Quick Start

using TrinePDF.Core;

// Create a new PDF document (A4, portrait, millimeters)
using var doc = new PdfDocument(PageOrientation.Portrait, PdfUnit.Millimeters, PageSize.A4);

// Set document metadata
doc.Title = "My First PDF";
doc.Author = "Your Name";

// Configure margins
doc.SetMargins(15, 15, 15);

// Add a page
doc.AddPage();

// Set the font and write text
doc.SetFont("Helvetica", FontStyle.Bold, 16);
doc.Cell(0, 10, "Hello from TrinePDF!", newLine: true, align: TextAlign.Center);

doc.SetFont("Helvetica", FontStyle.None, 12);
doc.Cell(0, 8, "This PDF was generated entirely in managed C#.");

// Save to file
doc.Save("output.pdf");

Installation

Install the core library from NuGet:

dotnet add package TrinePDF

For lightweight inline HTML rendering:

dotnet add package TrinePDF.Html.Inline

For full HTML-to-PDF support (browser-based):

dotnet add package TrinePDF.Html

Requirements

  • .NET 10 or later
  • SkiaSharp, HarfBuzzSharp, and ZXing.Net (pulled automatically via NuGet)
  • On Linux, also reference SkiaSharp.NativeAssets.Linux (or .NoDependencies for containers) and HarfBuzzSharp.NativeAssets.Linux; neither base package ships a Linux native binary
  • For inline HTML rendering: AngleSharp (included in the TrinePDF.Html.Inline package)
  • For full HTML-to-PDF: PuppeteerSharp (included in the TrinePDF.Html package; downloads Chromium on first use)
