Status:Open Resolved:
Product:Documentation Product Version:
Classification: Reproducible:Always
 
Summary:
The description of the location for the first tangent point for the function CGContextAddArcToPoint is incorrect. The position of the first tangent point as passed into the CGContextAddArcToPoint function is actually where the two tangent line intersect, not where the tangent line touches the circle. The position of the second tangent point is correctly described.
