in that same app, i'm rendering text using a JTextPane. here is a sample:

can you notice how the lower sample is a little 'smudged'? well, i can't figure out how to make it look like the upper sample.

update:

• System.setProperty("awt.useSystemAAFontSettings","false") and "lcd" too aren't working.
• ((Graphics2D)g).setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_OFF) in paint() isn't working
• putClientProperty(sun.swing.SwingUtilities2.AA_TEXT_PROPERTY_KEY, Boolean.TRUE) gives java.lang.ClassCastException: java.lang.Boolean cannot be cast to sun.swing.SwingUtilities2$AATextInfo

Answer 1

If you want your result to look like the the upper sample, then you want to disable anti-aliasing.

The first sample in your question has anti-aliasing disabled and the second sample has it enabled.

According to http://mindprod.com/jgloss/antialiasing.html the following code should help:

jtextArea.putClientProperty(com.sun.java.swing.SwingUtilities2.AA_TEXT_PROPERTY_KEY, Boolean.TRUE);

Notice that the reference to com.sun.java.* will make your application non-portable to non-Sun JVMs (and possibly to different versions of Sun JVMs).

Answer 2

putClientProperty(SwingUtilities2.AA_TEXT_PROPERTY_KEY, null);
