java Graphics绘制水印效果如何使得字体倾斜。谢谢大神

Question

在图片上面利用Graphics中的drawstring如何使得字体倾斜，各位大神帮帮忙哟。
即，把文本信息输入到图片上，形成水印的效果。

中间那块代码
@SuppressWarnings("restriction")
public void fontImg(String imgPath,String newPath, String text, Font font, Color color, int left, int top) {
try {
char[] chrCharArray;
BufferedImage src = ImageIO.read(new File(imgPath));
int width = src.getWidth();
int height = src.getHeight();
BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
Graphics graph = image.createGraphics();
graph.drawImage(src, 0, 0, width, height, null);
graph.setColor(color); graph.setFont(font);
chrCharArray=text.toCharArray();
top=height/2+40;
left=width/3;
for(int i=0;i<chrCharArray.length;i++)
{
graph.drawString(""+chrCharArray[i]+"".toString(), left, top);
left+=8; top-=3;
}
graph.dispose();
FileOutputStream out = new FileOutputStream(newPath);
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(image);
out.close();
image.flush();
src.flush();
} catch (Exception e) {
e.printStackTrace();
}
}
