Getting the pixel data of a sprite after scale, filter etc

I know how to get the raw pixel data of the original texture of an image sprite, but is there a way to get the pixel data of the sprite just before it is composited with all of the other elements, but after it has been altered by scaling, filters, etc?

renderer.extract.pixels(mysprite) seems to just return the original texture no matter what transformations have been performed on the sprite.
