Basic Initialization

Here’s how to set up your project with GroupDocs.Conversion:

using System;
using GroupDocs.Conversion;

namespace EmzToJpgConverter
{
    class Program
    {
        static void Main(string[] args)
        {
            // Set your document directory path here
            string sourceFilePath = @"YOUR_DOCUMENT_DIRECTORY/sample.emz";

            // Load the EMZ file
            using (var converter = new Converter(sourceFilePath))
            {
                Console.WriteLine("EMZ file loaded successfully.");
                // Further conversion steps will be discussed below.
            }
        }
    }
}

Implementation Guide

We’ll break down the implementation into several logical sections based on specific features.

Load Source EMZ File

This feature demonstrates how to load an .emz file using GroupDocs.Conversion. This is your starting point for any conversion process.

Overview

Loading a source file correctly ensures that subsequent operations are performed on valid data, which is crucial for successful conversions.

Implementation Steps

  1. Initialize the Converter Class
    • Use the Converter class to load your EMZ file.
  2. Set Your Document Directory Path
    • Ensure you specify the correct path where your .emz files are stored.
using System;
using GroupDocs.Conversion;

string sourceFilePath = @"YOUR_DOCUMENT_DIRECTORY/sample.emz";

// Load the EMZ file
using (Converter converter = new Converter(sourceFilePath))
{
    Console.WriteLine("EMZ file loaded successfully.");
}

Configure Convert Options for JPG Format

This feature sets up conversion options specific to transforming an image into a JPEG format.

Overview

Configuring convert options allows you to tailor your output according to your needs, such as specifying the output format and other settings.

Implementation Steps

  1. Initialize ImageConvertOptions
    • Set the desired output format using ImageConvertOptions.
using System;
using GroupDocs.Conversion.Options.Convert;

class ImageConvertOptionsExample
{
    public static void ConfigureJpgConversion()
    {
        ImageConvertOptions options = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Jpg };
        Console.WriteLine("JPEG conversion options configured.");
    }
}

Convert EMZ to JPG

This feature performs the actual conversion process from an EMZ file to a JPEG image.

Overview

The conversion leverages previously set up configurations and streams the output to your desired directory.

Implementation Steps

  1. Set Output Directory Path
    • Define where you want your converted files to be stored.
  2. Implement Conversion Logic
    • Use Convert method with a stream function and options.
using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

string templatePath = @"YOUR_OUTPUT_DIRECTORY/converted-page-{0}.jpg";

Func<SavePageContext, Stream> getPageStream = savePageContext =>
    new FileStream(string.Format(templatePath, savePageContext.Page), FileMode.Create);

class EmzToJpgConversionExample
{
    public static void ConvertEmzToJpg(Converter converter, ImageConvertOptions options)
    {
        converter.Convert(getPageStream, options);
        Console.WriteLine("EMZ file converted to JPG successfully.");
    }
}

Practical Applications

Real-World Use Cases

  1. Document Management Systems: Automatically convert and store document images in a uniform format for easier access.
  2. Web Applications: Serve images efficiently by converting them to web-friendly formats like JPEG.
  3. Archiving Solutions: Preserve documents by converting proprietary formats to more universally accessible ones.
