How to convert ZXingBarcodeImageView to a PDFImage?

Question

I am trying to convert my ZXingBarcodeImageView to a PDFImage to print it using SyncFusion? Is there a way I can access the image of a ZXingBarcodeImageView to draw in a PDF. I am using Syncfusion PDF to draw out my barcode.

Thank you in advance!

We can't convert ZXingBarcodeImageView to PdfImagedirectly.

Check the documentation of PdfImage .

FromFile -- Creates PdfImage from the specified file

FromImage -- Creates a PdfImage from the existing System.Drawing.Image.

FromStream -- Creates PdfImage from the specified data stream

You could try to save ZXingBarcodeImageView into local path , convert it to Image , get its stream and so on ..

Is there a way I could directly convert ZXingBarcodeImageView to a regular System.Drawing.Image? I don't need to save it locally, really I'm just trying to print the barcode in my PDF. – Mochi Jun 05 '19 at 21:16

I followed this link to create a BarcodeService interface and implement it in both platforms. I then convert that Stream to PDFBitmap to draw in my PDF (code below).

using (PdfDocument document = new PdfDocument())
        {
            document.PageSettings.Size = new SizeF(612, 350);
            document.PageSettings.Orientation = PdfPageOrientation.Landscape;
            document.PageSettings.SetMargins(0);
            // Add a page to the document
            PdfPage page = document.Pages.Add();

            //Create PDF graphics for the page
            PdfGraphics graphics = page.Graphics;
            var qrImage = DependencyService.Get<IBarcodeService>().ConvertImageStream(Vin);
            PdfBitmap image = new PdfBitmap(qrImage);

            graphics.DrawImage(image, 300, -50, 350, 350);
        }

and Viola!
