  Hello,
  
  You may export your report that contain barcodes, into the image file (bmp, png, ...). Is this what you want?

  Well, it would be prefered to be a memory bitmap, the situation is there's a report with barcodes on, and this report has a matching document in another piece of software, my software can open these files and past images into it and I'd like to be able to paste a barcode on the document (using code) so it can be matched to the report.
  
  Here's a snip of the type of code I'd like to be able to use
  
  
  BarcodeGenerator Barcode = new Barcode("123456789");
  Barcode.Symbiology = "Code39";
  Bitmap barcodeImage = (Bitmap)Barcode.GetImage();
  
  //Copy the barcode image into Clipboard
  Clipboard.SetDataObject(barcodeImage);
  
  Then I can paste it from the clipboard into the app.
  
  I'd really like to avoid using temp files, if the above is not possible, hwo about the ability to have a Report.GetOutputAsBitmaps() which returns a report as an array of Bitmaps, then I can make a small report into memory bitmap?
  
  Many thanks,

  You can use the following code:
  

        BarcodeObject barcode = new BarcodeObject();
        barcode.SymbologyName = "Code39";
        barcode.Text = "123456789";
        barcode.Height = 64;
  
        // to get actual width, we must draw the barcode first
        using (Bitmap tempBmp = new Bitmap(1, 1))
        using (Graphics g = Graphics.FromImage(tempBmp))
        using (GraphicCache cache = new GraphicCache())
        {
          barcode.Draw(new FRPaintEventArgs(g, 1, 1, cache));
        }
  
        // now we know width and height, perform the drawing
        Bitmap bmp = new Bitmap((int)barcode.Width, (int)barcode.Height);
        using (Graphics g = Graphics.FromImage(bmp))
        using (GraphicCache cache = new GraphicCache())
        {
          g.Clear(Color.White);
          barcode.Draw(new FRPaintEventArgs(g, 1, 1, cache));
        }
  
        bmp.Save(...);

  Fantastic, I'll try that!
  
  Next question,
  I don't think fast reports supports Databar barcodes, one of which (Databar Expanded), in a small amount of space can fit 41 alphanumeric characters! (or 74 digits!)
  
  http://mdn.morovia.com/manuals/databar-fontware/ch02s02.php
  
  They provide free sample software (with c source code) here:
  
  http://www.gs1.org/barcodes/databar/software
  (http://www.gs1.org/sites/default/files/docs/barcodes/databar/GS1_DataBar_Software.zip)
  
  Would it be possible to build support in for fast reports?
  
  If not, is code128 the most compact barcode?
  
  Many thanks,

  Sorry, it requires too much efforts to implement it. We don't have such plans in the near future.

  Ok,
  
  no problem, but could you tell me which barcode that fast report supports fits most data into a small space? I think code128 is compact, but are any other's better?

  Hello,
  
  You may look at 2D barcodes such as PDF417 and DataMatrix.

  I myself came across the same problem and found that DataMatrix barcodes were definatly the best to use as barcode labels. Dont get me wrong thePDF417 are ok but my personal preference is the DataMatrix

  Does anyone have a snippet for pdf417 Barcode. I'm new to FastReports, it would be greatly appreciated.
