I recently integrated Kropper into a RoR application. A fundamental  
flaw in the upload-save-crop-save process used by Kropper is that  
attachment\_fu automatically scales down the image on first save  
to :resize\_to dimensions. After the subsequent crop-which may result  
in a significant drop in resolution-the image is scaled back up  
to :resize\_to dimensions: an ugly lossy operation.

The attachment\_fu\_skip\_resize plugin gives attachment\_fu the ability  
to temporarily bypass resizing of the full-size original image, thus  
allowing your final cropped photos to be of the highest quality as  
possible.

It’s a quick monkeypatch. Hope someone finds it useful 🙂

Yes, I do! But I can’t load your plugin, your ssl server seems to have  
a broken certificate ☹

Do you have another download link?

It’s not actually broken… just self signed. The public URL is…  
[https://svn.openrain.com/opensource/public/rails/plugins/](https://svn.openrain.com/opensource/public/rails/plugins/)  
attachment\_fu\_skip\_resize/

Coincidentally, I gave a presentation yesterday night to the Phoenix  
Rails group on this stuff: attachment\_fu, Kropper,  
attachment\_fu\_skip\_resize, Rmagick, and what we’re doing with it all  
for the face-based searching the computation services behind  
(upcoming) [Mugr.com](http://Mugr.com). Slides and audio links are available on my blog,  
here…
