Combined Lines and Curves
In addition to drawing lines or curves, applications can draw combinations of line and curve output by calling a single function. For example, an application can draw the outline of a pie chart by calling the AngleArc function.
The AngleArc function draws an arc along a circle's perimeter and draws a line connecting the starting point of the arc to the circle's center. In addition to using the AngleArc function, an application can also combine line and irregular curve output by using the PolyDraw function.
