Constructs a point array with room for size points. For internal use only. Positive values mean counter-clockwise while negative values mean clockwise direction. Zero degrees is at the 3'o clock position. The resulting array has sufficient resolution for pixel accuracy.
Positive values mean counter-clockwise while negative values mean clockwise direction.
Zero degrees is at the 3'o clock position. Assigns a shallow copy of a to this point array and returns a reference to this point array. Copies nPoints points from the points array into this point array. Copies nPoints points from the variable argument list into this point array. Resizes the array to nPoints and sets the points in the array to the values taken from points.
