Print image after it's been generated [c#]
I have the following method that loads in a blank template image, draws the relevant information on it and saves it to another file. I want to change this slightly to achieve the following:
- load in the template image
- draw the relevant information on it
- print it
I don't want to save it, just print it out. Here's my existing method:
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));
开发者_Python百科 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);
}
}
Hope you can help, Brett
Just print it to the printer without saving
This is the most simple example I could come up with.
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();
When you use the PrintDocument class, you can print without needing to save the image.
var pd = new PrintDocument();
pd.PrintPage += pd_PrintPage;
pd.Print()
And in the pd_PrintPage eventhandler:
void pd_PrintPage(object sender, PrintPageEventArgs e)
{
Graphics gr = e.Graphics;
//now you can draw on the gr object you received using some of the code you posted.
}
NOTE: Don't dispose the Graphics object you received in the eventhandler. This is done by the PrintDocument object itself...
Use the PrintPage event;
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e) {
e.Graphics.DrawImage(image, 0, 0);
}
