similar to: file_column Trying to Create Thumbnails of Non-Image Files??

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 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!" } },

Hi there, I''m having some problems wityh the :magick options in file_coumn and wondered if anyone else had any similar ones: basically, file_column is working fine for me as is, but whenever I try to do an automatic resize or thumbnail I get the error ''invalid image''. It seems to be a path issue as I get: unable to open image

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

Hello, I''m just starting out with both Rails and Ruby, so I hope this isn''t too simple of a question - but I''ve been struggling to find a solution. I''m using the file_column plugin to handle image uploads and thumbnail generation. In addition, I''ve wrapped the image into a polymorphic table so I can have uploaded images associated with multiple

I am getting this following error when using file_column with RMagick: uninitialized constant Magick /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/ active_support/dependencies.rb:200:in `const_missing'' ./script/../config/../vendor/plugins/rails_file_column/plugins/ file_column/branches/kyle/lib/file_column.rb:621:in `file_column''

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

Has anyone any experiance with the FileColumn plugin. I''m trying to create thumbnails, and also alow non picture uploads. Here''s some working code, but if I try and upload a zip, it says ''File invalid image''. Is there anyway of having both image uploads (and thumbnail generation) while also allowing non image uploads? class Entry < ActiveRecord::Base

Hi, I''m on Windows and getting the following error while trying to use file_column with RMagick, uninitialized constant Magick C:/INSTAN~1.0/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:123:in `const_missing'' #{RAILS_ROOT}/vendor/plugins/file_column/branches/kyle/lib/file_column.rb:621:in `file_column'' I installed file_column by

I''m trying to modify product images when a user marks a product as "sold" and I am able to modify the original image file successfully, but when I try to reprocess the thumbnails, my ImageMagick modifications don''t stick. Here is what I''ve got going so far: def before_save if self.sold_changed? && self.sold? for photo in self.photos

does anyone know much about resizing different versions of images with file_column? i tried it and everything works fine, but my question is can you do more than just make sizes with a version of image? i''m working on a photo album and i would like to resize the image to a medium size, but create a thumbnail as well and crop anything left to make the thumbnail a perfect square. --

Dear all, I have been using file_column for sometime now, and have several pictures which have all been uploaded by file_column. Now, I would like to add more thumbnail sizes for various different purposes -- and perhaps to even delete the sizes I no longer use. Is there a way to do this using file_column automatically? Or can someone please point me out to a script or a hint on writing

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

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

I''m using Attachment_Fu to save several thumbnails of a photo (resizing with ImageMagick) But when I try to crop them, nothing seems to happen to the file I want to drop and no error messages. I check the file timestamp of the thumbnail I want to crop and it looks updated. What''s strange is that ALL the other thumbnails and the original image''s file timestamps are

I''m trying to use file_column in an app I''m writing. Simple file uploads are working fine. However, when I try and use the :magick options to make resized versions, WEBrick dies. This is the Media model: class Media < ActiveRecord::Base file_column :media_item, :magick => { :versions => { :thumb => {:size =>

I have a model called ProductFiles which associates an arbitrary amount of image and documents with a product. I am using the file_column plugin to manage the upload and storage of the images, like so: class ProductFile < ActiveRecord::Base # Accepted MIME types, mime types that are not part of this list are rejected MIME_EXTENSIONS = { "image/gif" => "gif",

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 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. There''s an ''after_attachment_saved'' method but this would be too late, and a ''before_thumbnail_saved'' but this is no good because it''s for thumbnails. I

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,
