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.

Great article! So I had a look at the other products offered by Spice and it looks like the cover a lot, including PDF generation, bar code generation and much more. Do you know how the licensing works and what is free?
They have a list of products like Spire.Doc, Spire.PDF, Spire.XLS, Spire.Presentation that are used to manipulate documents in different formats on .NET or Java platforms. Only the commercial version needs to apply a license to remove the evaluation message on the generated documents, while the free version doesn't need that and there's no evaluation message, but free veison has certain page limitations.
