You have two possibilities to do that : 1) Use [pix_snap] to capture a part of the frame buffer and then apply [pix_scanline]. This method is the simplest but could be slow for your hardware. 2) Use [gemframebuffer] to render off-screen and convert this framebuffer into texture. Then use shaders (GLSL) to perform a [pix_scanline] like. Try this method if the first is too slow. ++ Jack
