lcPaint_PtbufAddArc3p

Adds a set of points into a points buffer. The points represent an arc shape.

BOOL lcPaint_PtbufAddArc3p (
   HANDLE hPtbuf,
   double X1,
   double Y1,
   double X2,
   double Y2,
   double X3,
   double Y3,
   int Resol
);

Parameters

hPtbuf
	Handle to points buffer.
X1 Y1
	Arc start point coordinates.
X2 Y2
	Arc middle point coordinates.
X3 Y3
	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.
