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

            // transform the AOI into the image's coordinate system
            aoi = Px.createTransformedShape(aoi).getBounds2D();
            AffineTransform Mx = new AffineTransform();
            double sx = width / aoi.getWidth();
            double sy = height / aoi.getHeight();
            Mx.scale(sx, sy);
            double tx = -aoi.getX();
            double ty = -aoi.getY();
            Mx.translate(tx, ty);
            // take the AOI transformation matrix into account
            // we apply first the preserveAspectRatio matrix
