Putting text in an image file

Hi!
How can we put some text in an image file using Java?
I have a String and I want to put this String in an image file (.gif, .bmp, .jpg or any other).
Any help would be appreciated.

Thank you.

You certainly can write text into an image in Java, and you can write the result into a file in some popular image formats.

However, if, as posting in the beginner forum suggests, you are new to Java, this might not be a good choice for your first Java program!

You can use javax.imageio.ImageIO class to read and write the image.

To write text into the image, you need to get it as a BufferedImage. Then get a Graphics2D from your BufferedImage. Then you can use Graphics2D.drawString() to write text. You may wish to set the Font and Color of the Graphics2D before writing the text. A FontMetrics object can be used to find out how big the text will be.

I agree that this may not be the best topic for a beginner to cut his teeth on, but here's Sun's tutorial: http://java.sun.com/docs/books/tutorial/2d/index.html
