Bad rendering of java fonts

[Tristan]

Hi,

if I let a string slowly zoom out in Java the rendering is somehow
bad. The string shakes while becoming bigger.
Can I do anything about it ?
I use the drawString(String str, int x, int y) method to set the
string on the screen. In the same loop I derive a new font with
deriveFont(float size) and additional 0.2f for the current string size
for each step.
Is it any better to use the scale method of graphics instead ?

Thanks,

Tris.

P.S.: I dont't want to use image scaling.
