Implementation Guide

Step 1: Load the Source DOT File

Load your DOT file using GroupDocs.Conversion:

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
class Program
{
    static void Main(string[] args)
    {
        string sampleDotFilePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample.dot");
        
        // Load the DOT file into the Converter.
        using (Converter converter = new Converter(sampleDotFilePath))
        {
            Console.WriteLine("DOT file loaded successfully.");
        }
    }
}

Step 2: Set Up Output Directory

Ensure your output directory exists to store the converted JPG files:

string outputFolder = Path.Combine("YOUR_OUTPUT_DIRECTORY", "ConvertedDocuments");
Directory.CreateDirectory(outputFolder);

Step 3: Define Conversion Options and Stream Function

Set up conversion options for the JPG format and define a function to handle each page’s stream:

// Template for naming converted files.
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg");

Func<SavePageContext, Stream> getPageStream = savePageContext =>
{
    // Create a FileStream for each converted page.
    return new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);
};

Step 4: Perform the Conversion

Execute the conversion process using the defined options:

using (Converter converter = new Converter(sampleDotFilePath))
{
    // Set JPG conversion options.
    ImageConvertOptions options = new ImageConvertOptions { Format = ImageFileType.Jpg };
    
    // Convert and save each page as a separate JPG file.
    converter.Convert(getPageStream, options);
}

Console.WriteLine("Conversion completed successfully.");

Troubleshooting Tips

  • Missing Files: Ensure the DOT file path is correct and accessible.
  • Permission Issues: Verify that your application has write permissions for the output directory.
