查找图像的颜色非常简单.一旦找到图像的颜色，然后进行比较.比较后即可找到您的类型.
试试这个:

Hi,
It''s quite simple to find the color of the image. Once found the color of the image then compare that. You''ll find your type after comparing.
Try this:

Point pt=new Point(10,10);
Bitmap img = Image.FromFile("My File Path");
Color colorAtPoint = img.GetPixel(pt);
//Here you got the color of your image. Compare it with Grayscale

请参考此 [

尝试一下，
它将对您有帮助.

Try this,
It will help you.

Dim btmp as Bitmap = Image.FromFile("Your File Path")
Dim clr as Color = btmp.GetPixel(New Point(100,0))

在这里，clr的颜色将为Point(100,0).您可以根据自己的意愿进行更改.
如果要在整个图像中进行比较，则可以使用for循环，只需更改点即可.

谢谢.

Here clr will have the color at the Point (100,0). You can change it as your wish.
If you want to compare it in the whole image then you can do it using for loop by just changing the point.

Thanks.
