G ImageMagick ' TM, 7 version 3.7.7, is a package for display and interactive M manipulation of images for the X Window System. It is written in C and M interfaces to the X library, and therefore does not require any O proprietary toolkit in order to compile. Although the software is copyrighted, > it is available for free and can be redistributed without fee.
G The ImageMagick image display tool first determines the hardware G capabilities of your workstation. If the number of unique colors in an J image is less than or equal to the number the workstation can support, theQ image is displayed in an X window. Otherwise, the number of colors in the G image is first reduced to match the color resolution of the workstation before it is displayed.
E In addition to the image display program, ImageMagick also has 3 command line programs that perform these functions:
(
6 Describe the format and characteristics of an image(
. Convert an image from one format to another(
+ Transform an image or sequence of images (
@ Read an image from an X server and output it as an image file(
Animate a sequence of images (
2 Combine one or more images to create new images(
@ Create a composite image by combining several separate images(
0 Segment an image based on the color histogram(
< Retrieve, list, or print files from a remote network site
D You can try these and many more functions over the Internet from theD Imaging Machine . Or, youF can see examples of select ImageMagick functions.
: ImageMagick supports many of the more popular imageA formats including JPEG, PNG, TIFF, Photo CD, etc.
G ImageMagick < is known to compile and run on virtually any Unix system and Linux. It also runs underH VMS. SeeA README for compiling instructions.
E ImageMagick is continually being enhanced. Check this section ; periodically to see what enhancements have been added. See O Changelog for past enhancements and bug fixes.
D
Display has a new command< Miscellany->Show Preview. This function allows youF to preview the effects of different image operators at varying scales.D
Display nows supports the DndProtocols for drag-n-drop. M
Added a new format, GRADATION, to gradually pass from one shade B to another (e.g. convert gradation:red-blue shaded.miff).7
A subimage specification can now be disjoint (e.g. image.tiff[2,4,7]).H
ImageMagick no longer requires the XPM library to read or write the XPM image format. N
D I volunteer my time to develop and maintain ImageMagick. However, IB can't do it alone. I am looking for other volunteers to help make? ImageMagick even better. Here is a list of tasks you can do to contribute to this effort:
C
Contribute a binary distribution of ImageMagick for NT, Win95, 3 Unixware, FreeBSD, etc. Let me know if any patches 2 are required to compile on any of these computers.I
Write a program that calls the ImageMagick ReadImage routine 4 and displays the image in a window on the Macintosh.:
Port ReadPICTImage in decode.c to read PICT images on the Macintosh. B
Port ReadPSImage in decode.c to interface with Ghostscript on the Macintosh. H
Improve the ImageMagick documentation. The most useful improvementA would be a HTML section that describes how to perform some of the B more useful ImageMagick functions with actual images to illustrate the results.B
Send me bug reports or any suggestions you have for improving ImageMagick.
