as3swf is a low-level ActionScript 3 library for parsing, creating, modifying, and emitting SWF files. It gives programmatic access to SWF structure (tags, binary content, shapes, actions, etc.), and allows developers to read SWF files, manipulate them in code (e.g. change shapes, embed assets, alter frame data), and write them back out. as3swf is released under the MIT license. Parse, create, modify and publish SWF files. Modify SWF content: insert, remove, or alter tags or objects within the SWF.
