As most of your know ImageMagick is like the photoshop on your console demand. Best with their explanation.
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.
It is very powerful and supports all platforms with tons of different languages and implementations. Because my hosting solutions did not suppot it (many of them dont do as well) I always used awesome GD library to process images on my projects. Well now my hosting does support and I am going to use it so I needed to install it to my development environment which is windows. I am going to install and use Imagick also because using IM from native PHP is much more faster than using it from console via exec.
Well first of all ImageMagick on windows with PHP is a really pain in the ass, if you have the commitment and time go for it otherwise use it from console. Here are the steps and todo's to install for PHP 5.2.x, ( I dont know if it works with PHP 5.3.x or below, you will need to test for yourself. I am a happy camper for now ).
Just to make things clear, all the PHP dll files (librarires) are 32 bit, so if your system is 64 bit and you will still need to download and operate 32 bit ImageMagick, Apache, etc.
