How to add text to an image in java?

Question

I need to add some texts to an existing table image (png). Which means that I need to "write" on the image and I need the option to select the text location. How can I do it?

Answer 1

It's easy, just get the Graphics object from the image and draw your string onto the image. This example (and output image) is doing that:

public static void main(String[] args) throws Exception {     final BufferedImage image = ImageIO.read(new URL(         "http://upload.wikimedia.org/wikipedia/en/2/24/Lenna.png"));      Graphics g = image.getGraphics();     g.setFont(g.getFont().deriveFont(30f));     g.drawString("Hello World!", 100, 100);     g.dispose();      ImageIO.write(image, "png", new File("test.png")); } 

Output (test.png):
