When scale with AffineTransform, the size is correct but the x, y is not...

Question

When I scale wither an image or some text by adding an AffineTrasnform.getScaleInstance(double sx, double sy), the size of the text or image is correct. however, it does not properly place the x, y. For example:
1. Original background image: 284, 213
2. Original x, y = 35, 35
3. Scaled background image: 700, 525
4. Scaled x, y: 94, 112
That is incorrect. The x should have been 86 and y should have been 86. Why are they being translated to 94 and 112?
My AffineTransform:
AffineTransform scaleTransform = AffineTransform.getScaleInstance( 2.464788732394366, 2.464788732394366 );

So where is your SSCCE?To see how it's off, check the pixel spots in photoshop. Scale the original "Some String" to the proper size and you'll see it ends up in a slightly different spot.
