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);
}
}
