本文實例講述了C#完成將Email地址轉成圖片顯示的辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

private final static IndexColorModel icm = createIndexColorModel();
/**
 * 生成電子郵件圖片
 * @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));//通明
  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);
}
