Examples of ae.java.awt.geom.AffineTransform.translate()

ae.java.awt.geom.AffineTransform.translate()
Concatenates this transform with a translation transformation. This is equivalent to calling concatenate(T), where T is an AffineTransform represented by the following matrix:
```
 [   1    0    tx  ] [   0    1    ty  ] [   0    0    1   ] 
```
@param tx the distance by which coordinates are translated in theX axis direction @param ty the distance by which coordinates are translated in theY axis direction @since 1.2
