Rails - Jul 2009 - attachement_fu width and height ratio

Hi there

I am wondering on how can i thumbnail the pictures height and width
based on ratio

let''s say that my design is limited to a fixed size. and I want to
keep the image looks nice and not stretched. e.g. the width is 200 and
the height is 200

in case that i have an image that is tall, it will break the design. I
am looking for a way on how to check which is bigger the width or the
height and based on that make the thumbnail

Thanks

IIRC, the resize option of
:thumbnails => { :thumb => ''100x100>''}

keeps the aspect ratio (at least with Rmagick / Imagemagick)...
1024x768 becomes roughly 100x75, while 500x768 becomes roughly 65x100.
