How to Convert PostScript Files to PDF and Add Barcodes/QR Codes Using VeryPDF PostScript to PDF Converter and PDFStamp Command Line SDK Tools

Posted on Author VeryPDF / 1186 Views

Working with PostScript (PS) files is common in many Windows printing environments.
Often, organizations need to convert these PS files into more portable formats like PDF,
and then enhance them by adding barcodes or QR codes for tracking, authentication, or identification purposes.

This article introduces two professional solutions from VeryPDF that can help you achieve this workflow in just two steps:

  1. Convert PostScript (PS) to PDF
  2. Add barcode/QR code (or any image/text stamp) to the resulting PDF

Both solutions are available as command line tools and SDKs,
making them suitable for automation, batch processing, or integration into custom applications (such as a C# project).

How to Convert PostScript Files to PDF and Add Barcodes/QR Codes Using VeryPDF PostScript to PDF Converter and PDFStamp Command Line SDK Tools

Step 1: Convert PS to PDF with VeryDOC Postscript to PDF Converter

Product link: VeryDOC Postscript to PDF Converter

VeryDOC Postscript to PDF Converter is a reliable tool for converting PostScript (PS) and Encapsulated PostScript (EPS)
files into high-quality PDF documents. It is designed to run as a standalone application without requiring third-party software.

Key Features:

  • Fast and accurate conversion from PS/EPS to PDF.
  • Support for encryption, password protection, and metadata editing.
  • Page range selection and rotation options.
  • Ability to merge multiple PDFs into one.
  • SDK available for integration into software projects.

Command Line Examples:

ps2pdf.exe C:\input.ps
ps2pdf.exe C:\input.ps C:\output.pdf
ps2pdf.exe -firstpage 1 -lastpage 20 C:\input.ps C:\output.pdf
ps2pdf.exe -subject "subject" C:\in.ps C:\out.pdf
ps2pdf.exe -producer "producer" C:\in.ps C:\out.pdf
ps2pdf.exe -creator "creator" C:\in.ps C:\out.pdf
ps2pdf.exe -ownerpwd owner -keylen 2 -encryption 3900 C:\in.ps C:\out.pdf
ps2pdf.exe -mergepdf "C:\1.pdf|C:\2.pdf|C:\3.pdf" C:\out.pdf
ps2pdf.exe -burstpdf C:\input.pdf C:\output.pdf
ps2pdf.exe -rotate 90 C:\input.ps C:\output.pdf
ps2pdf.exe -pdf2ps C:\input.pdf C:\output.ps
ps2pdf.exe -noempty C:\input.ps C:\output.pdf

Step 2: Add Barcode/QR Code with VeryPDF PDF Stamp

Product link: VeryPDF PDF Stamp Command Line

Once you have a PDF file, you can use the VeryPDF PDF Stamp tool to insert images (such as barcodes or QR codes) into the document.
This utility supports precise placement, rotation, scaling, transparency, and even multiple stamps on the same page.

Key Features:

  • Add images (JPG, PNG, BMP, etc.) as stamps.
  • Insert text with custom fonts, colors, and sizes.
  • Flexible positioning (top, bottom, left, right, center).
  • Support for multiple stamps on a single page.
  • Full control via command line and SDK.

Command Line Examples:

Image Stamp Example (barcode/QR in top-right corner):

pdfstamp.exe -PDF "output.pdf" -o "final.pdf" -AI "qrcode.png" -p2 -mlr-30 -mtb30

Step 3: Automating with C#

Since both tools are command line based, you can easily integrate them into your C# applications
using the System.Diagnostics.Process class.

Here’s a simple example that first converts a .ps file into .pdf,
and then stamps a QR code image into the top-right corner of the PDF: 

using System;
using System.Diagnostics;

class Program
{
    static void RunCommand(string exePath, string arguments)
    {
        ProcessStartInfo psi = new ProcessStartInfo
        {
            FileName = exePath,
            Arguments = arguments,
            RedirectStandardOutput = true,
            RedirectStandardError = true,
            UseShellExecute = false,
            CreateNoWindow = true
        };

        using (Process process = new Process())
        {
            process.StartInfo = psi;
            process.Start();
            string output = process.StandardOutput.ReadToEnd();
            string error = process.StandardError.ReadToEnd();
            process.WaitForExit();

            Console.WriteLine("Output: " + output);
            if (!string.IsNullOrEmpty(error))
            {
                Console.WriteLine("Error: " + error);
            }
        }
    }

    static void Main()
    {
        string ps2pdfPath = @"C:\verypdf\ps2pdf.exe";
        string pdfstampPath = @"C:\verypdf\pdfstamp.exe";

        string inputPs = @"C:\input.ps";
        string outputPdf = @"C:\output.pdf";
        string finalPdf = @"C:\final.pdf";
        string qrCodeImage = @"C:\qrcode.png";

        // Step 1: Convert PS to PDF
        RunCommand(ps2pdfPath, $"\"{inputPs}\" \"{outputPdf}\"");

        // Step 2: Stamp QR Code in top-right corner
        RunCommand(pdfstampPath, $"-PDF \"{outputPdf}\" -o \"{finalPdf}\" -AI \"{qrCodeImage}\" -p2 -mlr-30 -mtb30");

        Console.WriteLine("Process completed successfully!");
    }
}

How this works:

  • ps2pdf.exe converts the PostScript file into a PDF.
  • pdfstamp.exe places the QR code image in the top-right corner of the PDF.
  • The RunCommand helper function handles command execution and captures output/errors.

Conclusion
