How to: Draw a Line with Line Caps

You can draw the start or end of a line in one of several shapes called line caps. GDI+ supports several line caps, such as round, square, diamond, and arrowhead.

Example

You can specify line caps for the start of a line (start cap), the end of a line (end cap), or the dashes of a dashed line (dash cap).

The following example draws a line with an arrowhead at one end and a round cap at the other end. The illustration shows the resulting line:

Compiling the Code

• Create a Windows Form and handle the form's xref:System.Windows.Forms.Control.Paint event. Paste the example code into the xref:System.Windows.Forms.Control.Paint event handler passing e as xref:System.Windows.Forms.PaintEventArgs.
