Add a repeated text watermark to an image with Codename One

Question

Is it possible to add a repeated text as watermark to an Image using the Codename One API?

For example, giving an Image and a text of one or more words, I'd like to create a new Image like this:

Answer 1

Sure just use a mutable image:

Image watered = Image.create(sourceImg.getWidth(), sourceImg.getHeight());
Graphics g = watered.getGraphics();
g.drawImage(sourceImg, 0, 0);
g.setAlpha(30);
g.setColor(0xcccccc);
g.rotate(Math.PI / 2, sourceImg.getWidth() / 2, sourceImg.getHeight() / 2);


// here you can loop and do draw String a lot and just move with string width/height

// or you can use multiple drawImage calls and have a ready made watermark
// this might actually look better and won't require the alpha/rotation code
