Precise PDF Page Control Using C# and .NET
PDF-A Factor (also known as ZUGFeRD) is an electronic invoice format that combines both a human-readable PDF document and structured XML data that allows you to automate invoice processing. This format complies with the European standard EN 16931 (syntax CII D16B) and supports various versions of PDF/A (for example, PDF/A-3), which ensures long-term storage and accessibility of documents. In this article, we will look at how to use the SautinSoft.PDF.Net library for converting files to FacturX PDF format using C# and .Net.
Step-by-step guide:
- Add SautinSoft.PDF from NuGet.
- Load a PDF document.
- Create PDF save options like the FacturX Zugferd.
- Select the desired PDF/A version.
- Save a PDF document.
