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?

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