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

I''m going to be generating thumbnails from user uploaded images. I''m looking around at the libraries available to do this sort of thing and there are three that look promising.

Hi all, I patched file_column to add imagemagick transformations of uploaded content. I added an options hash, and it takes the :magick and :format keys. :magick is a string of imagemagick command line options for convert (Reference: http://www.imagemagick.org/script/convert.php). Format is an optional extension for the finished image. If Imagemagick recognizes the extension, then it will

Hello, I''m trying to install/update rmagick on a Debian machine using: gem install --local rmagick-2.10.0.gem and get following error: /usr/local/bin/ruby extconf.rb install --local rmagick-2.10.0.gem checking for Ruby version >= 1.8.5... yes checking for gcc... yes checking for Magick-config... yes Warning: Found more than one ImageMagick installation.

I have a file rmg.rb: require ''RMagick'' include Magick cat = ImageList.new("prod.jpg") cat.display exit The file prod.jpg is in the same directory as this file above. I execute the following: ruby rmg.rb I get the following output: /usr/lib/ruby/1.8/RMagick.rb:1377:in `read'': unable to open image `'': No such file or directory:

Hi all i copied rmagic gem in my local system cd rmagick-2.12.2.gem bash: cd: rmagick-2.12.2.gem: Not a directory *[root@localhost shyam]# gem install rmagick --local* Building native extensions. This could take a while... ERROR: Error installing rmagick: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb checking for Ruby version >= 1.8.5... yes checking for gcc...

Tracked down the source of my problem... It seems that Rmagick isn''t properly cropping/resizing GIF or PNG images when uploaded via file_column. I can upload JPG files just fine. Originally I had installed ImageMagick via Debian''s apt-get and built the rmagick gem using "gem install rmagick". This wasn''t working so I uninstalled ImageMagick and tried to

I am using RMagick in my app and am having problems in deployment. The deployment machine (Fedora Core 5) can''t find RMagick unless I change the "require" syntax from that used on the dev machine (OS X). And the dev machine doesn''t like the syntax that works on the deployment server! To wit: [OS X] $ script/console Loading development environment. >> require_gem

Is there a pre-built disk image for rmagic on OSX (including image magic and all the other pre-requisites)? I''ve seen that it comes on the Locomotive image but I don''t want to replace my entire development environment. Does anybody have a sense of how reliable it is on OSX? I''ve seen some fairly negative comments when googling, but that''s not the best way to

I want to install Rmagick on Ubuntu 7.10, but i am getting this error when running gem install rmagick: Can''t install RMagick 2.2.0. You must have ImageMagick 6.3.0 or later. (I installed imagemagick and libmagick9-dev prior to that) I installed rmagick through Synaptic, and it says that i have version 7:6.2.4.5.dfsg1-2ubuntu1 installed (by the way, what does the 7 mean?).

I''m working on a photo gallery and I''m using File_column to handle the uploads of the files and create my thumbnails, but does anyone here have any idea how to have a watermark (opaque text maybe) placed over one of the versions? Any ideas on how to go about this would be great. Even if it''s just straight RMagick code, that would be fine too. Thanks in advance for the

Hello all. I''m a seasoned system administrator and have no fear of building source packages on a variety of platforms, but RMagick has, until recently, evaded all of my attempts to building it on my PowerBook. Someone else just mentioned that they had trouble with RMagick on OS X (Intel, don''t really know if my advice will help) so I decided to post a HOWTO to the list. I

hi guys, I have been trying to install Rmagick on ubuntu karmic koala for a day. Yes, ImageMagicK has already been installed and works great with paperclip and a few other perl scripts I have (which uses Image::Magick). The following is what the execution looks like when I tried to install rmagick ( " gem install rmagick" ): -------------------- Extract start

I''m looking for a way to give the user a progress monitor on large image manipulations with RMagick. I first looked at this method - http://www.imagemagick.org/RMagick/doc/imageattrs.html#monitor - to do it in a controller action, but since I can''t call multiple renders in an action, I would need to store the progress in the database and call another action from javascript to

I''d like to implement a system in a Rails app where I allow the user to upload an image file, and then the app takes that image and manipulates it, saving a thumbnail, small, and original size version of the file to the server. How would I go about doing that? Thanks, Jeff -- Posted via http://www.ruby-forum.com/.

I read the 13th recipe in the book "Rails Recipes" from Chad Fowler. I install with gem the gruff-library (gem install gruff). After the installation, I download the "rmagick-win32-1.13.0_IM-6.2.9-3.zip" file and install it on my win32-machine. It was successfully! So, I create a controller with script/generate. In a method, which I wrote after the creation, I''ll make

Hi all, I''ve been trying to install GraphicsMagick with RMagic. I''ve tried ImageMagick with RMagic as well. I''ve tried the installations using Darwin Ports, Gems and from source.

I know that Zed has made mention of the fact that using RMagick with mongrel and rails is a bad thing. I''m currently using FlexImage (which in turn uses RMagick) on my application and really haven''t had too many problems. We get a restart for memory usage every 8-10 hours on one mongrel of twelve running, but I''m not sure if that''s an RMagick issue. Either way,
