Hello, I''m having some trouble with opening files with ImageMagick, by way of RMagick, from within Rails. When trying to open an existing image, I get this error: "Corrupt JPEG data: premature end of data segment: " My code is pretty straightforward: pic = Magick::Image.read(filename) I can view the image in question through the browser, so I don''t think

Hi all, I''ve been trying to install GraphicsMagick with RMagic. I''ve tried ImageMagick with RMagic as well. I''ve tried the installations using Darwin Ports, Gems and from source. Nothing seems to work properly. My specs: ruby --version ruby 1.8.4 (2005-12-24) [powerpc-darwin8.5.0] rails --version Rails 1.1.0 convert -version Version: ImageMagick 6.1.8 04/05/06 Q16

Is there a pre-built disk image for rmagic on OSX (including image magic and all the other pre-requisites)? I''ve seen that it comes on the Locomotive image but I don''t want to replace my entire development environment. Does anybody have a sense of how reliable it is on OSX? I''ve seen some fairly negative comments when googling, but that''s not the best way to

I''ve based my code on the Agile example for uploading files, pages 362-365.

Everything works like a charm locally, but running in production (Dreamhost shared with Passenger if it matters), "These gems that this application depends on are missing \n -rmagick" Rmagick is installed on dreamhost, but I have also copied the gem into the vendor directory, so it''s not even found within it''s local files. I''m using config.gem

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 need a way to upload an image and display it without using any of the plugins that use rmagic. I have used the plugins (file_column, fleximage) which both use rmagic and gave me problems (never got fleximage to work) Thanks in advance - K --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails:

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

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

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,

Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database. The idea is that after awhile people will be able to search based on camera make, model, lens settings, etc... and all the pictures that meet those requirements will be displayed. The picture is stored on the file

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
