Description Florian Thienel CLA 2007-03-15 06:51:27 EDT 
Build ID: M20070212-1330

Steps To Reproduce:
1. call ScaleableLayeredPane.setScale() with a scale > 1.0d
2. call ScaleableLayeredPane.getPreferredSize()

The preferred size gets smaller, not bigger. The same with minimum size and maximum size.

More information:
The method getPreferredSize(int, int) divides by the scale and does not multiply by the scale:
Dimension d = super.getPreferredSize((int) (wHint / getScale()), (int)(hHint / getScale()));

should be:
Dimension d = super.getPreferredSize((int) (wHint * getScale()), (int)(hHint * getScale()));

The same with getMinimumSize(int, int) and getMaximumSize(int, int)

It is only dividing the hints by the scale, which seems to make sense to me.

Hm. I did some further investigation and think the calculation is not the problem. So please forget this bug... Sorry
