String length in pixels in Java

Question

Is there a way to calculate the length of a string in pixels, given a certain java.awt.Font object, that does not use any GUI components?

Answer 1

This gives the output of (137.0, 15.09375) for me. I have no idea what the units are, but it certainly looks proportionally correct and doesn't use Graphics2D directly.

    Font f = new Font("Ariel", Font.PLAIN, 12);
    Rectangle2D r = f.getStringBounds("Hello World! Hello World!", new FontRenderContext(null, RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT, RenderingHints.VALUE_FRACTIONALMETRICS_DEFAULT));
    System.out.println("(" + r.getWidth() + ", " + r.getHeight() + ")");
