ImageMagick/Rmagick replacement?

Rails
1

Hi, everyone!

I have been recently hit by ImageMagick/Rmagick memory leak issues.
I know I can lesson the problem by manually starting up GC each time
I use Rmagick library but ImageMagick seems to use way too much
memory nevertheless. (on shared hosting setup anyway)

Is there a decent replacement for ImageMagick library? I used to
think ImageMagick was quite efficient because its speed was order of
magnitude faster than pure java image libraries. Is it really a
resource hog, or is it just the way it is with image processing? (I
normally use ImageMagick only for resizing/cropping images, nothing
too fancy.)

I will appreciate any comments or suggestions, thanks!

best,
daesan

Look into MiniMagick: http://rubyforge.org/projects/mini-magick/

Hope that helps !

Thank you Francois for the reply. But MiniMagick also seems to be a
ruby front-end for ImageMagick library, just like RMagick.

The cause of the memory issues seems to be RMagick, unfortunately.
I’ve had lots of such problems, but I’m reluctant to rewrite a big
chunk of my code to use MiniMagick because it seems like a “hack.” Not
to put down MiniMagick, it’s just that I’m hoping RMagick might get
fixed somehow. MiniMagick is just a kind of wrapper that calls
ImageMagick under a separate process, is how I understand it. May be
wrong.

Well what’s the cause of the memory leak? ImageMagick or RMagick? If
it’s RMagick then maybe MiniMagick doesn’t suffer the same leak
problems? I need to figure it out one way or another since I’ve put in
a request with my hosting provider to install RMagick (on a shared
account at that).

So if there are any leak issues and such that may cause problems in my
shared hosting environment I should probably get them to also take a
look at mini magick.

I’ve installed RMagick using the GraphicsMagick library (instead of
ImageMagick) and when using file_column to upload and resize images, i
get serious memory problems too - after the upload, the RAM just fills
up until i kill everything ruby…

Thanks for the link. Very well explained.

Whoa, there seems to be many others suffering from this problem!

Read http://rubyforge.org/forum/forum.php?
thread_id=1374&forum_id=1618 You can lesson the problem by manually
calling GC.start
