Transparent background

DX9Texture (EX9.Texture)
SetAlpha (Color)

The image rendered by a Renderer can be retrieved as a texture via the DX9Texture (EX9.Texture). This is useful if you need to write it to disk, post-process the image (aka TextureFX ) or use it in a feedback-loop.

In order to render on a transparent background the alpha in Background Color of the Renderer (DX9) must be <1 and the Format of the Renderer or the DX9Texture (EX9.Texture) must contain an alpha channel as well. Typically choose A8R8G8B8.
