For some reason I can''t catch an exception thrown by rmagick inside the app. After an invalid image file is uploaded the process just hangs. I have to kill mongrel and restart to use the app again. img =

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?).

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. Further investigation reveals that the file is in fact invalid because something somewhere is truncating the file path:

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

hi, is it possible to resize animated gifs with file_column? if i upload an animated gif file with file_column than the animation no longer exists... -- Posted via http://www.ruby-forum.com/.

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

The following script creates a search index and then searches it. I get no results? Where am I going wrong?

Hi, Currently I''m using the file_column plugin to upload images and save multiple copies of each at 3 different resoltions: file_column :name, :magick => { :versions => { "thumb96" => "96x150>", "medium250" => "250x400>", "large480" => "480X640>" } } I am wondering if

Hi, Am relatively new to the RoR world. My question is quite simple. I have a query like such: shipmentNumbers = Order.find_by_sql(["select distinct s.id from orders o, line_items li, shipment_lines sl, shipments s where o.number=? and o.id = li.order_id and li.id = sl.line_item_id and sl.shipment_id = s.id", number]) The above query works fine. I wanted to do the same query using

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

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
