GraphicsPath.Reverse Method

Definition

Namespace:

System.Drawing.Drawing2D

Assembly:

System.Drawing.Common.dll

Source:

GraphicsPath.cs

Reverses the order of points in the PathPoints array of this GraphicsPath.

C#

public void Reverse();

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

• Creates a path and adds several primitives to the path.

• Draws the path's points array to the screen.

• Draws the reversed points array to the screen.

Notice that the second listing of points is in reverse order from the first.

C#

public void GraphicsPathReverseExample(PaintEventArgs e)
{
             
    // Create a path and add a line, ellipse, and arc.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddLine(new Point(0, 0), new Point(100, 100));
    myPath.AddEllipse(100, 100, 200, 250);
    myPath.AddArc(300, 250, 100, 100, 0, 90);
             
    // Draw the first set of points to the screen.
    DrawPoints2(e, myPath.PathPoints, 20);
             
    // Call GraphicsPath.Reverse.
    myPath.Reverse();
             
    // Draw the reversed set of points to the screen.
    DrawPoints2(e, myPath.PathPoints, 150);
}
//End GraphicsPathReverseExample.
             
// A helper function GraphicsPathReverseExample is used to draw the
             
// points to the screen.
public void DrawPoints2(PaintEventArgs e, PointF[] pathPoints, int xOffset)
{
    int y = 20;
    Font myFont = new Font("Arial", 8);
    for(int i=0;i < pathPoints.Length; i++)
    {
        e.Graphics.DrawString(pathPoints[i].X.ToString() + ", " +
            pathPoints[i].Y.ToString(),
            myFont,
            Brushes.Black,
            xOffset,
            y);
        y += 20;
    }
} 
// End DrawPoints
