I''ve based my code on the Agile example for uploading files, pages 362-365. I''ve successfully loaded the Picture object to the database, but I come unstuck when trying to replicate this for a thumbnail version of the original image: thumbnail = Thumbnail.new thumbnail.name = ''thumbnail_'' + @picture.name.to_s

Hello, I had a problem cropping images with file_column. These are my settings: file_column :image, :magick => { :versions => { :thumb => "80x80>", :medium => "150x150>", :square => { :crop => "1:1", :size => "50x50!" } },

RMagick Image Rendering I am fairly new to Ruby on Rails and I have been trying to upload images and create thumbnails using the "Processing Uploaded Images" recipe from the Rails Recipes book. The script uses RMagick to create thumbnails of the uploaded images and saves both the uploaded images and the thumbnails in the public/uploaded_images directory. However when I upload an image,

Hi, I am using rmagick to resize a copy of uploaded images and display the copy as a thumbnail. Once the upload is processed it redirects the user to a page that should display the thumbnail to the user. The problem is that the rmagick resize function seems to keep going in the background after handing the new images url (and control) back to rails, which then happily renders the page with

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, 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. This was working great, for about an hour, but all of the sudden I began to get the following error (only when i attempt to resize). NameError (undefined method `assoc'' for class `Magick::ImageList''):

Hi, I''m using acts_as_attachment to create thumbnails in a filesystem (no problem there), but I''m having a rough time figuring out how modify the image to crop it, and then put it back into the filesystem. I think that I can pull the image OK and modify the Image OK with RMagick. So really I just need a pointer on putting it back into the filesystem as a modified thumbnail,

Hi, I''m brand new to RMagick (and pretty new to Rails for that matter!). Right now, site owners are allowed to upload product and ingredient photos to the website. Everything works great, ingredients are sized down and proportioned correctly...the problem is that the resulting images are so blurry! So I''ve been doing some research and it looks like Paperclip::Processor may be the

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,

I see that the SVN version of the excellent file_column plug-in can create thumbnails using the url_for_image_column helper. This uses Rmagick to create the thumbnail... Quick question... Let''s say the file is a TIFF image - can the helper create a JPG version of the thumbnail for display in the browser? Curious if the plug-in can handle that transform with some creative use of the

Hello ~ I have RMagick and file_column working in RoR. In my model I am setting up some standard sizes for the submitted photos. The photo files are created and named correctly, but the sizes are wrong. Only the second argument of my geometry call is used, with the width dimension being resized proportionately. file_column :image, :magick => { :versions => { "medium" =>

Am having trouble with file_column -- on certain crop operations, it says: A TypeError occurred in [controller]#[action]: can''t convert Magick::GravityType into Integer [RAILS_ROOT]/vendor/plugins/trunk/lib/magick_file_column.rb:90:in `crop'' Any advice?

Hello, Recently attachment_fu stopped resizing images for me. I''m puzzled because before today it was resizing them and I don''t know what''s changed. Here''s my code: class Product < ActiveRecord::Base has_attachment :content_type => :image, :storage => :file_system, :max_size => 18.megabytes,

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.
