我正在使用 Pixel 在大图像和小图像之间进行搜索。我让那个成功工作，但在让 lockbits 版本做我想做的事情时遇到了麻烦。
拳头我想遍历大图像，在其中找到较小图像的第一个像素。然后一旦找到第一个像素来做一个数学方程，告诉我它得到了多少准确率。这样做时，如果它符合将我的鼠标移动到屏幕上大图像内那个小图像的第一个像素（最左上角）的那个位置的标准。与 GetPixel 格式相比，它的成功率很高，而且速度极快。
问题无法在大图像上获取小图像的起始像素所在的位置并将鼠标移动到该位置。下面是代码：

现在，如果我能弄清楚如何让鼠标在屏幕上移动，那么我就会明白了。不幸的是，我已经为此工作了几天，但没有任何成功。如果您能提供帮助，我将不胜感激。先感谢您。
