SWF Tools Filter

The basic syntax for embedding a flash file (.swf), flash movie (.flv) or audio file (.mp3) is:

<swf file="filename.swf">

If you would like to override SWF Tools and flash player default settings, you can specify additional parameters. For example:

<swf file="song.mp3" flashvars="backcolor=#AABBCC&&forecolor=#11AA11">

If you would like to output a list of files then the format is:

<swf files="image1.jpg&&image2.jpg&&...">
SWF Tools Filter will accept following:

WARNING: with params, flashvars and othervars, pass multiple values separated by &&.
