A .NET library to convert PDF files (and bitmaps) into Zebra Programming Language commands.

This .NET library is built on top of

You can use Labelary Online ZPL Viewer to render the resulting ZPL code.

Getting started

Just call one of the following static methods:

  • PDFtoZPL.Conversion.ConvertPdfPage()
  • PDFtoZPL.Conversion.ConvertPdf()
  • PDFtoZPL.Conversion.ConvertPdfAsync()
  • PDFtoZPL.Conversion.ConvertBitmap()

How does it work?

  1. Use PDFium to render a bitmap (for PDF files)
  2. Make the bitmap monochrome
  3. Convert the bitmap into a ^GF (Graphic Field) command
  4. Compress the command hexdecimal data to shrink the ZPL code in size
  5. Return the generated ZPL code
