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：
privatefinalstaticIndexColorModelicm=createIndexColorModel();
/**
*生成电子邮件图片
*@paramemail
*@paramout
*@throwsIOException
*/
publicstaticvoidMakeEmailImage(Stringemail,OutputStreamout)throwsIOException{
intheight=22;
BufferedImagebi=newBufferedImage(255,height,BufferedImage.TYPE_INT_RGB);
Graphics2Dg=(Graphics2D)bi.getGraphics();
FontmFont=newFont("Verdana",Font.PLAIN,14);
g.setFont(mFont);
g.drawString(email,2,19);
FontMetricsfm=g.getFontMetrics();
intnew_width=fm.charsWidth(email.toCharArray(),0,email.length())+4;
intnew_height=fm.getHeight();
BufferedImagenbi=newBufferedImage(new_width,new_height,BufferedImage.TYPE_BYTE_INDEXED,icm);
Graphics2Dg2=(Graphics2D)nbi.getGraphics();
g2.setColor(newColor(0,0,0,0));//透明
g2.fillRect(0,0,new_width,new_height);
g2.setFont(mFont);
g2.setColor(newColor(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。
