C#打印图片

打印的原理是:生成mdi文件,系统碰到mdi的时候会自动以打印的方式处理。所以,不管用什么模板,什么方式;能在PrintPage事件处理中,生成一张要打印内容的图片就OK了! C#实现打印源码如下: #region 打印 private void btnPrint_Click(object sender, EventArgs e) { //打印预览 //PrintPreviewDialog ppd = new PrintPreviewDialog(); PrintDocument pd = new PrintDocument(); //设置边距 Margins margin = new Margins(20, 20, 20, 20); pd.DefaultPageSettings.Margins = margin; ////纸张设置默认 //PaperSize pageSize = new PaperSize("First custom size", 800, 600); //pd.DefaultPageSettings.PaperSize = pageSize; //打印事件设置 pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage); //ppd.Document = pd; //ppd.ShowDialog(); try { pd.Print(); } catch (Exception ex) { MessageBox.Show(ex.Message, "打印出错", MessageBoxButtons.OK, MessageBoxIcon.Error); pd.PrintController.OnEndPrint(pd, new PrintEventArgs()); } } //打印事件处理 private void pd_PrintPage(object sender, PrintPageEventArgs e) { string date = lblDate.Text; //当前日期 string flowId = lblFlowId.Text; //流水号 string payDate = PayDate.Year.ToString() + "年" + PayDate.Month.ToString() + "月"; //应收年月 string adminId = lblAdminId.Text; //操作员编号 string baseExpense = lblBaseExpense.Text; //应交基本费用 string fine = lblFine.Text; //罚款数目 string upExpense = lblUpExpense.Text; //上月上余 string actualExpense = txtActualExpense.Text; //实际应交费用 string chineseExpense = DecimalToChinese.ConvertSum(actualExpense); //实际应交费用的中文大写 //读取图片模板 Image temp = Image.FromFile(@"Receipts.jpg"); GetResultIntoImage(ref temp, UserId, flowId, date, baseExpense, fine, upExpense, actualExpense, chineseExpense, payDate, adminId); int x = e.MarginBounds.X; int y = e.MarginBounds.Y; int width = temp.Width; int height = temp.Height; Rectangle destRect = new Rectangle(x, y, width, height); e.Graphics.DrawImage(temp, destRect, 0, 0, temp.Width, temp.Height, System.Drawing.GraphicsUnit.Pixel); } /// /// 将收费结果填充到图片模板 /// private void GetResultIntoImage( ref Image temp, string userId, string flowId, string currentDate, string baseExpense, string fine, string upExpense, string actualExpense, string chineseExpense, string payDate, string adminName) { //读取图片模板 Graphics g = Graphics.FromImage(temp); Font f = new Font("宋体", 12); Brush b = new SolidBrush(Color.Black); //填充数据到图片模板(位置要在制作图片模板的时候度量好) g.DrawImage(temp, 0, 0, temp.Width, temp.Height); g.DrawString(userId, f, b, 168, 105); g.DrawString(UserName, f, b, 166, 134); g.DrawString(flowId, f, b, 535, 105); g.DrawString(currentDate, f, b, 535, 134); g.DrawString(baseExpense, f, b, 219, 202); g.DrawString(fine, f, b, 372, 202); g.DrawString(upExpense, f, b, 486, 202); g.DrawString(actualExpense, f, b, 596, 202); g.DrawString(chineseExpense, f, b, 196, 238); g.DrawString(payDate, f, b, 176, 269); g.DrawString(adminName, f, b, 497, 298); g.Dispose(); } #endregion
