Examples

The following example demonstrates how to use the DrawToBitmap method to draw a LineShape on top of a PictureBox control.

Dim pic As New System.Drawing.Bitmap(Me.PictureBox1.Image,
 PictureBox1.Width, PictureBox1.Height)
Dim rect As New System.Drawing.Rectangle(LineShape1.X1,
    LineShape1.Y1, LineShape1.X2 - LineShape1.X1,
    LineShape1.Y2 - LineShape1.Y1)
LineShape1.DrawToBitmap(pic, rect)
PictureBox2.Image = pic
System.Drawing.Bitmap pic = new System.Drawing.Bitmap(this.pictureBox1.Image, 
    pictureBox1.Width, pictureBox1.Height);
System.Drawing.Rectangle rect = new System.Drawing.Rectangle(lineShape1.X1, 
    lineShape1.Y1, lineShape1.X2 - lineShape1.X1, lineShape1.Y2 - lineShape1.Y1);
lineShape1.DrawToBitmap(pic, rect);
pictureBox2.Image = pic;
