Thanks for this. In fact I just needed to find the dimensions of my images, but your code proved very helpful - I modded it to just return the dimensions. I made an entry in my blog ( http://pennysmalls.com ) with the code.

Justin: Of course... it was actually super 'fascinating' .

Mak: Ha. I'm using it in a little merb app and it's so much faster than imagemagick. In fact, here ([attachment_pu.rb](http://blog.new-bamboo.co.u... is the little merb lib which I'm using for attachments. Very simple, S3 and more will be added as time goes on.

You could say what all the funny kids are saying these days:
It's Sofa King Simple!

Nice utility, I've been using ImageScience with pleasant results, but I'm really looking forward to trying this out. Not only will my code base shrink I can eliminate the _one_ compiled from source application on my servers.

f****** could mean anything! I for one read it as "fancy".

Anyway, this looks awesome. Someone should add it as a processor for attachment_fu...

Steve:
Yes, because when you do 'apt-get install imagemagick librmagick-ruby' it still doesn't work. Not on my system, anyway.

ImageMagick is a pain to install?

apt-get install imagemagick librmagick-ruby

C'mon, isn't Super Simple good enough? Can't you express yourself without "f*****" and "goddam"? Grow up!

For the user and company avatars in RailsCollab, i just installed the GD2 bindings for ruby and ended up with this relatively simple code.

max_width = AppConfig.max_logo_width
max_height = AppConfig.max_logo_height

begin
data = value.read
image = GD2::Image.load(data)
image.resize!(image.width > max_width ? max_width : image.width,
image.height > max_height ? max_height : image.height)
rescue
self.errors.add(:avatar, "Invalid data")
return
end

Granted, could be simpler. But it works. ;)
