Dynamic Watermark Edit for DOC in Node.js via Java

GroupDocs.Watermark for Node.js via Java offers Node.js via Java developers a powerful API for editing watermarks across diverse DOC documents. Here’s a comprehensive guide to streamline your workflow:

Start the Process: Begin by providing your DOC file as an argument to the Watermarker class constructor. Depending on your requirements, the file can be sourced either as a stream or from a local disk location.
Pinpoint Watermarks: Use the SearchCriteria object to identify the watermarks in need of modification. This versatile tool enables targeted watermark selection based on specific properties.
Refine with Precision: Upon successful execution of the search, gain access to a collection of relevant watermarks. Enjoy granular control over each element, with the ability to update dimensions, page positioning, text content, color, image data, and more.
Seamless Persistence: Once watermark updates are complete, securely store the modified document. The API offers flexible storage options, allowing you to save to a local file path or as a stream object.
