                               PdfCanvas cv)
        Draw an arc on the passed canvas, enclosed by the rectangle for which two opposite corners are specified. The arc starts at the passed starting angle and extends to the starting angle + extent
        Parameters:
        x1 - corner-coordinate of the enclosing rectangle, first corner
        y1 - corner-coordinate of the enclosing rectangle, first corner
        x2 - corner-coordinate of the enclosing rectangle, second corner
        y2 - corner-coordinate of the enclosing rectangle, second corner
        startAng - starting angle in degrees
        extent - extent of the arc
        cv - canvas to paint on

                               AffineTransform transform)
        Draw an arc on the passed canvas with provided transform, enclosed by the rectangle for which two opposite corners are specified. The arc starts at the passed starting angle and extends to the starting angle + extent
        Parameters:
        x1 - corner-coordinate of the enclosing rectangle, first corner
        y1 - corner-coordinate of the enclosing rectangle, first corner
        x2 - corner-coordinate of the enclosing rectangle, second corner
        y2 - corner-coordinate of the enclosing rectangle, second corner
        startAng - starting angle in degrees
        extent - extent of the arc
        cv - canvas to paint on
        transform - AffineTransform to apply before drawing, or null in case transform shouldn't be applied
