An input image containing high resolution images and low resolution images is rasterized twice, once at a high resolution and once at a low resolution. The rasterized images are represented in compressed form using a run-code encoding technique. The low resolution images are rasterized during the low resolution rasterization and are scaled to the output resolution. The high resolution images are rasterized during the high resolution rasterization. The two rasterizations are merged in hardware, producing a composite output image which contains low resolution image elements and high resolution image elements. |
