Examples of java.awt.Graphics2D.scale()

java.awt.Graphics2D.scale()
Concatenates the current Graphics2D Transform with a scaling transformation Subsequent rendering is resized according to the specified scaling factors relative to the previous scaling. This is equivalent to calling transform(S), where S is an AffineTransform represented by the following matrix:
```
 [   sx   0    0   ] [   0    sy   0   ] [   0    0    1   ] 
```
@param sx the amount by which X coordinates in subsequentrendering operations are multiplied relative to previous rendering operations. @param sy the amount by which Y coordinates in subsequent rendering operations are multiplied relative to previous rendering operations.
