I don't believe that the Java 2D API has a resolution independent mapping
mode.
In order to ensure that your on-screen graphics have the size that you want,
I think you can use
Toolkit.getScreenResolution()
to get the current number of pixels per inch, then adjust your pixel
measurements accordingly.

Subject: [JAVA2D] User space - device space conversion
