Convert Document to PDF

Overview

In this section, we will convert a document from any supported format (e.g., DOCX) into a PDF file.

1. Initialize the Viewer with Your Document

Start by creating an instance of Viewer and providing it the path to your document:

try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX")) {
    // Further processing will be done here.
}

2. Set Up PDF View Options

Next, configure the PdfViewOptions using a custom file stream factory. This allows you to control how the output is managed:

MemoryFileStreamFactory streamFactory = new MemoryFileStreamFactory();
PdfViewOptions options = new PdfViewOptions(streamFactory);

3. Render the Document to PDF Format

Use the view() method on your Viewer instance to perform the conversion:

viewer.view(options);

4. Obtain and Use the Resulting PDF Stream

Finally, extract the resulting PDF as an input stream for further use or storage:

InputStream pdfStream = streamFactory.getStream();
pdfStream.close(); // Always remember to close streams after usage.
