c# 怎么能把图片 按照不规则的形状切割   可以利用遮盖的 形式实现??
如题!
------解决方案--------------------Dim CurImage As Image = New Bitmap(DrawRectangle.Width, DrawRectangle.Height) 
                 Dim g As Graphics = Graphics.FromImage(CurImage) 
                 Dim FromRectangle As Rectangle 
                 Dim ToRectangle As Rectangle 
                  '=========================================== 
                 FromRectangle = New Rectangle(DrawRectangle.X, DrawRectangle.Y, DrawRectangle.Width, DrawRectangle.Height) 
                 ToRectangle = New Rectangle(0, 0, DrawRectangle.Width, DrawRectangle.Height) 
                 g.Clear(Color.White) 
                 g.DrawImage(PicBox.Image, ToRectangle, FromRectangle, GraphicsUnit.Pixel) 
                 My.Computer.Clipboard.SetImage(CurImage)   
 这个例子是把一个图形的某一个区域截取出来 
 你的情况和它的区别只在于,你的区域是不规则形状罢了,在图形绘制上,规则和不规则,没有区别。
