glBlitFramebuffer

copy a block of pixels from one framebuffer object to another

function glBlitFramebuffer(int $srcX0, int $srcY0, int $srcX1, int $srcY1, int $dstX0, int $dstY0, int $dstX1, int $dstY1, int $mask, int $filter) : void

arguments

1. int $srcX0 Specify the bounds of the source rectangle within the read buffer of the read framebuffer.
2. int $srcY0
3. int $srcX1
4. int $srcY1
5. int $dstX0 Specify the bounds of the destination rectangle within the write buffer of the write framebuffer.
6. int $dstY0
7. int $dstX1
8. int $dstY1
9. int $mask The bitwise OR of the flags indicating which buffers are to be copied. The allowed flags are GL_COLOR_BUFFER_BIT, GL_DEPTH_BUFFER_BIT and GL_STENCIL_BUFFER_BIT.
