Examples of java.awt.geom.AffineTransform.preConcatenate()

java.awt.geom.AffineTransform.preConcatenate()
Concatenates an AffineTransform Tx to this AffineTransform Cx in a less commonly used way such that Tx modifies the coordinate transformation relative to the absolute pixel space rather than relative to the existing user space. Cx is updated to perform the combined transformation. Transforming a point p by the updated transform Cx' is equivalent to first transforming p by the original transform Cx and then transforming the result by Tx like this: Cx'(p) = Tx(Cx(p)) In matrix notation, if this transform Cx is represented by the matrix [this] and Tx is represented by the matrix [Tx] then this method does the following:
```
 [this] = [Tx] x [this] 
```
@param Tx the AffineTransform object to beconcatenated with this AffineTransform object. @see #concatenate @since 1.2

  Tx.preConcatenate(AffineTransform.getTranslateInstance
        (canvasSize.width/2, canvasSize.height/2));
  // take into account the initial transform
  AffineTransform newRT = new AffineTransform(at);
  newRT.preConcatenate(Tx);
  // change the rendering transform
  svgCanvas.setRenderingTransform(newRT);
