You may wish to use a "Mapgraphic" or decorator to display feedback on the map that moves around with the map. The draw shape command is mostly intended for visual feedback when using a tool. You can (if needed) update the data that your draw shape command uses (your teste Line2D in this case) so that the line is scaled as the map zoom changes. It is best to record your positions as "coordinates" in this case; and use the viewport methods to transform them into pixels as needed.
