Add a Text Watermark

Introduction

Using Aspose.Slides Cloud API, you have the capability to incorporate a text watermark into your slides within a PowerPoint presentation to serve a multitude of purposes. These purposes may include asserting authorship, developing a distinctive corporate presentation style, or designating the confidential nature of information. The watermark, in most cases, is a composition of either text or an image strategically positioned either in the background or foreground of the slide, and often has low transparency.

The following methods are for adding text watermarks to your presentation slides. You can specify many options for a watermark such as font height, font name, font color, text rotation, 3D effects, and many more.

The watermark shapes added to PowerPoint presentations are automatically named “watermark”.
