Examples of java.awt.Graphics.translate()

java.awt.Graphics.translate()
Translates the origin of the graphics context to the point (x, y) in the current coordinate system. Modifies this graphics context so that its new origin corresponds to the point (x, y) in this graphics context's original coordinate system. All coordinates used in subsequent rendering operations on this graphics context will be relative to this new origin. @param x the x coordinate. @param y the y coordinate.

    Graphics g = painter.getGraphics();
    g.translate(x, y);
    Value pull = getPullValue(painter.getAttributeSet());
    Value actual = painter.getPort(0);
    paintBase(painter, pull, pull.getColor(), actual.getColor());
    g.translate(-x, -y);
    painter.drawPorts();
  }
  
  private void paintBase(InstancePainter painter, Value pullValue,
      Color inColor, Color outColor) {
