lcPaint_PtbufAddArcCSA

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

BOOL lcPaint_PtbufAddArcCSA (
   HANDLE hPtbuf,
   double Xc,
   double Yc,
   double Xs,
   double Ys,
   double ArcAngle,
   int Resol
);

Parameters

hPtbuf
	Handle to points buffer.
Xc Yc
	Arc center point coordinates.
Xs Ys
	Arc start point coordinates.
ArcAngle
	Included angle of the arc. Negative value means clockwise arc's direction from the start angle, Positive value means counter-clockwise direction.
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.
