Load Format Enumeration in Java Slides

Introduction to Loading Presentation Format in Java Slides

In this tutorial, we will explore how to determine the format of a PowerPoint presentation using the Aspose.Slides for Java API. We’ll specifically focus on loading a presentation and checking its format using the LoadFormat enumeration. This will help you identify whether the presentation is in an older format, such as PowerPoint 95, or a more recent format.

Prerequisites

Before we begin, make sure you have the Aspose.Slides for Java library installed and set up in your Java project. You can download it from the Aspose website and follow the installation instructions.

Step 1: Import Required Classes

To get started, you need to import the necessary classes from the Aspose.Slides library. These classes will allow us to work with presentations and check their formats.

import com.aspose.slides.LoadFormat;
import com.aspose.slides.PresentationFactory;

Step 2: Load the Presentation

In this step, we will load the PowerPoint presentation file that you want to check for its format. Replace "Your Document Directory" with the actual path to your presentation file.

String dataDir = "Your Document Directory";
boolean isOldFormat = PresentationFactory.getInstance().getPresentationInfo(dataDir + "presentation.ppt").getLoadFormat() == LoadFormat.Ppt95;

In the code above, we use PresentationFactory.getInstance().getPresentationInfo() to obtain information about the presentation, including its format. We then compare the format with LoadFormat.Ppt95 to check if it’s an older PowerPoint 95 format.
