PDFtoZPL

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

This .NET library is built on top of

PDFium (native PDF renderer)
SkiaSharp (cross-platform 2D graphics API)

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?

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