Processing a Bitmap in Scene Graph

I'm new to the platform and I'm trying to figure out if there is a way to manipulate data for an image loaded via http in Scene Graph (i.e., perform image processing).

I started by attempting to use roTextureManager to get a bitmap, but that component apparently can only run on the main thread, so in the render thread I tried changing a global (which is observed by the main thread) in order to kickoff loading the bitmap using roTextureManager in the main thread. I can get the bitmap loaded that way, but can't figure out how to get it back to the render thread (using an observed global doesn't seem to work for a bitmap). Even if I can get it back to the render thread, it looks like it may not be possible to create and render the processed image there.

Is there a way to perform image processing in Scene Graph (using an image filtering algorithm), or does Scene Graph only support basic image display? Thanks.
