摘要： Foreground images, such as cursors, may be displayed over an image by selecting individual pixel colors to contrast with surrounding background pixels. The background pixels in, around and behind the foreground image may be converted from a red-green-blue (RGB) color space to a luminance isolating color space, such as YUV, HSL or the like. The converted pixel information may be copied, stored, or drawn into a separate compositing window. After converting to the luminance isolating color space, the luminance values of the pixels may be adjusted to increase the contrast between the foreground image and the background image. Portions of the foreground image may also be blurred, such as by applying a Gaussian or box blur, such as to soften the edges. The pixel information may then be converted back into the RGB color space and blended with the background information using alpha information for the foreground and background images.
摘要翻译：通过选择单独的像素颜色来与周围的背景像素进行对比，可以在图像上显示诸如光标的前景图像。可以将前景图像中，前后图像周围和后面的背景像素从红 - 绿 - 蓝（RGB）颜色空间转换为亮度隔离颜色空间，例如YUV，HSL等。转换的像素信息可以被复制，存储或绘制到单独的合成窗口中。在转换为亮度隔离色彩空间之后，可以调整像素的亮度值以增加前景图像和背景图像之间的对比度。前景图像的部分也可能被模糊，例如通过应用高斯或框模糊，例如软化边缘。然后可以将像素信息转换回RGB色彩空间并使用前景和背景图像的alpha信息与背景信息混合。
