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

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, I''m using the basic magick features of file_column, and while files are uploading fine without the magick options, as soon as I do something like :magick => { :size => "400x600" } I get an ''invalid file'' error.

Hi, I need to take a single uploaded image file and save three resized versions of it, a thumbnail, normal and large version. I was planning on doing this in my model by having an array of geometry strings and looping through them, each time saving a new image object resized to the correct geometry. I know that file column does similar stuff, but I would prefer to have a separate database row

So ive recently finished up my first RoR application and made sure it all worked right on the windows machine i developed it on. then deployed it on GeekISP.com which runs Open/Free BSD. I had to jump through a few little hoops to get it working and set the permissions for file_column to create directories, but it still doesnt work right. When i go to add a new item to the database and try

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.
