本文实例讲述了C#实现将Email地址转成图片显示的方法。分享给大家供大家参考。具体实现方法如下：
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);
}
