Implementation Guide

In this section, we’ll guide you through the process of rendering presentations that include notes.

Feature: Render a Presentation with Notes

This feature focuses on displaying your presentation files along with their embedded notes using GroupDocs.Viewer for Java. This is particularly useful when notes need to be reviewed alongside slide content.

Step 1: Define Output Directory and File Format

Begin by setting up the output directory where the rendered HTML files will be saved:

import java.nio.file.Path;
import java.nio.file.Paths;

Path YOUR_DOCUMENT_DIRECTORY = Paths.get("YOUR_DOCUMENT_DIRECTORY");
Path pageFilePathFormat = YOUR_OUTPUT_DIRECTORY.resolve("page_{0}.html");

Step 2: Configure View Options

Next, create view options for rendering the presentation with embedded resources:

import com.groupdocs.viewer.options.HtmlViewOptions;

HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources(pageFilePathFormat);
viewOptions.setRenderNotes(true); // Enable note rendering

Explanation: forEmbeddedResources allows you to render documents into HTML format with all necessary resources embedded. Setting setRenderNotes(true) ensures that notes are included in the rendered output.

Step 3: Load and Render Document

Finally, load your presentation document and render it using the specified view options:

try (Viewer viewer = new Viewer(YOUR_DOCUMENT_DIRECTORY.resolve("TestFiles.PPTX_WITH_NOTES"))) {
    // Render document to HTML with notes included
    viewer.view(viewOptions);
}

Troubleshooting Tip: Ensure that your file paths are correctly set and accessible, as incorrect paths may lead to FileNotFoundException.
