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).

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,

Hi, I have a site where I wish to upload a resize a picture, and store it in the file system. The best solution that I have found for this so far is using file_column.

I am using RMagick to convert some files served up by a rails app from tiff''s to pdf''s on the fly. I have Imagemagick installed but was having trouble with some of the conversions.

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.
