搜索屏幕上像素的最有效方法？
Windows api 中的 GetPixel 似乎工作正常，但对于分辨率高达 1920x1080 的屏幕来说，它需要花费大量时间（几分钟）。我怀疑是 GetPixel 函数（可能需要几厘秒的处理时间）导致整个过程滞后。我想知道直接访问内存映射是否可以解决这个问题？或者有更好的近似方法吗？我希望实现的是搜索时间少于 5 秒。
GetPixel in windows api seems to work fine, but it just takes ridiculously large amount of time (several minutes) for a screen of resolution as large as 1920x1080. I am suspecting that it is the GetPixel function, which probably takes several centiseconds to process, is lagging the whole thing behind. I was wondering if directly accessing the memory map could solve this problem? Or is there a better approximation method? What i'm hoping to achieve is searching less than 5 seconds.

您可以截取当前屏幕的屏幕截图，然后使用收到的位图进行搜索。这样，您将可以访问自己的内存，并且比调用
GetPixel()2073600 次要快得多。You could take a screen shot of the current screen, and search with the bitmap you receive. That way, you'll be accessing your own memory, and it'll be much faster than calling
GetPixel()2073600 times.
