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? Thank you very much.
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
):
