Asynchronous (i.e. fast) readback from a framebuffer in OpenGL into a Jitter matrix.
|matrixoutput||int||Output a copy of the frame buffer (OpenGL render context). The output matrix dimensions adapt to the size of the window.|
|mode||symbol|| Sets the reading mode. The available modes are:
split: Split reads a single frame in two passes and the output is concurrent.
interleaved: Interleaved reads an entire frame into each internal buffer, switching buffers every other frame. In interleaved mode, the readback is delayed for one frame.
|out_name||symbol||(get)||Returns the name of the internal frame buffer (OpenGL render context).|
