About ImageMagick
ImageMagick is a free software suite developed to create, edit, and compose bitmap images. It supports a huge variety of formats (over 90) including formats like GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and Bézier curves can be added to images and stretched and rotated.
The suite runs on all major operating systems and it can also be used from the command line and it´s command line tools package is one of Linux standard packages, being distributed with many distributions.
Features and Capabilities:
- Convert an image from one format to another (e.g. PNG to JPEG)
- Resize, rotate, sharpen, color reduce, or add special effects to an image
- Create a montage of image thumbnails
- Create a transparent image suitable for use on the Web
- Turn a group of images into a GIF animation sequence
- Create a composite image by combining several separate image
- Draw shapes or text on an image
- Decorate an image with a border or frame
- Describe the format and characteristics of an image
About MagickWand
The MagickWand API is the recommended interface by the ImageMagick team. It is an easy to use programming interface for using the suite.
About MagickCore
The MagickCore API is a low-level interface for ImageMagick.
About PascalMagick
This port is a translation of the c header files for both MagickWand and Magick Core.

Download
PascalMagick 0.1 is available here: http://sourceforge.net/project/showfiles.php?group_id=92177
Status: Incomplete, but usable on both Windows and Linux
Installation
The current version of PascalMagick, 0.1, works on Windows and Linux. Beta testers are necessary for the Mac OS X version.
To start with, install ImageMagick binaries from the official website: http://www.imagemagick.org/script/binary-releases.php
Now download and unzip PascalMagick package (Instructions on the Download section above).
To check that everything is working, open the PascalMagick/wand/wanddemo.lpi project. Now go to the Project --> "Compiler Options dialog" and change the "Other Units" field to point to "../magick", so it can find the PascalMagick/magick/ImageMagick.pas file. After this you can compile and run the test program.
If the program is working, it will load the image.png image located on the same directory as he is, resize it and then save it as a jpg called image.jpg.
One Extra step is necessary on Linux: Rename the image.PNG to image.png due to case issues.
Demonstration program 1
{ Demonstration program for the ImageMagick Library This program was converted from c by: Felipe Monteiro de Carvalho Usage: Just execute the program. It will resize the image.png image on it´s directory to fit (106, 80) and convert it to a jpg.
