Ruby/Rails - Forum signature images

I would like my Rails app to somehow generate forum signature images, like this one:

I couldn't really find anything on Google. Have anyone开发者_开发知识库 seen any kind of implementation of this in Ruby (I'm guessing with ImageMagick) ?

If not, how can I go about doing this?

Have you tried rMagick? Is an interface between ruby and ImageMagick... The URL is: http://rmagick.rubyforge.org/

For doing that sort of image creation, RMagick (the Ruby interface to ImageMagick) is probably going to be your best bet.

That said, think carefully about how you're going to implement this. You're probably NOT going to render these types of complex images on-the-fly, during the course of a web request, or your application is going to become very sluggish. Consider using a scheduled job that will render these images a few times a day at most.
