示例
下面的代码示例设计用于 Windows 窗体,它需要 PaintEventArgse
,这是 Paint 事件处理程序的参数。 该代码执行以下操作:
创建第一个矩形并将其绘制到黑色屏幕。
创建第二个矩形并将其绘制到红色屏幕。
使用第一个矩形创建区域。
当与
complementRect
结合使用时,获取myRegion
的 Xor 区域。用蓝色填充 Xor 区域,并将其绘制到屏幕。
请注意,这两个矩形都填充了蓝色,但重叠区域除外。
void XorExample( PaintEventArgs^ e )
{
// Create the first rectangle and draw it to the screen in black.
Rectangle regionRect = Rectangle(20,20,100,100);
e->Graphics->DrawRectangle( Pens::Black, regionRect );
// create the second rectangle and draw it to the screen in red.
RectangleF xorRect = RectangleF(90,30,100,100);
e->Graphics->DrawRectangle( Pens::Red, Rectangle::Round( xorRect ) );
// Create a region using the first rectangle.
System::Drawing::Region^ myRegion = gcnew System::Drawing::Region( regionRect );
// Get the area of overlap for myRegion when combined with
// complementRect.
myRegion->Xor( xorRect );
// Fill the Xor area of myRegion with blue.
SolidBrush^ myBrush = gcnew SolidBrush( Color::Blue );
e->Graphics->FillRegion( myBrush, myRegion );
}
public void XorExample(PaintEventArgs e)
{
// Create the first rectangle and draw it to the screen in black.
Rectangle regionRect = new Rectangle(20, 20, 100, 100);
e.Graphics.DrawRectangle(Pens.Black, regionRect);
// create the second rectangle and draw it to the screen in red.
RectangleF xorRect = new RectangleF(90, 30, 100, 100);
e.Graphics.DrawRectangle(Pens.Red,
Rectangle.Round(xorRect));
// Create a region using the first rectangle.
Region myRegion = new Region(regionRect);
// Get the area of overlap for myRegion when combined with
// complementRect.
myRegion.Xor(xorRect);
// Fill the Xor area of myRegion with blue.
SolidBrush myBrush = new SolidBrush(Color.Blue);
e.Graphics.FillRegion(myBrush, myRegion);
}
Public Sub XorExample(ByVal e As PaintEventArgs)
' Create the first rectangle and draw it to the screen in black.
Dim regionRect As New Rectangle(20, 20, 100, 100)
e.Graphics.DrawRectangle(Pens.Black, regionRect)
' create the second rectangle and draw it to the screen in red.
Dim xorRect As New RectangleF(90, 30, 100, 100)
e.Graphics.DrawRectangle(Pens.Red, Rectangle.Round(xorRect))
' Create a region using the first rectangle.
Dim myRegion As New [Region](regionRect)
' Get the area of overlap for myRegion when combined with

myRegion.Xor(xorRect)
' Fill the intersection area of myRegion with blue.
Dim myBrush As New SolidBrush(Color.Blue)
