/value pairs defined in
	PerlMagick, unless otherwise noted.
