SurfaceText has no rotation support #37
Description
Sometimes it is required to put SurfaceText rotated according North.
This possibility is absent but easy to add.
- Add angle attribute, its setter and getter to SurfaceText class.
- Add glRotated method call into applyDrawTransform.
See example of overridden class:
public class CustomSurfaceText extends SurfaceText {
private double angle;
public CustomSurfaceText(String text, Position position) {
super(text, position);
}
public CustomSurfaceText(String text, Position position, Font font, Color color) {
super(text, position, font, color);
}
public double getAngle() {
return angle;
}
public void setAngle(double angle) {
this.angle = angle;
}
@Override
protected void applyDrawTransform(DrawContext dc, SurfaceTileDrawContext sdc) {
super.applyDrawTransform(dc, sdc);
dc.getGL().getGL2().glRotated(-angle, 0, 0, 1);
}
}
