In the process of daily work, we may sometimes encounter a situation where we need to replace the image in a PowerPoint document. And Free Spire.Presentation for Java provides us a method to replace an existing image with a new image in Java application. In this article, I will share the Java code used.

Import Jar Dependency

Method 1: Download the Free Spire.Presentation for Java and unzip it. Then add the Spire.Presentation.jar file to your project as dependency.

Method 2: You can also add the jar dependency to your maven project by adding the following configurations to the pom.xml.

Replace Image

import com.spire.presentation.*;
import com.spire.presentation.drawing.IImageData;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.FileInputStream;

public class ReplaceImage {

    public static void main(String[] args) throws Exception {

        //create a Presentation object
        Presentation presentation= new Presentation();

        //load the sample PowerPoint file
        presentation.loadFromFile("Polar bears.pptx");

        //add an image to the image collection
        String imagePath = "C:\\Users\\Administrator\\Desktop\\p1.jpg";
        BufferedImage bufferedImage = ImageIO.read(new FileInputStream(imagePath));
        IImageData image = presentation.getImages().append(bufferedImage);

        //get the shape collection from the first slide
        ShapeCollection shapes = presentation.getSlides().get(0).getShapes();

        //loop through the shape collection
        for (int i = 0; i < shapes.getCount(); i++) {

            //determine if a shape is a picture
            if (shapes.get(i) instanceof SlidePicture) {

                //fill the shape with a new image
                ((SlidePicture) shapes.get(i)).getPictureFill().getPicture().setEmbedImage(image);
            }
        }

        //save to file
        presentation.saveToFile("ReplaceImage.pptx", FileFormat.PPTX_2013);
    }
