You have two possibilities to do that :
- 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.
btw, you might want to use [gemframebuffer] for method #1 as well, so the to-be-processed scene does not get in the way of the finally displayed scene.
