Java (481)
The slide master in PowerPoint preserves some fixed styles, such as background image, title and theme color, which can be inherited by other slides. This article demonstrates how to customize the slide masters in a PowerPoint file and apply them to different slides using Spire.Presentation for Java.

When a PowerPoint presentation is converted to PDF, its document layout and formatting are fixed. Recipients can view the converted document without having Microsoft PowerPoint to be installed, but they can not modify it easily. In this article, we will demonstrate how to convert PowerPoint presentations to PDF in Java using Spire.Presentation for Java library.
- Convert a Whole PowerPoint Presentation to PDF
- Convert Specific Slide of a PowerPoint Presentation to PDF
Install Spire.Presentation for Java
First of all, you're required to add the Spire.Presentation.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.
<repositories>
<repository>
<id>com.e-iceblue</id>
<name>e-iceblue</name>
<url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.presentation</artifactId>
<version>11.1.1</version>
</dependency>
</dependencies>
Convert a Whole PowerPoint Presentation to PDF in Java
The following steps show you how to convert a whole PowerPoint presentation to PDF:
- Initialize an instance of Presentation class.
- Load the PowerPoint presentation using Presentation.loadFromFile() method.
- Save it to PDF using Presentation.saveToFile(filePath, FileFormat.PDF) method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;
public class ConvertPowerPointToPDF {
public static void main(String []args) throws Exception {
//Create a Presentation instance
Presentation ppt = new Presentation();
//Load a PowerPoint presentation
ppt.loadFromFile("Sample.pptx");
//Save it as PDF
ppt.saveToFile("ToPdf1.pdf", FileFormat.PDF);
}
}
Convert Specific Slide of a PowerPoint Presentation to PDF in Java
The following steps show you how to convert a specific slide of a PowerPoint presentation to PDF:
- Initialize an instance of Presentation class.
- Load the PowerPoint presentation using Presentation.loadFromFile() method.
- Get the desired slide by its index using Presentation.getSlides().get(slideIndex) method.
- Save it to PDF using ISlide.saveToFile(filePath, FileFormat.PDF) method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;
public class ConvertSlidesToPDF {
public static void main(String []args) throws Exception {
//Create a Presentation instance
Presentation ppt = new Presentation();
//Load a PowerPoint presentation
ppt.loadFromFile("Sample.pptx");
//Get the second slide
ISlide slide= ppt.getSlides().get(1);
//Save the slide to PDF
slide.saveToFile("ToPdf2.pdf", FileFormat.PDF);
}
}
