lcPaint_PtbufAddArcSDE

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

BOOL lcPaint_PtbufAddArcSDE (
   HANDLE hPtbuf,
   double Xs,
   double Ys,
   double DirAngle,
   double Xe,
   double Ye,
   int Resol
);

Parameters

hPtbuf
	Handle to points buffer.
Xs Ys
	Arc start point coordinates.
DirAngle
	Arc direction angle from the start point.
Xe Ye
	Arc end point coordinates.
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.
