HARDWARE ACCELERATED CARET RENDERING |
摘要 |
Techniques for hardware accelerated caret rendering are described in which a system based caret is emulated using hardware acceleration technology. The hardware accelerated caret can be rendered using dedicated graphics processing hardware to look and feel like a system caret. This can involve using pixel shaders to produce the hardware accelerated caret and a employing a back-up texture to remove the caret after it is drawn and cause the caret to blink. In addition, rendering of the caret can be coordinated with other animations and/or other presentations of a frame buffer to piggy back drawing of the caret onto other drawing operations. This can reduce the number of times the frame buffer is presented and therefore improve performance.
