The following example creates a
CustomLineCap and sets the base inset of the cap. It then assigns the custom cap to a
Pen and draws a line.
C++
VOID Example_SetBaseInset(HDC hdc)
{
Graphics graphics(hdc);
//Create a Path object.
GraphicsPath capPath;
//Create a CustomLineCap object and set its base cap to LineCapRound.
CustomLineCap custCap(NULL, &capPath, LineCapRound, 5);
// Create a Pen object, assign custCap as the custom end cap, and then
// draw a line.
Pen pen(Color(255, 0, 0, 0), 5.1f);
pen.SetCustomEndCap(&custCap);
graphics.DrawLine(&pen, Point(0, 0), Point(100, 100));
}
