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.

10	+
11	+	- Convert an image from one format to another (e.g. PNG to JPEG)
12	+	- Resize, rotate, sharpen, color reduce, or add special effects to an image
13	+	- Create a montage of image thumbnails
14	+	- Create a transparent image suitable for use on the Web
15	+	- Turn a group of images into a GIF animation sequence
16	+	- Create a composite image by combining several separate image
17	+	- Draw shapes or text on an image
18	+	- Decorate an image with a border or frame
19	+	- Describe the format and characteristics of an image

51	+	### Download
52	+
53	+	PascalMagick 0.4 is available here: <http://sourceforge.net/project/showfiles.php?group_id=92177&package_id=174103&release_id=431432>
54	+
55	+	Status: Magick Wand headers are complete and working on both Windows and Linux.
56	+
57	+	### Instalasi
58	+
59	+	The current version of PascalMagick works on Windows and Linux. Beta testers are necessary for the Mac OS X version.
60	+
61	+	To start with, install ImageMagick binaries from the official website: <http://www.imagemagick.org/script/binary-releases.php>
62	+
63	+	Now download and unzip PascalMagick package (Instructions on the Download section above).
64	+
65	+	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.
66	+
67	+	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.
68	+
69	+	One Extra step is necessary on Linux: Rename the image.PNG to image.png due to case issues.
70	+
71	+	### Demonstrasi program 1
72	+
73	+	{
74	+	Demonstration program for the ImageMagick Library
75	+
76	+	This program was converted from c by: Felipe Monteiro de Carvalho
77	+
78	+	Usage: Just execute the program. It will resize the image.png image
79	+	on it´s directory to fit (106, 80) and convert it to a jpg.

138	+	svn checkout <http://svn.freepascal.org/svn/fpc/trunk/packages/base/imagemagick> imagemagick
139	+
140	+	You can also download the full fpc 2.1.1 repository and it will be included.
141	+
142	+	### Bug Reporting/Feature Request
143	+
144	+	Tests are necessary to verify if the bindings work with all versions of ImageMagick.
145	+
146	+	You can post Bug Reports / Feature Requests here:
147	+
148	+	------------------------------------------------------------------------
149	+
150	+	Bug 1
151	+
152	+	There is an error in pixel_iterator.inc The correct declaration is function NewPixelIterator(wand: PMagickWand): PPixelIterator; cdecl; external WandExport;
153	+
154	+	also the following declarations should be added function PixelGetNextIteratorRow(iterator: PPixeliterator; var wandCount : Cardinal) : PPPixelWand; cdecl; external WandExport;
155	+
156	+	function PixelGetPreviousIteratorRow(iterator: PPixeliterator; var wandCount : Cardinal) : PPPixelWand; cdecl; external WandExport;
157	+
158	+	Cheers, Todd.
159	+
160	+	Status: Fixed on 0.3
161	+
162	+	------------------------------------------------------------------------
163	+
164	+	Bug 2
165	+
166	+	There is a problem in "magick_wand.pas" and "ImageMagick.pas": the compiler option "{\$PACKRECORDS C}" must be in the "{\$ifdef FPC}\[...\]{\$endif}". Otherwise the units do not compile with Delphi (Delphi 7 in my case).

169	+
170	+	------------------------------------------------------------------------
171	+
172	+	Bug 3
173	+
174	+	your definition of "MagickGetImagePage" in magick_image.inc:
175	+
176	+	function MagickGetImagePage(wand: PMagickWand; width, height: PCardinal; x, y: Integer): MagickBooleanType; cdecl; external WandExport;
177	+
178	+	correct definition (x and y are "PInteger"!):
179	+
180	+	function MagickGetImagePage(wand: PMagickWand; width, height: PCardinal; x, y: PInteger): MagickBooleanType; cdecl; external WandExport;
181	+
182	+	Best wishes, Marc Geldon ([PRO IT SYSTEMS](http://www.proitsystems.de))
183	+
184	+	------------------------------------------------------------------------
185	+
186	+	Bug 4
187	+
188	+	ImageMagick 6.2.7 (don't know exactly what version) introduced a few changes in MagickWand record and others. Also, a few variable definitions were incorrectly declared, and some function imports missed the "cdecl", so they didn't work (like NewMagickWand()). I've fixed all this issues. Can I upload the changes somewhere?
189	+
190	+	Best regards, Arcnor
191	+
192	+
193	+	Hello, you can send it to me, and I´ll apply the changes. My e-mail is felipemonteiro.carvalho@gmail.com By the way, did you correct bugs 2 and 3 also? thanks a lot --Sekelsenmat 05:07, 8 June 2006 (CEST)

195	+	------------------------------------------------------------------------
196	+
197	+	Bug 5
198	+
199	+	MagickNewImage parameters convention is cdecl.
200	+
201	+	Correct definition of MagickNewImage in magick_image.inc:
202	+
203	+	function MagickNewImage(wand: PMagickWand; const columns, rows: Cardinal;
204	+	const background: PPixelWand): MagickBooleanType; cdecl; external WandExport;
205	+
206	+	------------------------------------------------------------------------
207	+
208	+	Bug 6
209	+
210	+	MagickCompositeImage : Composite_wand is a PMagickWand constant.
211	+
212	+	Correct definition of MagickCompositeImage in magick_image.inc:
213	+
214	+	function MagickCompositeImage(wand: PMagickWand; const composite_wand: PMagickWand;
215	+	const compose: CompositeOperator; const x, y: Integer): MagickBooleanType; cdecl; external WandExport;
