Creates an entry in the Graphics state stack. Each call to pushState() should be paired with a call to popState(). Any changes to the Graphics object between the calls will be flushed after the popState().

Overrides:

pushState in class Graphics

See Also:

popState

  public void popState()

Restores the Graphics object to its condition before the most recent pushState() call. All fonts, colors, clipping rectangles and translations will be restored.

Overrides:

  public void translate(int x,
                        int y)

Alters the coordinate system so that all drawing, filling, and clipping operations implicitly have x and y added to their positions. If there is any current translation, the total translation is the sum of the old and new translations.
