- dx
- The amount to add to the x-coordinate of the end of the previous contour, to specify the start of a new contour
- dy
- The amount to add to the y-coordinate of the end of the previous contour, to specify the start of a new contour
Set the beginning of the next contour relative to the last point on the previous contour. If there is no previous contour, this is treated the same as moveTo().
