Implementation Guide

Now, let’s break down the merging process into manageable steps using specific features provided by GroupDocs.Merger for Java.

Load a Source VSDX File

Overview: Start by loading the initial Visio file that you want to use as your base document in the merge operation.

Step 1: Import Required Classes

import com.groupdocs.merger.Merger;

Step 2: Define and Load Document Path

Specify the path of your source VSDX file:

String documentPath = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_VSDX";
Merger merger = new Merger(documentPath);

Ensure documentPath points to a valid .vsdx file. This step initializes the merge process with your primary document.

Add Another VSDX File for Merging

Overview: Enhance your initial document by adding another Visio file into the merging operation.

Step 1: Define Additional Document Path

Set the path to the additional file you wish to merge:

String additionalDocumentPath = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_VSDX_2";

Step 2: Merge Files Using join()

Use the join method to combine your documents:

Merger merger = new Merger(documentPath); // Reuse 'documentPath' from earlier.
merger.join(additionalDocumentPath);

The join function takes another file path as input and appends it to the original document.

Save the Merged VSDX File

Overview: Once your files are merged, save the result into a single output Visio file.

Step 1: Define Output Path

Set up where you want to store the final merged document:

String outputFolder = "YOUR_OUTPUT_DIRECTORY";
String outputFile = new File(outputFolder, "merged.vsdx").getPath();

Step 2: Save Merged Document

Invoke the save method to write your merged file:

Merger merger = new Merger(documentPath);
merger.join(additionalDocumentPath); // Ensure both files are added.
merger.save(outputFile);

The merged document will now be saved at the specified location.
