freddymx/Dynamic-Texture-Atlas-Generator
This tool will convert any MovieClip containing Other MovieClips, Sprites or Graphics into a starling Texture Atlas, all in runtime. By using it, you won't have to statically create your spritesheets. Just take a regular MovieClip containing all the display objects you wish to put into your Atlas, and convert everything from vectors to bitmap textures. This extension could save you a lot of time specially if you'll be coding mobile apps with the starling framework. For more info, please refer to the README.md File
