Graphics.IntersectClip Method (Region)
Assembly: System.Drawing (in system.drawing.dll)
This method assigns to the Clip property of this Graphics the area represented by the intersection of the current clip region and the region specified by the region parameter.
The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:
-
Creates a rectangle with upper-left corner at (0, 0).
-
Creates a region and sets it to the rectangle, and sets the clipping region to this region.
-
Creates a second rectangle with upper-left corner at (100, 100).
-
Creates a region and sets it to the second rectangle, and sets the clipping region to the intersection of this region and the current clipping region (the first rectangle) using a combine mode of Replace.
-
Fills a large rectangle that includes both previous regions with a solid blue brush.
-
Resets the clipping region to infinite.
-
Draws rectangles around the two clipping regions. It uses a black pen for the first clipping region and a red pen for the second clipping region.
The result is that only the intersection of the two regions is filled with blue.
