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

java.awt.geom.AffineTransform.concatenate()
Concatenates an AffineTransform Tx to this AffineTransform Cx in the most commonly useful way to provide a new user space that is mapped to the former user space by Tx. Cx is updated to perform the combined transformation. 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 like this: Cx'(p) = Cx(Tx(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] = [this] x [Tx] 
```
@param Tx the AffineTransform object to beconcatenated with this AffineTransform object. @see #preConcatenate @since 1.2
