发明名称 METHOD AND APPARATUS FOR LOW MEMORY RENDERING
摘要 <p>A method and an apparatus used, for example, in conjunction with a computer or similar device, provides for multi-resolution rendering of image data, where the image data includes background image data, vector data and text data, so as to accommodate memory capacities of rendering devices. The computer may send image data in a multi-resolution format from the computer to one of several rendering devices. The multi-resolution format may be achieved by frequency domain coding or generation of image swaths, or a combination thereof. The image data may first be sent in a low resolution format, and a rendering device determines, based on its memory, whether the corresponding image or text should be rendered. Next, vector data and/or text data may be supplied to the rendering device. Then, higher resolution data may be sent after the text/vector date so as to maximize memory usage of the rendering device. Additionally, in a printing application, the image data may be divided into swaths, with each swath separately provided to a printer.</p>
