lcPaint_PtbufAddArcSEL

Adds a set of points into a points buffer. The points represent an arc shape, defined by Start, End, arc Length.

BOOL lcPaint_PtbufAddArcSEL (
   HANDLE hPtbuf,
   double Xs,
   double Ys,
   double Xe,
   double Ye,
   double ArcLen,
   BOOL bClockwise,
   int Resol
);

Parameters

hPtbuf
	Handle to points buffer.
Xs Ys
	Arc start point coordinates.
Xe Ye
	Arc end point coordinates.
ArcLen
	Arc length.
bClockwise
	Defines arc direction from start to end point: TRUE - clockwise, FALSE - counter-clockwise.
Resol
	Arc resolution. The value means a number of points per 360 degrees. Can be only the following vales: 16, 32, 64, 128, 256, 512. If the arc included angle is so low that result number of points is less then 5, then the function adds an extra points.

Return Value

If the function succeeds, the return value is nonzero (TRUE).

Remarks

To know the number of points was added by this function, read the global property LC_PROP_G_PTBUFNEWPTS just after the function execution.
