Highlight Text in PowerPoint in Java
The following are the steps to highlight specific text in a PowerPoint document:
- Initialize an instance of Presentation class.
- Load a PowerPoint presentation using Presentation.loadFromFile() method.
- Loop through the slides in the presentation and the shapes on each slide.
- Check if the current shape is of IAutoShape type.
- If the result is true, typecast it to IAutoShape.
- Initialize an instance of TextHighLightingOptions class, and set the text highlighting options such as whole words only and case sensitive using TextHighLightingOptions.setWholeWordsOnly() and TextHighLightingOptions.setCaseSensitive() methods.
- Highlight a specific text in the shape using IAutoShape.getTextFrame().highLightText() method.
- Save the result file using Presentation.saveToFile() method.
- Java
import com.spire.presentation.*;
import java.awt.*;
public class HighlightTextInPPT {
public static void main(String []args) throws Exception {
//Create an instance of Presentation class
Presentation presentation = new Presentation();
//Load a PowerPoint file
presentation.loadFromFile("Input.pptx");
//Loop through all slides
for (int i = 0; i < presentation.getSlides().getCount(); i++)
{
//Get the current slide
ISlide slide = presentation.getSlides().get(i);
//Loop through the shapes on the slide
for (int j = 0; j < slide.getShapes().getCount(); j++)
{
//Check if the current shape is of IAutoShape type
if (slide.getShapes().get(j) instanceof IAutoShape)
{
//Typecast the shape to IAutoShape
IAutoShape shape = (IAutoShape)slide.getShapes().get(j);
//Create an instance of TextHighLightingOptions class
TextHighLightingOptions options = new TextHighLightingOptions();
//Set text highlighting options
options.setCaseSensitive(true);
options.setWholeWordsOnly(true);
//Highlight specific text within the shape with color
shape.getTextFrame().highLightText("Spire", Color.YELLOW, options);
}
}
}
//Save the result file
presentation.saveToFile("HighlightText.pptx", FileFormat.PPTX_2013);
}
}

Java: Set, Retrieve, or Delete Document Properties in PowerPoint
2023-08-10 07:54:00 Written by KoohjiDocument properties of PowerPoint presentations hold immense value in managing and organizing presentations. The information in properties, including title, author, keywords, etc., provides a concise summary, aids in categorization and searchability, and contributes to maintaining a comprehensive presentation history. However, some useless document properties need to be deleted to prevent them from affecting document management. This article is going to show how to add, retrieve, or delete document properties in PowerPoint presentations using Spire.Presentation for Java.
- Add Document Properties to a PowerPoint Presentation
- Retrieve Document Properties from a PowerPoint Presentation
- Delete Document Properties of a PowerPoint Presentation
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.

Add Document Properties to a PowerPoint Presentation
Spire.Presentation for Java provides a set of methods under IDocumentProperty class to enable users to set and retrieve document properties of a presentation after getting the properties using the Presentation.getDocumentProperty() method. The detailed steps for adding document properties to a PowerPoint presentation are as follows:
- Create an object of Presentation class.
- Load a presentation file using Presentation.loadFromFile() method.
- Get the document properties of the presentation using Presentation.getDocumentProperty() method.
- Set the document properties using methods under IDocumentProperty class.
- Save the presentation using Presentation.saveToFile() method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.IDocumentProperty;
import com.spire.presentation.Presentation;
public class addPresentationProperties {
public static void main(String[] args) throws Exception {
//Create an object of Presentation class
Presentation presentation = new Presentation();
//Load a PowerPoint presentation
presentation.loadFromFile("Sample.pptx");
//Get the properties of the presentation and add items
IDocumentProperty property = presentation.getDocumentProperty();
property.setTitle("Annual Business Analysis Report");
property.setSubject("Business Analysis");
property.setAuthor("Taylor");
property.setManager("John");
property.setCompany("E-iceblue");
property.setCategory("Report");
property.setKeywords("Operating Analysis; Quarterly Operating Data; Growth");
property.setComments("The report has been revised and finalized and does not require further consultation.");
//Save the presentation file
presentation.saveToFile("AddProperties.pptx", FileFormat.AUTO);
presentation.dispose();
}
}
Retrieve Document Properties from a PowerPoint Presentation
The detailed steps for retrieving document properties from a PowerPoint presentation are as follows:
- Create an object of Presentation class.
- Load a presentation file using Presentation.loadFromFile() method.
- Get the properties of the presentation using Presentation.getDocumentProperty() method.
- Retrieve property information using methods under IDocumentProperty class and write it to a text file.
- Java
import com.spire.presentation.IDocumentProperty;
import com.spire.presentation.Presentation;
import java.io.FileWriter;
public class retrievePresentationProperties {
public static void main(String[] args) throws Exception {
//Create an object of Presentation class
Presentation presentation = new Presentation();
//Load a presentation file
presentation.loadFromFile("AddProperties.pptx");
//Get the properties of the presentation
IDocumentProperty property = presentation.getDocumentProperty();
//Get the properties and write them to a text file
String properties = "Title: " + property.getTitle() + "\r\n"
+ "Subject: " + property.getSubject() + "\r\n"
+ "Author: " + property.getAuthor() + "\r\n"
+ "Manager: " + property.getManager() + "\r\n"
+ "Company: " + property.getCompany() + "\r\n"
+ "Category: " + property.getCategory() + "\r\n"
+ "Keywords: " + property.getKeywords() + "\r\n"
+ "Comments: " + property.getComments();
FileWriter presentationProperties = new FileWriter("PresentationProperties.txt");
presentationProperties.write(properties);
presentationProperties.close();
}
}
Delete Document Properties of a PowerPoint Presentation
Removing document properties from a presentation is similar to adding properties. Just set the property data to null and the document properties can be removed. The details are as follows:
- Create an object of Presentation class.
- Load a presentation file using Presentation.loadFromFile() method.
- Get the document properties of the presentation using Presentation.getDocumentProperty() method.
- Set the document properties to null using methods under IDocumentProperty class.
- Save the presentation using Presentation.saveToFile() method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.IDocumentProperty;
import com.spire.presentation.Presentation;
public class deletePresentationProperties {
public static void main(String[] args) throws Exception {
//Create an object of Presentation class
Presentation presentation = new Presentation();
//Load a PowerPoint presentation
presentation.loadFromFile("AddProperties.pptx");
//Get the properties of the presentation and set the properties to null
IDocumentProperty property = presentation.getDocumentProperty();
property.setTitle("");
property.setSubject("");
property.setAuthor("");
property.setManager("");
property.setCompany("");
property.setCategory("");
property.setKeywords("");
property.setComments("");
//Save the presentation file
presentation.saveToFile("DeleteProperties.pptx", FileFormat.AUTO);
presentation.dispose();
}
}
