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

class Program
{
    static void Main()
    {
        // Define paths for the document and output directories
        string documentDirectory = "YOUR_DOCUMENT_DIRECTORY"; // Replace with your actual path
        string outputDirectory = "YOUR_OUTPUT_DIRECTORY"; // Replace with your actual path

        // Construct full paths for input EMF file and output SVG file
        string inputFile = Path.Combine(documentDirectory, "sample.emf"); // Ensure 'sample.emf' exists in your directory
        string outputFile = Path.Combine(outputDirectory, "emf-converted-to.svg");

        // Load the source EMF file using GroupDocs.Conversion.Converter
        using (var converter = new Converter(inputFile))
        {
            // Set conversion options for SVG format
            var convertOptions = new PageDescriptionLanguageConvertOptions
            {
                Format = GroupDocs.Conversion.FileTypes.PageDescriptionLanguageFileType.Svg
            };

            // Perform the conversion from EMF to SVG and save the output file
            converter.Convert(outputFile, convertOptions);
        }
    }
}

Implementation Guide

Load and Convert EMF File to SVG

Overview: This feature allows seamless loading of an EMF file and its conversion into SVG format using GroupDocs.Conversion for .NET.

Step 1: Define Paths

Define paths where your source EMF files are located and where you want the converted SVGs saved:

string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";

Step 2: Construct File Paths

Create full file paths for both input and output files. Ensure your source file exists in the specified directory to prevent errors:

string inputFile = Path.Combine(documentDirectory, "sample.emf");
string outputFile = Path.Combine(outputDirectory, "emf-converted-to.svg");

Step 3: Initialize Converter

Use GroupDocs.Conversion’s Converter class to load your EMF file. This step prepares the file for conversion:

using (var converter = new Converter(inputFile))
{
    // Conversion logic will be added here.
}

Step 4: Set Conversion Options

Define output format and other necessary options using PageDescriptionLanguageConvertOptions:

var convertOptions = new PageDescriptionLanguageConvertOptions
{
    Format = GroupDocs.Conversion.FileTypes.PageDescriptionLanguageFileType.Svg
};

Step 5: Perform Conversion

Execute the conversion by calling the Convert method with your output file path and conversion options:

converter.Convert(outputFile, convertOptions);

Troubleshooting Tips

• File Not Found: Verify that the input EMF file exists in the specified directory.
• Permission Issues: Check write permissions for the output directory.
• Library Version Mismatch: Ensure you’re using a compatible version of GroupDocs.Conversion.

Practical Applications

Converting EMF to SVG is beneficial in scenarios like:

1. Web Design: Use SVGs for scalable graphics that maintain quality at any size.
2. Architectural Plans: Convert detailed drawings from EMF to SVG for easy online sharing and editing.
3. Graphic Design: Enhance workflows using vector formats like SVG, supporting intricate designs without detail loss.

Performance Considerations

When converting files in .NET:

• Optimize Resource Usage: Monitor memory usage when handling large files.
• Best Practices for Memory Management: Dispose of objects properly and use using statements to manage resources efficiently.

Conclusion

By following this guide, you’ve learned how to effectively convert EMF files to SVG format using GroupDocs.Conversion for .NET. This skill enhances your development capabilities and opens opportunities in domains requiring high-quality vector graphics.
