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. -- Posted via http://www.ruby-forum.com/.

The initial generation of each image will be a small hit, but page_cacheing makes it snappy after that. class MyControllerNameController < ApplicationController include SuperImagePlugin::Show image_action :show_my_image caches_page :show_my_image end would do the trick. -- Posted via http://www.ruby-forum.com/.

It supports dynamic resizing of images at runtime, and includes options to crop to a specific size. http://mydomain.com/images/123?size=125x125&crop=true I believe file_column only creates the image version when you first upload the image, but SuperImage allows you to dynamically generate what you need. -- Posted via http://www.ruby-forum.com/.

There''s no "versions". Instead, you can specify one initial, optional transformation, using the ImageMagick command-line syntax: file_column :image_field, :magick => "-resize 1000x" And you can specify an arbitrary number of view transformations using: <%=url_for_file_column "model", "image_field", :magick => "-rotate 90 - resize 40x10!" %> -- Kyle Maxwell Chief Technologist E Factor Media // FN Interactive kyle@efactormedia.com 1-866-263-3261
Is Sebastian still maintaining file_column?

i actually got what i wanted. i accomplished it with this in my model:
class Photo < ActiveRecord::Base
file_column :image,
:magick => { :versions => { :thumb => { :crop =>
''1:1'',
:geometry => ''50x50'' },
:medium => { :geometry =>
''400x400>'' }
}
}
end
