This article will demonstrate how to add a variety of shapes to a PowerPoint slide and how to fill the shapes with a solid color, a picture, a pattern or a gradient using Java.

Tools: ● Free Spire.Presentation for Java ● IntelliJ IDEA

Installation (2 Methods) ● Download the free Java API and unzip it. Then add the Spire.Presentation.jar file to your project as dependency.

● You can also add the jar dependency to your maven project by adding the following configurations to the pom.xml.
