The setRotation() method sets the rotation for the map projection.
public void setRotation(int rot)
public void setRotation(float rot)
public void setRotation(double rot)
public void setRotation(String rot)
The angle through which the North direction should be rotated around the line L between the Earth's center and the point (lat, lon). This angle is measured in degrees with the positive direction being clockwise around the line L, and must be in the range -180° £ rot £ 180°. The default is 0.
If the center of the map is at the North pole, North is in the direction lon + 180°. If the origin is at the South pole, North is in the direction lon.
None.
