ImageMagick overview
ImageMagick is a robust collection of UNIX tools and libraries offered under a usage license to read, write, and manipulate an image in many image formats (over 89 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, or from the C, C++, Perl, Java, PHP, Python, or Ruby programming languages. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. ImageMagick's focus is on performance, minimizing bugs, and providing stable APIs and ABIs.
Here are just a few examples of what ImageMagick can do:
- Convert an image from one format to another (e.g., TIFF 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 images
- Draw shapes or text on an image
- Decorate an image with a border or frame
- Describe the format and characteristics of an image

Version: 6.8.8
ImageMagick is free, which is great! However, I consider it to be geek-ware. If you visit the developer's page you'll find they recommend installing it via MacPorts, which uses X11, which requires Apple's developer software Xcode to build the plugin from the source code provided. You don't just casually jump into X11 stuff. The learning curve is a bear.
To go along with the geek-ware-iness: There are TWO version numbers on this software. One is '13.0.0' which refers to I know not what. The other is '6.8.7', which is what actually is downloading today, NOT '6.8.8' despite that version being available for Linux, etc.
Summary: Be prepared to go geek with this software.

Version: 6.7.9
Sorry, posted as comment by mistake.
Been using this under Lion. Upgrade to Mountain Lion breaks it
dyld: Library not loaded: /ImageMagick-6.7.9/lib/liblcms2.2.dylib
Referenced from: /Users/mikel/lib/ImageMagick-6.7.9/bin/convert
Reason: image not found
fresh install does not help

Version: 6.7.9
Use this fine under Lion (10.7). Upgraded to Mountain Lion (10.8.2) and now I get
dyld: Library not loaded: /ImageMagick-6.7.9/lib/liblcms2.2.dylib
Referenced from: /Users/XXX/ImageMagick-6.7.9/bin/convert
Reason: image not found
tried fresh install - no luck.

Version: 6.7.7
Today is the 2nd of June, 2012 -
The Mac OS binary distribution of ImageMagick seems to be stuck on release 11.3.0 (tar package contains version 6.7.5 from back in Feb of 2012). MacUpdate is displaying/linking to a 'Version 6.7.7', but the download contains version 6.7.5.
I contacted the 'Wizards' at imagemagick.org. If they provide a link to a more recent release, I'll post it here.
May 29 2012
Version: 6.7.7
30 May and newly posted "version 6.7.7" still provides Release 11.3.0, containing "version 6.7.5".
May 22 2012
Version: 6.7.7
The link provided on MU for "version 6.7.7" actually provides Release Version 11.3.0, which contains "Version 6.7.5" which, like every second release recently, gives a Library Exception error (at least on Lion). I'm stuck on 6.7.3, which works.
The MacPorts updating system is much more reliable, but requires about 4Gig of complex interlinked dependencies to allow the 4Mb of executables to function. My poor little SSD drive can't spare that space.

Version: 6.7.1
Haven't tried this on Lion but on Snow Leopard I get "Incompatible library version: convert requires version 10.0.0 or later, but libltdl.7.dylib provides version 9.0.0" when I try to run 'convert'.

Version: 6.5.5
Probably a better way of installing this is Macports. I've never had any problems that way, and it keeps me on top of the frequent updates.

Version: 6.5.5
I never use precompiled binaries but try to compile them by myself which allows to add different tools. Lately I was able to compile IM 6.5.5-7 with jbig2 and autotrace
One definitely should not compare CLI of ImageMagick with click interface of Desktop publishing tools as they are different programs used for different tasks. It does not mean that Photoshop cannot do some batch jobs or one can write a GUI using (some) of the features of IM.
There are tasks which simply can have no reasonable GUI except drag-and-drop. Example? autotrace or potrace converting bw bitmap graphics to a vector one. Another? pdfcrop (not part of IM but TeX distribution) which by default crops according to bounding box. There is no controversy CLI vs GUI and depending on the task I use one or another

Version: 6.5.5
current link is not to correct version 6.5.5...instead it links to 6.5.3
apparently the new 6.5.5 is only for windows at present and MU is mis-informed :(

Version: 6.5
Is it just me or does it seem odd to use a CL tool to do GRAPHICAL work? Wouldn't a GUI be easier?

Version: 6.4.5
I WISH SOMEONE WOULD CREATE A GUI
This software seems extremely useful but, unfortunately, many of us are not familiar with UNIX and Command Line Interface.

Version: 6.2.3
The simple reason we need ImageMagick is that other platforms rely on it heavily. Having it on OS X as well makes things easier for a lot of people, and helps improve compatability between platforms.

Version: 6.2.2
Command line tools are good. But I don't see why we need ImageMagick while Mac OS X Panther has SIPS. I am not a developer but I did write a short shell script with SIPS and it works fine. I still don't see what additional functionality ImageMagick brings to a Panther user.

Version: 6.2.2
Hey Kids,
This software package is meant for developers. You know, "Developers! Developers! Developers! Developers!" like the scary ape-man from Microsoft said. People who write software.
I write a web-based app that allows its users to upload images, and thanks to ImageMagick, they can resize, crop, and scale the pictures without having to have a desktop program to do this.
The techniques involved are very similar to something another guy came up with, that actually uses ImageMagick on its backend: http://codebehind.dk/scale_crop/
I write my program on my iMac, the same machine I also use Photoshop on. Isn't life grand?
I, for one, am glad to know a new version of ImageMagick available, even though the only clicking involved is, um, firing up the terminal.
And I say that as a 15+ year Mac user.
Apr 25 2005
Version: 6.2.2
We don't need command line, we need clicks! Thats the way that MacOSX schould go!
Command line is a step back in the Computer history!
The best at this tool is that the tool is free.
There are many other tools that works faster and are "easy to use" like Graphic converter, Batchfoto or Sizerox.
I don't give this tool stars cause the developer has done his job.

Version: 6.2.2
What is the difference between ImageMagick and SIPS? I don't see any additional functionality in ImageMagick not available in SIPS... Or have I missed anything?
