[SOLVED] How do i render wrapped text on an image in java

How do i render wrapped text on an image in java

Using Java, is there any built-in way to render text so that its limited to a rectangle on a graphics2D object?

I know I can use Graphics2D.drawString but it only draws a sinlge line of text.

I also know that I can use

FontMetrics fm= graphics.getFontMetrics(font);
Rectangle2D rect=fm.getStringBounds("Some Text",graphics);

to get the information about the bounds of a string when rendered using some Font font on some Graphics2D graphics object.

So I could start looping, breaking my string and so on to force it to fit inside some rectangle.

But I would much prefer not to have to write those...

Is there any ready made function that will do this for me?

Solution

Use temporary JTextArea to do perfect line wrapping with ~10 lines of code:

static void drawWrappedText(Graphics g, String text, int x, int y, int w, int h) {
    JTextArea ta = new JTextArea(text);
    ta.setLineWrap(true);
    ta.setWrapStyleWord(true);
    ta.setBounds(0, 0, w, h);
    ta.setForeground(g.getColor());
    ta.setFont(g.getFont());
    Graphics g2 = g.create(x, y, w, h); // Use new graphics to leave original graphics state unchanged
    ta.paint(g2);
}
