lcPaint_PtbufAddArcSEB

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

BOOL lcPaint_PtbufAddArcSEB (
   HANDLE hPtbuf,
   double Xs,
   double Ys,
   double Xe,
   double Ye,
   double Bulge,
   int Resol
);

Parameters

hPtbuf
	Handle to points buffer.
Xs Ys
	Arc start point coordinates.
Xe Ye
	Arc end point coordinates.
Bulge
	Bulge coefficient (<arc deviation> / <half-length of start-end line>). Negative coefficient means clockwise arc direction (deviation to the left side of start-end line), positive - counter-clockwise arc 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.
