boundingBox - The bounding box.

Returns:

The bounding box.

zoom

void zoom(ComponentViewport2D viewport,
        BoundingBox boundingBox)

Zoom the map so that the specified bounding box is visible.

Parameters:

viewport - The viewport.

boundingBox - The bounding box.

zoom

void zoom(ComponentViewport2D viewport,
        double x1,
        double y1,
        double x2,
        double y2)

Zoom the map to include the bounding box specified by the model coordinate pair.

Parameters:

viewport - The viewport.

x1 - The first x coordinate.
