⚡ ShreePdf Engine

Radiant Aesthetics. Intelligent PDF Engineering for the AI Era.

A next-generation C# PDF document generation library featuring universal Markdown ingestion, anti-orphan page budgeting, AI/RAG dual-stream metadata embedding, out-of-the-box themes, and SkiaSharp vector rendering.

🚀 4 Core Innovations of ShreePdf

1. 🤖 Universal Markdown & HTML Ingestion Engine

Render LLM outputs (GPT-4o, Claude, Gemini) and HTML/Razor views directly into PDF document AST without HTML wrappers or headless browser overhead.

var doc = Document.FromMarkdown(llmMarkdownText, ThemePresets.GlassmorphicDark);
doc.AddHtml("<h1 style='color:#a855f7;'>Razor & HTML View Support</h1>");

2. 📐 Anti-Orphan Smart Auto-Fit Budgeter

Eliminates 1.05-page documents spilling 1–3 orphan lines onto a blank second page. It dynamically micro-adjusts typography spacing, line heights, and padding by 5–12% to fit content cleanly on 1 page.

doc.EnableAutoFit(true);

3. 🧠 AI / RAG Dual-Stream Metadata Embedder

Embeds a structured JSON AST directly inside the PDF binary metadata stream (RagMetadataManager). Downstream AI agents and vector databases extract data with 100% loss-free accuracy without OCR.

// Extract loss-free AST JSON directly from PDF bytes
string astJson = RagMetadataManager.ExtractAstJsonFromPdfBytes(pdfBytes);

4. 🎨 Out-of-the-Box Modern Theme Engine

Eliminates ugly default PDFs by bundling modern themes (ThemePresets.SaaSAnalytics, ExecutiveMinimal, GlassmorphicDark).

doc.WithTheme(ThemePresets.SaaSAnalytics);

🧪 Quality Assurance & Test Coverage Dashboard

ShreePdf features an extensive unit test suite verifying layout math, color models, HTML tag parsing, and cryptographic security.

💻 Quickstart

using ShreePdf.Fluent;
using ShreePdf.Licensing;
using ShreePdf.Metadata;
using ShreePdf.Web;

// 1. Set License
LicenseManager.SetLicenseKey("SHREE-ENTERPRISE-...");

// 2. Ingest Markdown, Add HTML & Apply Dark Theme
string llmText = "# Quarterly Review\n> Loss-free RAG indexing enabled.\n- Fast SkiaSharp rendering";
var doc = Document.FromMarkdown(llmText, ThemePresets.GlassmorphicDark)
    .AddHtml("<p style='color:#10b981; font-weight:bold;'>ASP.NET Core Razor Middleware Ready</p>")
    .EnableAutoFit(true)
    .EnableRagMetadata(true);

// 3. Export PDF & Extract RAG JSON
byte[] pdfBytes = doc.GenerateBytes();
string ragJson = RagMetadataManager.ExtractAstJsonFromPdfBytes(pdfBytes);
doc.Save("Report.pdf");
