C#实现将Email地址转成图片显示的方法

private final static IndexColorModel icm = createIndexColorModel();/** * 生成电子邮件图片 * @param email * @param out * @throws IOException */public static void MakeEmailImage(String email, OutputStream out) throws IOException {  int height = 22;  BufferedImage bi = new BufferedImage(255,height,BufferedImage.TYPE_INT_RGB);      Graphics2D g = (Graphics2D)bi.getGraphics();  Font mFont = new Font("Verdana", Font.PLAIN, 14);  g.setFont(mFont);  g.drawString(email, 2, 19);  FontMetrics fm = g.getFontMetrics();  int new_width = fm.charsWidth(email.toCharArray(), 0, email.length()) + 4;  int new_height = fm.getHeight();  BufferedImage nbi = new BufferedImage(new_width, new_height, BufferedImage.TYPE_BYTE_INDEXED, icm);  Graphics2D g2 = (Graphics2D)nbi.getGraphics();  g2.setColor(new Color(0,0,0,0));//透明  g2.fillRect(0,0,new_width,new_height);  g2.setFont(mFont);  g2.setColor(new Color(200,0,0));  g2.drawString(email, 2, new_height-4);  ImageIO.write(nbi, "gif", out);}
