  • Temporary License: Obtain a temporary license for extended access.
  • Purchase: Purchase a full license if you decide to integrate it into your production environment.

Basic Initialization and Setup

Initialize GroupDocs.Conversion in your .NET project as follows:

using GroupDocs.Conversion;
// Create an instance of the Converter class with the path to your XPS file
Converter converter = new Converter("YOUR_DOCUMENT_DIRECTORY/SAMPLE_XPS");

Implementation Guide

Feature 1: XPS to JPG Conversion

This section demonstrates converting an XPS document into a series of JPG images using GroupDocs.Conversion.

Overview

Converting from XPS to JPG is essential for sharing documents in universally supported formats. This feature guides you through configuring conversion options and executing the process.

Step-by-Step Implementation

1. Configure Output Directory Set up an output directory where your converted files will be stored:

string outputFolder = "YOUR_OUTPUT_DIRECTORY";

Define a template for naming output files, ensuring they are sequentially numbered:

string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.jpg");

2. Define Stream Function Create a function that generates file streams for each page of the converted document:

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

3. Perform Conversion Initialize the converter and set up image conversion options:

using (Converter converter = new Converter("YOUR_DOCUMENT_DIRECTORY/SAMPLE_XPS"))
{
    ImageConvertOptions options = new ImageConvertOptions { Format = ImageFileType.Jpg };
    // Convert the document using the defined stream function and options
    converter.Convert(getPageStream, options);
}

Explanation of Key Components

  • SavePageContext: Provides context about each page being converted.
  • ImageConvertOptions: Configures the output format (JPG in this case).
  • converter.Convert(): Executes the conversion using specified settings.

Feature 2: Output Directory Configuration

Configuring your output directory path is crucial for organizing and accessing your converted files efficiently.

Overview

This feature demonstrates setting up a method to define and retrieve the output directory’s path dynamically.

1. Define Method Implement a simple function that returns the path of your output directory:

string GetOutputDirectoryPath()
{
    return "YOUR_OUTPUT_DIRECTORY";
}

Practical Applications

Explore real-world scenarios where converting XPS to JPG can be beneficial:

  • Document Sharing: Easily share documents with colleagues or clients who prefer image formats.
  • Web Publishing: Prepare documents for web display by converting them into a series of images.
  • Archiving: Convert legacy XPS files to JPG for long-term storage in modern systems.

Performance Considerations

When working with GroupDocs.Conversion, consider these performance tips:

  • Optimize Resource Usage: Use streams efficiently and dispose of resources properly after conversion.
  • Memory Management: Ensure you’re managing memory by releasing unused objects to prevent leaks in .NET applications.

Conclusion

In this tutorial, we explored converting XPS files to JPG using GroupDocs.Conversion for .NET. You’ve learned how to set up your environment, implement the conversion feature, and apply it in practical scenarios. As next steps, consider exploring additional features of GroupDocs.Conversion or integrating these solutions into larger workflows.

FAQ Section
