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
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.
