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

java.awt.geom.AffineTransform.scale()
Concatenates this transform with a scaling transformation. This is equivalent to calling concatenate(S), where S is an AffineTransform represented by the following matrix:
```
 [   sx   0    0   ] [   0    sy   0   ] [   0    0    1   ] 
```
@param sx the factor by which coordinates are scaled along the X axis direction @param sy the factor by which coordinates are scaled along theY axis direction @since 1.2
