I've just uploaded RMagick 1.12.0 to RubyForge. This version fixes an API incompatibility with the Image#level method that I introduced in version 1.11.0. Thanks to Al Evans for reporting it and helping me find a fix.
If you plan on installing this version with RubyGems please read the Release Notes (http://rubyforge.org/frs/shownotes.php?release_id=5551) before installing this release.
If you're using a web hosting service and it has a very old version of RMagick installed, please consider asking your service provider to upgrade. I've fixed several memory leaks in recent releases so if you're running into memory usage problems with your web app upgrading could really pay off.
RMagick is available as always from RubyForge: http://rubyforge.org/projects/rmagick/.
RMagick is an interface to the ImageMagick (www.imagemagick.org) and GraphicsMagick (www.graphicsmagick.org) image processing libraries. RMagick supports more than 90 image formats, including GIF, JPEG, PNG. It includes RVG, a 2D drawing API. RMagick comes with comprehensive HTML documentation.

RMagick installed, please consider asking your service provider to
upgrade. I've fixed several memory leaks in recent releases so if you're

Thank you for that. Fixed our memory usage problems that I was just in
the process of narrowing down to the library. Beat me to the punch!

Hi,
I'm having a problem with RMagick. Somehow "number_scenes" stopped working for me.
Background: I'm on a Mac and mainly use Locomotive, a self-contained ruby/rails installation, which basically relies on binaries built using darwinports, a packet manager which builds from source.
When using an older Locomotive version on PPC, I get the expected results:
>> ::Magick::Image.read("/Users/admin/a.pdf").size
=> 5
>> ::Magick::Image.read("/Users/admin/a.pdf"){self.number_scenes=1}.size
=> 1
This older version uses ImageMagick 6.2.4 and RMagick 1.9.3.
A newer version of Locomotive uses ImageMagick 6.2.6 and RMagick 1.10.1. Here I get broken behaviour:
>> ::Magick::Image.read("images/a.pdf").size
=> 5
>> ::Magick::Image.read("images/a.pdf"){self.number_scenes=1}.size
=> 5
I did a fresh install of Ruby 1.8.4, ImageMagick 6.2.7-5 and RMagick 1.12.0 using darwinports and could verify the same broken behaviour.
Maybe related: I got the following output during installation of the native extensions of RMagick 1.12.0:
magick/cache.c:2385: failed assertion `cache_info->number_views != 0UL'
I'm totally clueless how I can furter investigate that problem. Any hints?
Thanks,
Timo

That's good news! I ran all my tests with valgrind (http://valgrind.org/\) and they're coming up clean. If you think you're having a problem with a memory leak in RMagick give me a shout and we'll work on it.

I reproduced this problem on my Powerbook. It looks like a problem with ImageMagick. I've emailed the IM developers for help. If you open a bug track in the RMagick project on RubyForge it'll help me track this problem and keep in touch with you.
http://rubyforge.org/tracker/?atid=133&group_id=12&func=browse
Forgot to mention, that I'm now on Intel. The test which showed the expected behaviour was on PPC. Did you verify on Intel or PPC? (At least I call my MacBook Pro still PowerBook sometimes...)
I just submited a Ticket.
Thanks for your immediate help!

Just tried it: Doesn't matter if it's on Intel or PPC.
