java水印的时候怎么设置文字倾斜度

public class exp2{ public static void main(String args[]){ int i=0

math mymath = new math()for(i=2i<=200i++) if(mymath.iszhishu(i)==true)

System.out.println(i)

}

class ImagePanel2a extends JPanel

{

/**

* 图像面板类

*/

....................................

String st = "水印"

BufferedImage image = null

public void paintComponent(Graphics g)

{

super.paintComponent(g)

Graphics2D g2 = (Graphics2D) g

if (image != null)

{

g2.drawImage(image, 0, 0, this)

g2.setColor(Color.green)//设置水印颜色

g2.drawString(st, 10, 10)//绘制水印，具体水印绘制方式根据自己的需求修改

}

.........

}

.................

}

/**

*保存添加水印后的图片

*

*/

......

BufferedImage bi = new BufferedImage(ImagePanel2a.getWidth(), ImagePanel2a.getHeight(), BufferedImage.TYPE_INT_ARGB)

Graphics2D g2d = bi.createGraphics()

ImagePanel2a.paint(g2d)

ImageIO.write(bi, "PNG", new File("路径"))
