Implementation Guide

Let’s break down the merging process into clear steps to help you efficiently merge XPS files.

Merging Multiple XPS Files

This feature allows you to combine several XPS documents into a single file, simplifying document management and distribution.

Step 1: Define File Paths

Firstly, specify paths for your source XPS files. Replace YOUR_DOCUMENT_DIRECTORY with the actual directory where your files are stored:

const string SAMPLE_XPS = "YOUR_DOCUMENT_DIRECTORY/sample1.xps";
const string SAMPLE_XPS_2 = "YOUR_DOCUMENT_DIRECTORY/sample2.xps";
const string OUTPUT_DIRECTORY = "YOUR_OUTPUT_DIRECTORY";

Step 2: Create Output Directory

Ensure the output directory exists or create it if necessary:

string outputFolder = OUTPUT_DIRECTORY;
if (!Directory.Exists(outputFolder))
    Directory.CreateDirectory(outputFolder);

Step 3: Load and Merge XPS Files

Load your source file using GroupDocs.Merger, add additional files to merge, and save the result:

void MergeXpsFiles()
{
    string outputFile = Path.Combine(outputFolder, "merged.xps");
    
    // Initialize Merger with first XPS file
    using (var merger = new Merger(SAMPLE_XPS))
    {
        // Add another XPS file to merge
        merger.Join(SAMPLE_XPS_2);
        
        // Save the merged result into a single output XPS file
        merger.Save(outputFile);
    }
}

Explanation of Code

  • Using Statement: Ensures that resources are disposed of properly after use.
  • Merger Class: Handles loading and combining files.
  • Join Method: Adds another document to the merge operation.
  • Save Method: Writes the combined output to a specified path.

Practical Applications

Merging XPS files can be useful in several real-world scenarios:

  1. Publishing: Combine different sections of a publication into one file for easier distribution.
  2. Document Management Systems: Integrate with systems that require consolidated document formats.
  3. Workflow Automation: Streamline processes where documents from various sources need to be unified.

Performance Considerations

To ensure optimal performance when using GroupDocs.Merger:

  • Monitor memory usage, especially with large files.
  • Dispose of objects promptly to free up resources.
  • Follow best practices for .NET memory management to prevent leaks and inefficiencies.

Conclusion

By following this guide, you have learned how to efficiently merge multiple XPS files using GroupDocs.Merger for .NET. This skill can greatly enhance your document handling capabilities in various professional scenarios.
