Examples of java.awt.Graphics2D.translate()

java.awt.Graphics2D.translate()
Translates the origin of the Graphics2D context to the point (x, y) in the current coordinate system. Modifies the Graphics2D context so that its new origin corresponds to the point (x, y) in the Graphics2D context's former coordinate system. All coordinates used in subsequent rendering operations on this graphics context are relative to this new origin. @param x the specified x coordinate @param y the specified y coordinate @since JDK1.0
