Parameters
Examples
The following example demonstrates how to use the SetStrokeCaps method. To run this example, paste the code into a Windows Form. Handle the form's Paint event and call DrawCaps
from the form's Paint event-handling method, passing e
as PaintEventArgs.
protected void DrawCaps(PaintEventArgs e)
{
GraphicsPath hPath = new GraphicsPath();
// Create the outline for our custom end cap.
hPath.AddLine(new Point(0, 0), new Point(0, 5));
hPath.AddLine(new Point(0, 5), new Point(5, 1));
hPath.AddLine(new Point(5, 1), new Point(3, 1));
// Construct the hook-shaped end cap.
CustomLineCap HookCap = new CustomLineCap(null, hPath);
// Set the start cap and end cap of the HookCap to be rounded.
HookCap.SetStrokeCaps(LineCap.Round, LineCap.Round);
// Create a pen and set end custom start and end
// caps to the hook cap.
Pen customCapPen = new Pen(Color.Black, 5);
customCapPen.CustomStartCap = HookCap;
customCapPen.CustomEndCap = HookCap;
// Create a second pen using the start and end caps from
// the hook cap.
Pen capPen = new Pen(Color.Red, 10);
LineCap startCap;
LineCap endCap;
HookCap.GetStrokeCaps(out startCap, out endCap);
capPen.StartCap = startCap;
capPen.EndCap = endCap;
// Create a line to draw.
Point[] points = { new Point(100, 100), new Point(200, 50),
new Point(250, 300) };
// Draw the lines.
e.Graphics.DrawLines(capPen, points);
e.Graphics.DrawLines(customCapPen, points);
}
