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

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''ve tried migrating acts_as_attachment to attachment_fu (just to see if I could replace RMagick with ImageScience+FreeImage), but the quality of the thumbnails is just horrendous, blurred beyond recognition (downscaling a 1280x1024 to a few considerably smaller thumbnails). Changing attachment_fu to use RMagick again and the thumbnails were crispy sharp again. I was wondering

Hi, which is the best way to upload an image, keep that and also make a thumbnail? The images should not be stored in the database, but as normal image files in a specific directory. I think that for the thumbnail i should use rmagick, but for the upload ? (something which work with and without javascript, in every browser) Thanks :) -- Posted via http://www.ruby-forum.com/.

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,

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 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

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

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

Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it.
