Abstract: PROBLEM TO BE SOLVED: To provide a computer-implemented display system, in particularly, a system and method of rendering translucent and complex-shaped overlapping layers in a short process time. SOLUTION: For overlapping layers in a computer display, such as a window system, front-to-back assembly of the displayed image is used so that an arbitrary number of overlapping elements, such as windows can be presented, without requiring temporary storage space or additional off-screen buffers. The front-to-back assembly technique minimizes the number of memory transfers performed in connection with rendering of an image, and avoids unnecessary reading and processing of pixels that does not contribute to the final image. Special effects, such as semi-transparency, shadows and irregular shapes, can be accommodated and processed. COPYRIGHT: (C)2008,JPO&INPIT

解决方案：对于诸如窗口系统的计算机显示器中的重叠层，使用显示图像的前后组装，使得可以呈现任意数量的重叠元件，例如窗口，而不需要临时 存储空间或附加的屏幕外缓冲区。 前后组装技术最大限度地减少了与渲染图像相关的内存传输次数，避免了对最终图像无贡献的像素的不必要的读取和处理。 可以适应和处理特殊效果，如半透明度，阴影和不规则形状。 版权所有（C）2008，JPO＆INPIT

Abstract: Digital graphic design and image editing applications (hereafter collectively referred to as image editing applications) provide graphical designers, media artists, and other users with the necessary tools to view and edit an image. Examples of such applications are Picasa, which is provided by Google, Photoshop, which is provided by Adobe, Express Media, which is provided by Microsoft, etc. These applications give users the ability to edit images in a variety of manners. With the proliferation of mobile devices such as tablet computers and smartphones, the utility of these applications has expanded to these devices. However, many image editing applications are adapted for stationary devices like desktops and servers and do not provide with the users with some of the convenient features that could be enjoyed at the mobile devices.
