I have been wondering about possibility to use Gnash as a general-purpose
animation renderer for a long time. But as SWF has an opaque color-filled
background, the rendered animation frames couldn't be easily overlaid on
other pieces of film or video. To accomodate these uses, Gnash would need
to support rendering/screenshotting/video-dumping SWF without filling
background color.
In order to make this work, Gnash (at least with AGG-based renderer)
would have to do following things:
* Gnash would need to support 32-bit RGB+alpha PNG screenshot output.
* Gnash would need to support 32-bit RGB+alpha video output.
* Renderer would need to render with alpha channel support, on
alpha-supporting canvas.
* Gnash would need to be able to turn off rendering of SWF background color
(or render it as transparent) on request.
* Gnash would need to provide a command line switch to turn off SWF
background.
