version 3.7.5, is a package for display and interactive
manipulation of images for the X Window System. It is written in C and
interfaces to the X library, and therefore does not require any
proprietary toolkit in order to compile. Although the software is copyrighted,
it is available for free and can be redistributed without fee.
The ImageMagick image display tool 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.
In addition to the image display program, ImageMagick also has
command line programs that perform these functions:
You can try these and many more functions over the Internet from the
Imaging Machine . Or, you
can see examples
of select ImageMagick functions.
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
Combine one or more images to create new images
Create a composite image by combining several separate images
Segment an image based on the color histogram
Retrieve, list, or print files from a remote network site
ImageMagick supports many of the more popular image
formats including JPEG, PNG, TIFF,
Photo CD, etc.
is known to compile and run on virtually any Unix system and
Linux. It also runs under
README for compiling instructions.
ImageMagick is continually being enhanced. Check this section
periodically to see what enhancements have been added. See
Changelog for past enhancements and bug fixes.
- ImageMagick no longer requires the XPM library to read or write the
XPM image format.
- Join the ImageMagick mailing list. Send subscribe magick
- There is a limited capability version of ImageMagick for the
- ImageMagick is now fully ANSI C compliant and will compile with any
C++ compiler. K & R compilers will no longer compile ImageMagick.
- You can now compile ImageMagick on Posix systems without the X11
libraries. Use the
X11 Stubs libraries instead.
- You can now make an animated GIF loop within Netscape 2.0. For further
details see Frequently Asked Questions .
- The new option -adjoin concatenates information found in multiple
input image files and writes it to a single multi-image file.
- Use convert to create MPEG images.
- All LZW compression has been removed because it is subject to
licensing and is not freely distributable. See
Frequently Asked Questions for details.
I volunteer my time to develop and maintain ImageMagick. However, I
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:
- Contribute a binary distribution of ImageMagick for NT, Win95,
Unixware, Dec Alpha, FreeBSD, etc. Let me know if any patches
are required to compile on any of these computers.
- Write a program that calls the ImageMagick ReadImage routine
and displays the image in a window on the Macintosh.
- Port ReadPICTImage in decode.c to read
PICT images on the Macintosh.
- Port ReadPSImage in decode.c to interface with
Ghostscript on the Macintosh.
- Improve the ImageMagick documentation. The most useful improvement
would be a HTML section that describes how to perform some of the
more useful ImageMagick functions with actual images to illustrate
- Send me bug reports or any suggestions you have for improving
The source distribution of ImageMagick as well as pre-compiled binaries are
