Is there a way to add watermark invoice into PDF file?

Hi Team,
I have a requirement to add watermark invoice into PDF when customer make a purchase of soft copy. Is there any plug in?
Appreciate any advice! Thanks...

Hi,

Yes we can add watermark to exported PDF, It will require small code changes.

NopCommerce is using iTextSharp for generating PDF files. You can refer to iTextSharp's documentation for adding watermark in exporting pdf.

For testing purpose, I've updated code in NopCommerce 3.70.

..\Libraries\Nop.Services\Common\PdfService.cs

Method Name:
public virtual void PrintOrdersToPdf(Stream stream, IList<Order> orders, int languageId = 0)

Added new line in code.

string watermarkText = "NopCommerce PDF Watermark";
                ColumnText.ShowTextAligned(pdfWriter.DirectContent, Element.ALIGN_CENTER, new Phrase(watermarkText, font), 300, 400, 45);

Exported PDF Invoice of test order.





Hope this helps.

Thanks,
Ajay

Hi Ajay,
Thanks for your advice. Actually, what we need is not to create a new pdf with watermark.
We already have PDF, so called e-book. Once user made a payment for e-book, we would like to add invoice number watermark on the existing e-book PDFs. Hope to get some advice from you. Thanks.

Han

Actually this is not possible in core code.
