Can I set the DPI resolution of my Java Swing application without changing the systems' DPI setting?

Question

I have a Java application using the Substance LookAndFeel with Windows as the the target platform and I want to increase the DPI setting of my application without chang

Don't know if that is possible. The look&feel would have to support it, and as far as I know, the Windows Look&Feel does not. Here's a hack which you may consider: Iterate through all the fonts defined in your look&feel and redefine them to be slighly bigger. Here is a code snippet that does this:

for (Iterator i = UIManager.getLookAndFeelDefaults().keySet().iterator(); i.hasNext();) {
    String key = (String) i.next();
    if(key.endsWith(".font")) {
        Font font = UIManager.getFont(key);
        Font biggerFont = font.deriveFont(2.0f*font.getSize2D());
        // change ui default to bigger font
        UIManager.put(key,biggerFont);
    }
}

I suppose you could take this one step further and redefine scale borders proportionally as well, but that gets very complicated very quickly
