Just a small update on the ImageMagick front! First of all, a reminder. All my ImageMagick related efforts (compiler script + test project) can be found over at github.

The latest ImageMagick, at the time of writing is version 6.6.8-5. I’ve bumped the versions of the delegate libraries, as well:

• jpeg: 8-c
• png: 1.4.5
• tiff: 3.9.4

Finally I’ve got my hands on the latest Xcode4 and on the latest iOS4.3 SDK. I’ve updated the IM_Test Xcode project on the same git repository of the compiler script :)

You can always grab the pre-compiled versions from ImageMagick’s FTP stite

I hope everyone is happy about the update, if you are let me know what you’re up to with ImageMagick on the iPhone and if you feel like don’t hesitate in donating (link on the right), as you can see this blog runs ads-free and any bit helps!

Cheers!

Hi,
I’ve compiled the latest ImageMagick for iPhone with the usual png/tiff/jpeg compatibility. Everything is compiled so that it shouldn’t be rejected by Apple. Please let me know if that’s the case.

You can find the latest 6.6.1-5 version here:IM 6.6.1-5
Or if you dare the latest beta 6.6.1-6 here:IM 6.6.1-6

As usual you can find the latest updated working XCode project here:IM_Test project

I’m in talks with the developers of ImageMagick to try and have a “standard” build for iPhone so that everyone can just go there. I will keep you up to date with it.

Please report any issues you might have and especially if now the applications will be accepted by Apple!

Regards,

~C

1.5.2010 – UPDATE: for the latest compiled libraries and test project please refer to: Latest ImageMagick

Hi all ImageMagick developers!

It has been a long time since my last update to my script for building ImageMagick and having it running as a statically compiled library so that you can use it in all your iPhone applications! To make up for the delay I have made some improvements:

• Script now working on Snow Leopard (tested on 10.6.2 against iPhone SDK 3.1.3)
• Script better organized (although I want to make it even better!)
• Script available through github, so if you want to help me updating it, know some bash scripting, and willing to help, just contact me!
• Updated libpng to v1.4.0 and libtiff to v1.9.2

As usual I also link you a .zip containing all the .a universal (iPhone + iPhoneSimulator) libraries that you can use right away in your projects! I’ve also updated the test project, just minor changes, and the new libraries!

I hope you are happy with the update, and I would like to thank:
Verdier Christophe for a much better script stub posted in the comments
Cocoawithlove.com for a good guide on understanding why the heck the iPhoneSimulator libraries weren’t working at all!

Don’t be shy and comment, also pointing me to some cool iPhone Apps that you’ve been working on that use ImageMagick!

PLEASE READ THE UPDATE

Here I go again with an update to the ImageMagick on iPhone saga.

As requested by a few people here on the site, I’ve added TIFF functionality to the compiled library. If you’re interested in reviewing the all process to compile ImageMagick for the iPhone please refer to my two previous posts where that’s described in detail: first and second.
TIFF is compiled with ZIP functionality, so you can compress your TIFF files.

As usual I’ve provided you with an updated script which now enables the compilation of tiff-3.8.2 alongside jpeg and png to have it supported in ImageMagick.

For the lazy there’s always the compiled static libraries and includes. But remember to take as well the *.xml configuration files for some ImageMagick functionality!

And the IM_Test Xcode project has been updated as well where the TIFF functionality is tested.

I guess I’ve updated everything accordingly. Please let me know if anything isn’t working for you. As usual contacting me here on the site.

I’ve added to the project a simple benchmark, consisting in running the MagickWand creation, filtering and destruction a given number of times (customizable in the beginning of the source file, for instance 10), calculating how long it takes each time and in total.

The results are impressive, and can be better exaplined by looking at this simple graph:

Benchmarks running on the simulator and on the device (click to see better!)

As you can see working with uncompressed data achieves 3x faster results on the iPhone device, with a mean running time of 0.85 seconds to run an ordered posterize filter on an image of size 320×460 (the size of the iPhone screen). Similar results are also on the Simulator achieving 3.7x faster filtering for the same image.

The end line is trivial, working with uncompressed data, while being less easy (but as you can see from the project code not extreme) or intuitive yields much faster results!

You can download a better looking graph and the IM_test project as usual.

For any comment don’t hesitate to write, as you’ve seen I try to pick up my comments as much as I can (even on holiday!)

Thanks goes again to Karl who’s has the idea of working with raw images, and provided with the code to achieve so.
