How to stream a PDF417 barcode?

Hello,

I am evaluating your ASP.NET Server Control for 2D barcodes. I need to generate a PDF417 barcode on the server and capture the stream output, which then gets used to generate a PDF document.

I currently have it working using this code:

Dim imageStream As System.IO.MemoryStream = New System.IO.MemoryStream()
Dim barcode As IDAutomation.PDF417ServerControl.PDF417Barcode = New IDAutomation.PDF417ServerControl.PDF417Barcode()
barcode.PDFErrorCorrectionLevel = 2
barcode.DataToEncode = barcodeData
barcode.ImageType = PDF417Barcode.ImageTypes.JPEG
barcode.PDFMode = PDF417Barcode.PDF417Modes.Text
barcode.ImageResolution = 600
Dim oBitmap As System.Drawing.Bitmap = barcode.GetBitmapImageForBinaryStream()

oBitmap.Save(imageStream, ImageFormat.Jpeg)

Is there a more direct way to capture the stream without using the Bitmap?

I see there is a PDF417StreamCS.dll. I prefer not to add an aspx page and just generate the barcode from existing class files.

Thank you.


Application: .NET

To use the method you describe, just reference the image file at the system level, where it is located.

Otherwise, to stream the image by a URL, you would use the ASP Page method.

Ultimately, both generate a reliable barcode image.

For specifics, please refer to the Manual page.
