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:

Cheers.
