Feature 1: Setting Up Load Options for Font Substitution

Overview

Specify default fonts and substitutes when loading a Word document to ensure consistent typography in your output PDF.

Step 1: Define Load Options

using System;
using System.Collections.Generic;
using GroupDocs.Conversion.Contracts;
using GroupDocs.Conversion.Options.Load;

// Create load options with default and substitute fonts
Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new WordProcessingLoadOptions
{
    DefaultFont = "Helvetica", // Default font used when a specific one is unavailable
    FontSubstitutes = new List<FontSubstitute>
    {
        FontSubstitute.Create("Tahoma", "Arial"), // Replace Tahoma with Arial
        FontSubstitute.Create("Times New Roman", "Arial") // Replace Times New Roman with Arial
    }
};
  • Parameters: LoadContext and LoadOptions configure how documents are loaded.
  • Purpose: Ensures fallback to specified substitutes if specific fonts aren’t available.

Troubleshooting Tips

  • Ensure font paths are correctly set in your environment.
  • Validate that substitute fonts are installed on the conversion system.

Feature 2: Converting a Word Processing Document to PDF with Advanced Options

Overview

This feature demonstrates converting a Word document into a PDF, applying advanced load options for optimal results.

Step 1: Set Up Conversion Paths

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

// Define the output directory and file paths using placeholders
string outputFolder = @"C:\Output"; // Update with your actual path
string outputFile = Path.Combine(outputFolder, "converted.pdf");

// Initialize a Converter instance with specified load options
using (Converter converter = new Converter(@"C:\Documents\SAMPLE_DOCX_WITH_TRACKED_CHANGES", getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert(outputFile, options); // Perform the conversion
}
