Read-Only Recommended Properties in Java Slides

Introduction to Enabling Read-Only Recommended Properties in Java Slides

In this tutorial, we will explore how to enable Read-Only Recommended properties for PowerPoint presentations using Aspose.Slides for Java. Read-Only Recommended properties can be useful when you want to encourage users to view a presentation without making any changes. These properties suggest that the presentation should be opened in read-only mode. We will provide you with a step-by-step guide along with Java source code to achieve this.

Prerequisites

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

Step 1: Create a New PowerPoint Presentation

We’ll start by creating a new PowerPoint presentation using Aspose.Slides for Java. If you already have a presentation, you can skip this step.

String outPptxPath = "Your Output Directory" + "ReadOnlyRecommended.pptx";
Presentation pres = new Presentation();

In the code above, we’ve defined the path for the output PowerPoint file and created a new presentation object.

Step 2: Enable Read-Only Recommended Property

Now, let’s enable the Read-Only Recommended property for the presentation.

try
{
    pres.getProtectionManager().setReadOnlyRecommended(true);
    pres.save(outPptxPath, SaveFormat.Pptx);
}
finally
{
    if (pres != null) pres.dispose();
}

In this code snippet, we use the getProtectionManager().setReadOnlyRecommended(true) method to set the Read-Only Recommended property to true. This ensures that when someone opens the presentation, they will be prompted to open it in read-only mode.

Step 3: Save the Presentation

Finally, we save the presentation with the Read-Only Recommended property enabled.

Complete Source Code For Read-Only Recommended Properties in Java Slides

String outPptxPath = "Your Output Directory" + "ReadOnlyRecommended.pptx";
Presentation pres = new Presentation();
try
{
	pres.getProtectionManager().setReadOnlyRecommended(true);
	pres.save(outPptxPath, SaveFormat.Pptx);
}
finally
{
	if (pres != null) pres.dispose();
}

Conclusion

In this tutorial, you have learned how to enable the Read-Only Recommended property for a PowerPoint presentation using Aspose.Slides for Java. This feature can be helpful when you want to restrict editing and encourage viewers to use the presentation in read-only mode. You can further enhance security by setting a password for the presentation.
