| 项目描述: |
The code works by creating a memory compatible DC and Bitmap to that of the picture within the PictureBox. The PictureBox is then cleared and has it's background set to various shades of gray (eventually black) - the bitmap is then 'blitted' to the PictureBox and each pixel is 'AND'ed with the background colour to achieve the fade effect.
这段代码可以创建一个内存兼容的DC和一个位图，这个位图可以位于一个图片框中。接着清除图片框的内容，将它的背景设置成各种灰度级的灰色（最终为黑色），再将这一位图复制到图片框，每个像素和背景色进行“与”运算，取得色彩渐变的效果。
