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:

I have a file rmg.rb: require ''RMagick'' include Magick cat = ImageList.new("prod.jpg") cat.display exit The file prod.jpg is in the same directory as this file above. I execute the following: ruby rmg.rb I get the following output: /usr/lib/ruby/1.8/RMagick.rb:1377:in `read'': unable to open image `'': No such file or directory:

i have a rails app with a form that allows uploading an image file. I take the image file and read it into rmagick to verify that it''s an image.

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, I''m trying to use the routines on this page: <http://addictedtonew.com/archives/127/rotating-images-with-rmagick-and-ruby-on-rails/> to try and rotate some images. I tried using the script/console to do some testing, - I know ImageMagick is working, as I''m using the filecolumn plugin to resize images as they are loaded. When I try, using the console, to rotate an

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

I''m trying to read image data from an upload file field directly into an RMagick image object without having to temporally save the image file first. Assuming my file field param is assigned to @temp_file, i tried RMagicks from_blob method: img = Magick::Image::from_blob(@temp_file.read) But i get an error message saying that the blob is empty. I also tried feeding it the entire

Hi all, I patched file_column to add imagemagick transformations of uploaded content. I added an options hash, and it takes the :magick and :format keys. :magick is a string of imagemagick command line options for convert (Reference: http://www.imagemagick.org/script/convert.php). Format is an optional extension for the finished image. If Imagemagick recognizes the extension, then it will

Hi there, I''d like to use RMagick to watermark an image in the tmp directory before Attachment_fu saves it to Amazon S3. I took a look at the callbacks available in attachment_fu.

Hi! Is it possible to create a new instance of Magick::Image out of uploaded data via file input? Now i save my file to the disk, then read it to create an instance of Magick::Image, resize it and save it again. -- Posted via http://www.ruby-forum.com/.

Ruby 1.8.4, mini-magick 1.1.0, ImageMagick-6.2.7-0-Q16-windows-dll.exe. I downloaded and installed the mini-magick plugin into my vendor/rails directory. When I try to start webrick it fails, but it does not display any errors. It just simply returns me to the command line. "Ruby script/generate model test" won''t even work. It acts the same way. It doesn''t throw any
