Method Detail

### glBlitFramebufferEXT

    public static void glBlitFramebufferEXT(int srcX0,
                                            int srcY0,
                                            int srcX1,
                                            int srcY1,
                                            int dstX0,
                                            int dstY0,
                                            int dstX1,
                                            int dstY1,
                                            int mask,
                                            int filter)

  Transfers a rectangle of pixel values from one region of the read framebuffer to another in the draw framebuffer. <mask> is the bitwise OR of a number of values indicating which buffers are to be copied. The values are COLOR_BUFFER_BIT, DEPTH_BUFFER_BIT, and STENCIL_BUFFER_BIT. The pixels corresponding to these buffers are copied from the source rectangle, bound by the locations (srcX0, srcY0) and (srcX1, srcY1) inclusive, to the destination rectangle, bound by the locations (dstX0, dstY0) and (dstX1, dstY1) inclusive. If the source and destination rectangle dimensions do not match, the source image is stretched to fit the destination rectangle. <filter> must be LINEAR or NEAREST and specifies the method of interpolation to be applied if the image is stretched.
