u 是否知道任何能够加速2种原始产品的技术,如线和圈子?
i 开发应用系统,使含有此类原始材料的ed刻图像成为可能。 可以通过窗口式 desktop(包括小组通过直径选择)的相同方式迁移和甄选。 此外,还着重提到 cur子。
看来,在使用 mo时,许多显示都得到了更新。 因此,需要明智地这样做。
i 知道:
- changing GDI+ to D3D can speed up display greately
- dirty rects allow to restrict updates to only those rectangles that changed. (major drawback is that rectangles containing lines can be as big as display area)
- xor technique allow to clear primitive by drawing it second time. (drawback is that it seems to be useless with multicolor images and primitives with common points)
