6、图像翻转(上下对折)代码:Graphics g = cs; Bitmap bmp = new Bitmap(""); Point[] points = {new Point (0,100),new Point (100,100),new Point (0,0) }; age(bmp, points);输出:7、旋转 Graphics g = cs; Bitmap bmp = new Bitmap(""); Point[] points = {new Point (100,0),new Point (100,100),new Point (0,0) }; age(bmp, points);输出:说明:顺时针旋转90度8、复制图像代码:Graphics g = cs; Bitmap bmp = new Bitmap(""); Bitmap bmp2 = (new Rectangle(50, 50, - 50, - 50), re);

age(bmp,0,0); age(bmp2,200,0);

输出:9、在内存中创建位图代码:Graphics g = cs; Bitmap bmp = new Bitmap(100,100); Graphics gImg = age(bmp ); ctangle(Brushes .Red ,new RectangleF (0,0,50,50)); ctangle(Pens .Black , new Rectangle(0, 0, 50, 50)); age(bmp,0,0);

输出:10、双倍缓存 le(zedDoubleBuffer, true); le(ntingInWmPaint ,true); le(int ,true );11、处理图像中得alpha成分
