Description

Draws a series of lines on drawable between the specified sequence of points, using the current pen. Dashed lines start dashing from the first point of each line.

The function draw-lines* is identical to draw-line, except that it passes composite objects, rather than separate coordinates, in its arguments. You should be aware that using this function may lead to a loss of performance.

Example

           vector(100, 150, 
                  200, 250, 
                  300, 350, 
                  400, 450));
