- ImageMagick 3.0
-
- Version 3.0 of ImageMagick is now available. ImageMagick is an X11
- package for display and interactive manipulation of images. The
- package includes tools for image conversion, editing, annotation,
- compositing, animation, and creating montages. ImageMagick can read
- and write many of the more popular image formats (e.g. JPEG, TIFF, PNM,
- etc.). ImageMagick is available via anonymous FTP on ftp.x.org as
- contrib/ImageMagick-3.0.tar.gz. A brief description of each
- of the programs in ImageMagick follows.
-
-
- Display
-
- Display is a machine architecture independent image
- processing and display program. It can display an image on
- any workstation display running an X server. Display first
- determines the hardware capabilities of the workstation. If
- the number of unique colors in the 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 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 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.
-
-
- 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.
-
-
- 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.
-
- Convert recognizes the following image formats:
-

-
-
- 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.
