C#实现将Email地址转成图片显示的方法

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);
}

希望本文所述对大家的c#程序设计有所帮助。
