Introduction to ImageMagick
ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems.

[Z]ColorMatrix Basics - Simple Image Color Adjustment
This article discusses color operations on digital images, using the new
ColorMatrix
class provided by GDI+. The
ColorMatrix
is a welcome addition to the GDI library, especially with the increase in demand of digital imaging applications, as more and more consumer products are made available. This class, as well as many other new GDI classes, provide more control to the developer and reduce dependence on 3rd party applications such as LEAD tools, and others. Some basic knowledge of matrix operations (multiplication, addition, etc), the RGBA colorspace and GDI+ is assumed.
