There are several things you should know about ImageMagick:

1. Unlike the commercial image processing applications, ImageMagick has no graphic user interface. ImageMagick is intended to serve as a command line utility.

2. ImageMagick is powerful. There are hundreds of available methods for creating and modifying images.

3. ImageMagick can be called from Python, Perl, or Ruby via system calls or via language-specific ImageMagick interface modules (i.e., PerlMagick, PythonMagick, or RMagick)

Here is one example of a command line that can be launched from your system prompt, after you've installed the ImageMagick software:

c:\>convert -size 750x500 gradient:gray90-black gradient.png

produces gradient.png, as shown:

Simple, small, graded images are pleasing to the eye and make excellent background images and textures that do not detract from any information that you might want to add to the image.

I'll be posting additional ImageMagick command lines that you might find useful.
