生成后打印图像[c#]

Question

我有以下方法加载空白模板图像,在其上绘制相关信息并将其保存到另一个文件.我想稍微改变一下以实现以下目标:

• 加载模板图像
• 在上面绘制相关信息
• 打印出来

我不想保存它,只需打印出来.这是我现有的方法:

public static void GenerateCard(string recipient, string nominee, string reason, out string filename)
    {
        // Get a bitmap.
        Bitmap bmp1 = new Bitmap("template.jpg");

        Graphics graphicImage;

        // Wrapped in a using statement to automatically take care of IDisposable and cleanup
        using (graphicImage = Graphics.FromImage(bmp1))
        {
            ImageCodecInfo jgpEncoder = GetEncoder(ImageFormat.Jpeg);

            // Create an Encoder object based on the GUID
            // for the Quality parameter category.
            Encoder myEncoder = Encoder.Quality;

            graphicImage.DrawString(recipient, new Font("Arial", 10, FontStyle.Regular), SystemBrushes.WindowText, new Point(480, 33));
            graphicImage.DrawString(WordWrap(reason, 35), new Font("Arial", 10, FontStyle.Regular), SystemBrushes.WindowText, new Point(566, 53));
            graphicImage.DrawString(nominee, new Font("Arial", 10, FontStyle.Regular), SystemBrushes.WindowText, new Point(492, 405));
            graphicImage.DrawString(DateTime.Now.ToShortDateString(), new Font("Arial", 10, FontStyle.Regular), SystemBrushes.WindowText, new Point(490, 425));
            EncoderParameters myEncoderParameters = new EncoderParameters(1);
            EncoderParameter myEncoderParameter = new EncoderParameter(myEncoder, 100L);
            myEncoderParameters.Param[0] = myEncoderParameter;

            filename = recipient + " - " + DateTime.Now.ToShortDateString().Replace("/", "-") + ".jpg";

            bmp1.Save(filename, jgpEncoder, myEncoderParameters);
        }
    }

希望你可以帮忙,布雷特

只需将其打印到打印机而不保存

这是我能想到的最简单的例子.

Bitmap b = new Bitmap(100, 100);
using (var g = Graphics.FromImage(b))
{
    g.DrawString("Hello", this.Font, Brushes.Black, new PointF(0, 0));
}

PrintDocument pd = new PrintDocument();
pd.PrintPage += (object printSender, PrintPageEventArgs printE) =>
    {
        printE.Graphics.DrawImageUnscaled(b, new Point(0, 0));
    };

PrintDialog dialog = new PrintDialog();
dialog.ShowDialog();
pd.PrinterSettings = dialog.PrinterSettings;
pd.Print();
