GraphicsPath.Reset Method ()

 

Empties the PathPoints and PathTypes arrays and sets the FillMode to Alternate.

Namespace:   System.Drawing.Drawing2D
Assembly:  System.Drawing (in System.Drawing.dll)

public void Reset()

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

  • Creates a path.

  • Adds several primitives to it.

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

  • Resets the path to an empty state.

  • Re-acquires the points array (if it exists).

  • Draws the array to the screen.

Notice that it finds no array following the reset call.

public void GraphicsPathResetExample(PaintEventArgs e)
{
    Font myFont = new Font("Arial", 8);

    // Create a path and add a line, an ellipse, and an 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 pre-reset points array to the screen.
    DrawPoints1(e, myPath.PathPoints, 20);

    // Reset the path.
    myPath.Reset();

    // See if any points remain.
    if(myPath.PointCount > 0)
    {

        // Draw the post-reset points array to the screen.
        DrawPoints1(e, myPath.PathPoints, 150);
    }
    else

        // If there are no points, say so.
        e.Graphics.DrawString("No Points",
            myFont,
            Brushes.Black,
            150,
            20);
} 
//End GraphicsPathResetExample

// A helper function GraphicsPathResetExample uses to draw the points.

// to the screen.
public void DrawPoints1(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
