static

Fast implementation of the arc points calculation.

Inputs: centerX, centerY: arc center in pixel radius: arc radius in pixel startAngle, endAngle: start and end angle of the arc in grad

Outputs: xPoints, yPoints: vectors of the calculated points coordinates

Returns: true if arc points have been calculated, otherwise false
