Paperclip: How to change "#" modifier behavior?

I use Paperclip 2.3.11 in my Rails 3 application, and I create thumbnails using:

:styles => { :thumb => "80x80#" }

However, if the picture is small, say 32x32, it is enlarged to fit thumbnail dimensions.

I would like to fix that by hac开发者_如何学JAVAking Paperclip.

Unfortunately, I couldn't find the relevant code that describes #'s behavior.

Could you please point me to the right place in Paperclip code ?

Or, maybe there is a better solution ? I would like the thumbnails to be 80x80 unless the original picture is too small (in which case the thumbnail should be the same size as the original picture).

So, # is an argument used by Paperclip to know whether or not you expect the pic to be cropped.

It's written here, through the crop? method, itself looking at geometry[-1,1]: basically the last character of the style you enter.

You could then:

• try what's suggested by @David Sulc which seems ok regarding my previous explanation

• dig further in Paperclip's code and maybe rewrite transformation_to defined here

Did you try :styles => { :thumb => "80x80>#" } ? (Sorry, can't try it out myself...)

You can get more info of the Geometry String which is used by ImageMagick as in following: http://www.imagemagick.org/RMagick/doc/imusage.html
