How to: Draw a Line Filled with a Texture

Instead of drawing a line with a solid color, you can draw a line with a texture. To draw lines and curves with a texture, create a xref:System.Drawing.TextureBrush object, and pass that xref:System.Drawing.TextureBrush object to a xref:System.Drawing.Pen.%23ctor%2A constructor. The bitmap associated with the texture brush is used to tile the plane (invisibly), and when the pen draws a line or curve, the stroke of the pen uncovers certain pixels of the tiled texture.

Example

The following example creates a xref:System.Drawing.Bitmap object from the file Texture1.jpg. That bitmap is used to construct a xref:System.Drawing.TextureBrush object, and the xref:System.Drawing.TextureBrush object is used to construct a xref:System.Drawing.Pen object. The call to xref:System.Drawing.Graphics.DrawImage%2A draws the bitmap with its upper-left corner at (0, 0). The call to xref:System.Drawing.Graphics.DrawEllipse%2A uses the xref:System.Drawing.Pen object to draw a textured ellipse.

The following illustration shows the bitmap and the textured ellipse:

Compiling the Code

Create a Windows Form and handle the form's xref:System.Windows.Forms.Control.Paint event. Paste the preceding code into the xref:System.Windows.Forms.Control.Paint event handler. Replace Texture.jpg with an image valid on your system.
