similar to: file_column: Complex image processing with Rmagick

I am new to RoR. I am trying to use file_column and rmagick to resize images uploaded to my RoR app. The problem is that only images larger than the dimensions specified in my code will resize. For instance, if the uploaded image is 98x98, then the new images will remain that size. How can I enlarge images using file_column and rmagick? Here is the code in my model: file_column

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, 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

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''):

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" =>

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!" } },

I''m using file_column 0.3.1 and I recently installed RMagick on my machines, so I''m adding the :versions resizing functionality to my models. I quickly noticed that resized versions are only being created for newly uploaded images, and that no magicked versions get created for existing images. I thought file_column would be smart enough to generate :versions as needed. Has

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. --

Howdy. We use the handy file_column plug-in in some of our apps. We have a model with a file field and we upload both images and non-images into this field. It is specified as follows: file_column :file_uri, :magick => {:versions => {:thumbnail => {:size => ''200x''}}} Well, it works great for images but for non-images, the save fails. The root cause is an

I got a strange problem. My image upload worked fine in my XP. However after deploying to Linux, I am not able to upload images from XP machine - I get "Image location invalid image" error message. However, I am able to upload images from linux boxes. Can anyone tell me what would cause this problem? Is there any setting in file_column that are specific to the deployment server os?

Tracked down the source of my problem... It seems that Rmagick isn''t properly cropping/resizing GIF or PNG images when uploaded via file_column. I can upload JPG files just fine. Originally I had installed ImageMagick via Debian''s apt-get and built the rmagick gem using "gem install rmagick". This wasn''t working so I uninstalled ImageMagick and tried to

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

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''ve been using file_column for a while and it''s the best thing since sliced bread. But there''s one thing that it doesn''t do that seems like it''d be a pretty useful feature. For an app I''m working on I really need to know the dimensions of the store image in my view (and in general it''s always good to have the dimensions in your

i want to upload and resize images so i installed the file_column plugin but im having a big trouble, i have a table images with (id, name) fields where the images names/path will be stored, i get a success message(from the controller after @art_image.save) every time i try to upload but only a blank directory its created /public/image/name/tmp , without errors messages, i see a post related

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

Hi guys, I want to have a file upload form which would allow the user to ask for certain transformations of the image before saving it - most importantly, to resize it. Now, how can I make an instance of FileColumn enabled model process these imagemagick instructions? My model looks looks somewhat like : class Image < ActiveRecord::Base attr_accessor :resize_dimension, :resize_to

Hi everyone, I have a photo site that I''m making and I''m using file_column to handle the auto-generation of several "version" of each photo: essentially thumbs and fuller-sized version. The full sized versions retain the original''s proportions, whereas the thumbs are all 4:3. This means most of the thumbs are cropping the original. This all works great, but I
