How to get the RGB values of each pixel in the windows form with GDI+ ?
Hi all, I'm new to GDI+ and C#,
Recently, I try to implement a painer,
I want to get each pixel's RGB values in the form when I click the mouse.
In the MouseDown function,
I have tried "this.GetChildAtPoint(pt).ForeColor.ToArgb();",
but "Exception Error!!" comes up.
How should I solve this problem?
Thanks... :)
