Texture Atlas (Sprite Sheet) Generator

UPDATE: A few people have asked, so we’ve released the source code for the tool in the download links below. We’re unable to make any modifications to it, as we’re no longer developing the tool internally, but feel free to modify it for your own needs, and contact us if you need any help with it. Unfortunately, the code isn’t the tidiest code around. Please note that all source and binary code is provided “as is”, without any warranty of any kind. Please see the website usage terms, at the bottom of the page, for more information.
