drawing a string vertical

[hannes]

Hey guys,

How can you draw a string vertical with java2d graphics?

thanks, Hannes

What have you tried so far?

I can think of two ways to do this.
First make an AffineTransform to rotate and translate the string to the desired position/angle.
Then you can either
1 — transform the graphics context with the transform, or
2 — create a transformed font using the Font deriveFont method.

In the case of the graphics approach you will need to save the original transform, use your AffineTransform in the Graphics2D transform method and finally, before exiting the paintComponent method restore the original transform with the setTransform method. This is important because the same graphics context can (will often) be passed along by the Container paint method for drawing borders and child components.

protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2 = (Graphics2D)g;
    AffineTransform orig = g2.getTransform();
    AffineTransform at = ...
    g2.transform(at);  // concatenates with orig transform
    g2.draw(String(...);
    g2.setTransform(orig);  // resets to original
}
