Implementation Guide

Load Source ODT File

Loading an Open Document Template file into the merger object is the first step before merging additional documents.

Step-by-Step Implementation:

  1. Specify the File Path: Define the path to your source ODT file.

    string sourceOttFilePath = "YOUR_DOCUMENT_DIRECTORY\source.odt"; // Replace with your actual path

  2. Load the Source ODT File: Use the Merger class to load the file.

    using (var merger = new Merger(sourceOttFilePath))
{
    // The source ODT file is now loaded for further operations.
}

Add Another ODT File to Merge

To merge additional ODT files, follow these steps:

Step-by-Step Implementation:

  1. Specify Additional File Path: Set the path for the additional ODT file.

    string additionalOttFilePath = "YOUR_DOCUMENT_DIRECTORY\additional.odt"; // Replace with your actual path

  2. Add the File to Merge: Use the Join method to add the new document.

    using (var merger = new Merger(sourceOttFilePath))
{
    merger.Join(additionalOttFilePath); // Add an additional ODT file for merging.
}

Merge ODT Files and Save Result

Finally, save your merged documents as a single output file.

Step-by-Step Implementation:

  1. Define Output Path: Determine where to save the merged file.

    string outputFolder = "YOUR_OUTPUT_DIRECTORY"; // Placeholder for the output directory path
string outputFile = Path.Combine(outputFolder, "merged.odt");

  2. Save Merged Document: Use the Save method to write the result.

    using (var merger = new Merger(sourceOttFilePath))
{
    merger.Join(additionalOttFilePath); // Add an additional ODT file for merging.
    merger.Save(outputFile); // Save the merged output as a single ODT file.
}

Practical Applications

Here are some real-world scenarios where merging ODT files can be beneficial:

  1. Project Documentation: Combine multiple project templates into one comprehensive master document.
  2. Report Generation: Merge various sections of reports for a unified presentation.
  3. Template Consolidation: Create a single template from different departmental versions for uniformity.
