This quick tutorial focuses on how to convert PNG to PowerPoint Slide in Java. It covers all the necessary information about the configuration, step-wise process, and a working sample code to write a PNG to PPTX converter in Java. The sample code exhibits the complete scenario and can be used in any of the Java configured operating systems like Windows, Linux, or macOS.

Steps to Convert PNG to PPTX in Java

1. Configure the application by installing Aspose.Slides for Java from the Maven repository
2. Instantiate the Presentation class object to add a default empty presentation
3. Access the first default slide in presentation slides collection
