This article demonstrates how to insert an audio file (.wav) in a presentation slide by using Spire.Presentation for Java.
import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;
import java.awt.*;
import java.awt.geom.Rectangle2D;
public class InsertAudio {
public static void main(String[] args) throws Exception {
//create a Presentation object and load an example PowerPoint file
Presentation presentation = new Presentation();
presentation.loadFromFile("C:/Users/Administrator/Desktop/example.pptx");
//add a shape to the first slide
Rectangle2D.Double labelRect= new Rectangle2D.Double(50, 120, 100, 50);
IAutoShape labelShape = presentation.getSlides().get(0).getShapes().appendShape(ShapeType.RECTANGLE, labelRect);
labelShape.getLine().setFillType(FillFormatType.NONE);
labelShape.getFill().setFillType(FillFormatType.NONE);
labelShape.getTextFrame().setText("Audio:");
labelShape.getTextFrame().getTextRange().setFontHeight(28);
labelShape.getTextFrame().getTextRange().setLatinFont(new TextFont("Myriad Pro Light"));
labelShape.getTextFrame().getTextRange().getFill().setFillType(FillFormatType.SOLID);
labelShape.getTextFrame().getTextRange().getFill().getSolidColor().setColor(Color.BLACK);
//append an audio file to the slide
Rectangle2D.Double audioRect = new Rectangle2D.Double(170, 120, 50, 50);
presentation.getSlides().get(0).getShapes().appendAudioMedia((new java.io.File("C:/Users/Administrator/Desktop/Music.wav")).getAbsolutePath(), audioRect);
//save to file
presentation.saveToFile("output/InsertAudio.pptx", FileFormat.PPTX_2010);
presentation.dispose();
}
}
