Hi folks!
I just wanted to tell you that Sparrow has its own atlas generator now. It's already available via SVN, so if you're tired of the other tools or manually creating your atlas, give it a try =)
It is in the "sparrow/sparrow/util/atlas_generator" folder.
It's a Ruby* script that takes an arbitrary number of images (say, my_textures\*.png), and creates an atlas from these images.
You need to have the image processing tool "ImageMagick" installed, though. Have a look at the README file, it will get you started.
Any feedback and bug reports are welcome!!!
Daniel
