Update Watermarks in POWERPOINT via Node.js via Java

GroupDocs.Watermark for Node.js via Java equips Node.js via Java developers with a robust API for programmatically updating watermarks within various POWERPOINT documents. This guide outlines the process:

Start the process by supplying your POWERPOINT file as an argument to the Watermarker class constructor. Depending no your demands the file can be provided as either a stream or a reference to a local disk location.
Subsequently, leverage the SearchCriteria object to identify the specific watermarks requiring modification. This object enables the pinpointing of watermarks based on the desired properties.
Upon successful execution of the search, you’ll receive a collection of relevant watermarks. These watermarks offer granular control, allowing you to update properties such as dimensions, page positioning, text content, color scheme, image data, and more.
Following the completion of watermark updates, persist the modified document. The API facilitates storage using either a local file path or a stream object.

Copy


// Update POWERPOINT text watermark

// Provide Watermarker instance for POWERPOINT file
const watermarker = new groupdocs.watermark.Watermarker("input.pptx");

// Use TextSearchCriteria to find text watermarks
const searchCriteria = 
    new groupdocs.watermark.TextSearchCriteria("test", false);
const watermarks = watermarker.search(searchCriteria);

// Update text watermark
for (const watermark of watermarks.getInnerList().toArray())
{
    watermark.setText("passed");
}

// Enjoy the result
watermarker.save("output.pptx");
