Examples of java.awt.Graphics2D.transform()

java.awt.Graphics2D.transform()
Composes an AffineTransform object with the Transform in this Graphics2D according to the rule last-specified-first-applied. If the current Transform is Cx, the result of composition with Tx is a new Transform Cx'. Cx' becomes the current Transform for this Graphics2D. Transforming a point p by the updated Transform Cx' is equivalent to first transforming p by Tx and then transforming the result by the original Transform Cx. In other words, Cx'(p) = Cx(Tx(p)). A copy of the Tx is made, if necessary, so further modifications to Tx do not affect rendering. @param Tx the AffineTransform object to be composed with the current Transform @see #setTransform @see AffineTransform
