Drawing Text In Java

[Chase Preuninger]

BufferedImage img = new BufferedImage(50 * text.length(), 100,
BufferedImage.TYPE_3BYTE_BGR);

Graphics2D g = img.createGraphics();
FontMetrics fm = g.getFontMetrics(f);

g.setBackground(Color.WHITE);
g.clearRect(0, 0, img.getWidth(), img.getHeight());

g.setFont(f);
g.setColor(Color.BLACK);
g.drawString(text, 50, fm.getAscent() + 10);

How can I tell how big to make my image based on the font and text?

The API pretty much covers it at the pixel level:

Alternatively, TextLayout offers a convenient abstraction:

<http://java.sun.com/javase/6/docs/api/java/awt/font/TextLayout.html>

Perhaps you can explain more about your goal and provide a short example
of where you're having trouble: <http://pscode.org/sscce.html>

That is an artistic decision. You can use FontMetrics to get some idea
how my some given String really is.

But gow can I create a FontMetrics if I don't have a graphics until
after I create the image and therefore can't get the fontrendercontext?

You might try hiring someone with the faintest clue.
(Just a thought.)
