Android Canvas Clip parameter explanation

When Android operates a canvas, several areas can be manipulated (including with, or, not, XOR, and so on), and the sample code is as follows

            Canvas.save ();            Canvas.translate (ten, 310);            Canvas.cliprect (0, 0,.);            Canvas.cliprect (Max, Max, N, Region.Op.XOR);   The second rect is the XOR of the first rect.            drawscene (canvas);            Canvas.restore ();

The last parameter has several choices, namely:

1 Normal No clip

2 difference based on the area of the first time, the part that differs from the second time is shown

3 REPLACE shows the second time

4 UNION Show All

5 XOR complement set (complete minus intersection) section shows

6 reverse_difference based on the second area, show the parts that are different from the first

7 INTERSECT Intersection display
