public string CreateQrCode(string md5Str,string name,int sex) { string str = sex == 1? "先生":"女士"; string logoPath = AppDomain.CurrentDomain.BaseDirectory + "/logo.png"; string qrCodePath = path + DateTime.Now.ToString("yyyyMMddHHmmss") + ".jpg"; string yqPath = AppDomain.CurrentDomain.BaseDirectory + "/yq2.jpg"; string yqCardPath = path + TCommon.Md5(DateTime.Now.ToString("yyyyMMddHHmmss")) + ".jpg"; if (Directory.Exists(path) == false)//如果不存在就创建file文件夹 { Directory.CreateDirectory(path); } Generate3(md5Str,logoPath,qrCodePath); Image qrCodeImg = new Bitmap(qrCodePath); Image image = new Bitmap(yqPath); Graphics ig = Graphics.FromImage(image); Font font = new Font("Arial", 38,FontStyle.Bold); Font font2 = new Font("STXINWEI", 38, FontStyle.Bold); Brush brush = System.Drawing.Brushes.Black; SizeF size = ig.MeasureString(name, font2); SizeF size2 = ig.MeasureString(str, font); ig.DrawString(name, font, brush, (720-size.Width-size2.Width) /2, 680); ig.DrawString(str, font, brush, (720 - size.Width - size2.Width) / 2 + size.Width, 680); ig.FillRectangle(Brushes.White, 280, 351, 160, 160); ig.DrawImage(qrCodeImg, 285, 356); image.Save(yqCardPath); return yqCardPath.Substring(2); } 图片上生成文字
