Implementation Guide

Loading and Converting EMF to PDF

Overview

This section will guide you through loading an EMF file and converting it into a PDF document using GroupDocs.Conversion for .NET.

Step 1: Load the EMF File

// Ensure your file path is correct and accessible.
string emfFilePath = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "yourfile.emf");
Converter converter = new Converter(emfFilePath);

Why: Loading the file first ensures that all subsequent operations have access to a valid document.

Step 2: Set Conversion Options

PdfConvertOptions options = new PdfConvertOptions();

Why: Setting up these options allows customization of the output PDF, such as page size and margins.

Step 3: Convert EMF to PDF

string outputFilePath = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "output.pdf");
converter.Convert(outputFilePath, options);

Why: This step performs the actual conversion from EMF to PDF using specified settings.
