Prerequisites

Before diving into using Aspose.Slides for Java to highlight text in PowerPoint presentations, ensure you have the following prerequisites set up:

  • Java Development Kit (JDK): Make sure you have Java installed on your system. You can download it from Java SE Development Kit Downloads.
  • Aspose.Slides for Java Library: Obtain the Aspose.Slides for Java library from the download page. Follow the installation instructions to set up the library in your development environment.
  • Integrated Development Environment (IDE): Choose an IDE of your preference that supports Java development, such as IntelliJ IDEA, Eclipse, or NetBeans.

Import Packages

To get started with highlighting text in PowerPoint presentations using Aspose.Slides for Java, you need to import the necessary packages:

import com.aspose.slides.*;
import java.awt.*;

Step 1: Load the Presentation

First, load the PowerPoint presentation where you want to highlight text.

String dataDir = "Your Document Directory";
Presentation presentation = new Presentation(dataDir + "SomePresentation.pptx");

Replace "Your Document Directory" with the actual directory path where your PowerPoint presentation (SomePresentation.pptx) is located.

Step 2: Highlight Text

Highlight specific text within a shape on the slide. Here, we highlight occurrences of the word “title” and “to” with different colors.

// Highlighting the word 'title' with LightBlue color
((AutoShape) presentation.getSlides().get_Item(0).getShapes().get_Item(0))
    .getTextFrame().highlightText("title", new Color(PresetColor.LightBlue));
// Highlighting the word 'to' with Violet color, whole words only
TextHighlightingOptions options = new TextHighlightingOptions();
options.setWholeWordsOnly(true);
((AutoShape) presentation.getSlides().get_Item(0).getShapes().get_Item(0))
    .getTextFrame().highlightText("to", new Color(PresetColor.Violet), options);

This code snippet demonstrates how to highlight text within a specified shape (AutoShape) on the first slide (get_Item(0)).

Step 3: Save the Modified Presentation

Save the modified presentation with the highlighted text to a new file.

presentation.save(dataDir + "SomePresentation-out.pptx", SaveFormat.Pptx);

Replace "SomePresentation-out.pptx" with the desired name for your output file.

Conclusion

In conclusion, using Aspose.Slides for Java simplifies the task of programmatically manipulating PowerPoint presentations. With its comprehensive API, developers can efficiently highlight text, customize slides, and automate presentation tasks to enhance productivity.
