A .NET library to convert [PDF files](https://en.wikipedia.org/wiki/PDF) (and bitmaps) into [Zebra Programming Language commands](https://en.wikipedia.org/wiki/Zebra_(programming_language)).

This .NET library is built on top of

* [PDFium](https://pdfium.googlesource.com/pdfium/) (native PDF renderer)

* [SkiaSharp](https://github.com/mono/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
