attachment_fu -- specify exact resize value

How can you get the images and thumbnails to resize to an exact demension? This is what I have in my model:

:resize_to => '150x150>', :thumbnails => { :thumb => '31x31>' }

If the images are not perfectly squared, I get sizes like 31x23 or 112x150. I guess I would need the image to be cropped to become exactly 31x31. Any suggestions?

Thanks in advance!

You can remove the ">" at the end there or use an array [31, 31] instead and it will squish the image to the size you want.

Cropping is not yet supported in the stable release of attachment_fu... but if you are willing to do some editing in attachment_fu .rb files here is a link so someone who claims they found a solution:

Also here is something I found through a quick Google but I'm not sure if it's any good either:
