Re: [Groff] Problems with arcs and angles

Sorry, I just noticed that your drawing canvas measures the angles clockwise rather than the traditional counterclockwise so you need to negate the y coordinates to atan2: startAngle = Math.atan2(centreY - startY, startX - centreX) endAngle = Math.atan2(centreY - endY, endX - centreX) -Larry >
