Implementation Guide

Now, let’s dive into implementing responsive HTML rendering using GroupDocs.Viewer.

Render Document to Responsive HTML

This feature allows you to convert documents into responsive HTML pages. Here are the implementation steps:

Step 1: Import Required Classes

Start by importing necessary classes from the GroupDocs library:

import com.groupdocs.viewer.Viewer;
import com.groupdocs.viewer.options.HtmlViewOptions;

Step 2: Define Document Paths

Set up your input and output paths for document rendering:

String inputDocumentPath = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX";
String outputDirectoryPath = "YOUR_OUTPUT_DIRECTORY";

Replace these placeholders with actual paths in your project.

Step 3: Initialize Viewer Object

Create a Viewer object to handle the file processing. Use a try-with-resources statement for efficient resource management:

try (Viewer viewer = new Viewer(inputDocumentPath)) {
    // Proceed with rendering options setup
}

Step 4: Configure HTML View Options

Configure your HTML view settings, including enabling responsive rendering:

String pageFilePathFormat = outputDirectoryPath + "/page_{0}.html";
HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources(pageFilePathFormat);
viewOptions.setRenderResponsive(true); // Enable responsive rendering

Step 5: Render the Document

Execute the document rendering process:

viewer.view(viewOptions);

This will generate HTML pages that adapt to various screen sizes.

Troubleshooting Tips

  • Common Issue: If your output isn’t responsive, ensure setRenderResponsive(true) is called.
  • Missing Files: Verify paths are correct and directories exist.

Practical Applications

Responsive HTML rendering with GroupDocs.Viewer opens up a plethora of use cases:

  1. Online Document Portals: Display user-uploaded documents in web applications seamlessly across devices.
