我要评论本文实例讲述了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。
