arcTo - method of the CanvasCtx object

Creates an arc between two tangents.
Object arcTo(Long x1, Long y1, Long x2, Long y2, Long r)
x1(Long) The x-coordinate of the beginning of the arc
y1(Long) The y-coordinate of the beginning of the arc
x2(Long) The x-coordinate of the end of the arc
y2(Long) The y-coordinate of the end of the arc
r(Long) The radius of the arc
The method creates a path. Therefore before calling this method the beginPath method should be called. For the rendering itself the stroke or fill method is used.

This method is also functional in Web panels.
