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.

Try SuperImage instead. 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](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.

As long as you use cacheing there will be no difference. 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.

how is this on speed? i’m working on a site that has high traffic loads  
so i think i would rather have the images already generated beforehand.

Is Sebastian still maintaining file\_column?

Do you see any potential to merge your versions or take over  
development?

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

[http://svn.kylemaxwell.com/file\_column](http://svn.kylemaxwell.com/file_column) (my file\_column branch).  
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!" %\>
