pdfOffice + iText Core Annotations Example

Background:

With the addition of pdfOffice to the iText 7 Suite portfolio comes a wide range of potential synergies and new frontiers for your company's document workflow, thanks to its capabilities for accurate conversion of MS Office documents to PDF.

In this example, we will demonstrate how a potential client may utilize pdfOffice + iText Core in order to convert a .docx file into a PDF, then apply a comment as a PDF annotation. This is an especially relevant use-case for organizations dealing with contract work, invoicing, and potentially receipts.

Code Snippet:

In the following code snippet, we take the first three paragraphs from Lewis Carroll's classic novel Alice's Adventures in Wonderland (commonly known as simply Alice in Wonderland) in a .docx as input. After using pdfOffice to convert our Microsoft Word document into a PDF, we then utilize iText Core to apply a simple text annotation onto our favorite section of the reading.
