    • A method of creating transparent graphics for display in a computer system. A first frame buffer is provided to store display components to be displayed transparently on a computer monitor, the display components having a plurality of pixels. A second frame buffer is provided as a new output frame buffer. Pixels of the first frame buffer are color mixed with pixels of the computer system's original output frame buffer to produce color mixed pixels. The pixels of the output frame buffer are interleaved with the color mixed pixels, the interleaved pixels are stored in the second frame buffer, and the pixels of the second frame buffer are displayed. The color mixing is accomplished by a weighted average of the color components of the pixels of the first frame buffer and the output frame buffer. The interleaving is adjustable such that every second pixel, or every fourth pixel, or every eighth pixel, and so on, of the color mixed pixels is selected for inclusion in the second frame buffer, thereby changing the level of transparency of the displayed data.
    • 一种创建透明图形以在计算机系统中显示的方法。 提供第一帧缓冲器以存储要在计算机监视器上透明地显示的显示组件,所述显示组件具有多个像素。 提供第二帧缓冲器作为新的输出帧缓冲器。 第一帧缓冲器的像素与计算机系统的原始输出帧缓冲器的像素混合以产生颜色混合像素。 输出帧缓冲器的像素与彩色混合像素交错,交错像素被存储在第二帧缓冲器中,并且显示第二帧缓冲器的像素。 混色通过第一帧缓冲器和输出帧缓冲器的像素的颜色分量的加权平均来完成。 交织是可调的,使得选择颜色混合像素的每个第二像素或每第四个像素,或每八分之一像素等,以包括在第二帧缓冲器中,从而改变显示数据的透明度。
