您想使用 anAttributedString
并将其传递iterator
给drawString
static String Background = "input.png";
static int curX = 10;
static int curY = 50;
public static void main(String[] args) throws Exception {
AttributedString word= new AttributedString("This is text. This should be BOLD");
word.addAttribute(TextAttribute.FONT, new Font("TimesRoman", Font.PLAIN, 18));
word.addAttribute(TextAttribute.FOREGROUND, Color.BLACK);
// Sets the font to bold from index 29 (inclusive)
// to index 33 (exclusive)
word.addAttribute(TextAttribute.FONT, new Font("TimesRoman", Font.BOLD, 18), 29,33);
word.addAttribute(TextAttribute.FOREGROUND, Color.BLUE, 29,33);
final BufferedImage image = ImageIO.read(new File(Background));
Graphics g = image.getGraphics();
g.drawString(word.getIterator(), curX, curY);
g.dispose();
ImageIO.write(image, "png", new File("output.png"));
}
输出.png:
