将重复的文本水印添加到代号为1的图像上

Question

是否可以使用Codename One API向图像添加重复的文本作为水印？

例如，给一个图像和一个或多个单词的文本，我想创建一个新的图像，如下所示：

Answer 1

确保只使用可变的图像：

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
