FreeMovie is a library for generating and parsing Macromedia Flash(tm) SWF files. It is an alternative to the official Macromedia Flash(tm) (SWF) file format SDK. The author’s aim is to build a high-level API for generating SWF files in PHP and other languages, such as Perl, Python, Ruby, Tcl, or VB.Net.

The main features of FreeMovie are TrueType-to-SWF font conversion (unstable), support for multiple bitmap image formats (JPEG-stable, TIFF-unstable, more to come), and a high-level drawing, sound and animation API (in works).
