Use the following code to add a background to your presentation:

Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    // Configure the slide background to use a stretched picture fill.
    slide.getBackground().setType(BackgroundType.OwnBackground);
    slide.getBackground().getFillFormat().setFillType(FillType.Picture);
    slide.getBackground().getFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillMode.Stretch);

    // Load the image from disk.
    byte[] imageData = Files.readAllBytes(Paths.get("image.jpg"));
    IPPImage image = presentation.getImages().addImage(imageData);

    // Set the image as the slide background.
    slide.getBackground().getFillFormat().getPictureFillFormat().getPicture().setImage(image);

    presentation.save("background.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}

Convert Presentations to PDF in Java

PDF is a common format for sharing presentations because it preserves layout and can be opened on many devices without PowerPoint.

Use the following code to convert a PowerPoint presentation to PDF:

Presentation presentation = new Presentation("presentation.ppt");
try {
    presentation.save("output.pdf", SaveFormat.Pdf);
} finally {
    presentation.dispose();
}

try {
    presentation.getSlides().addFromPdf("input.pdf");
    presentation.save("presentation.pptx", SaveFormat.Pptx);
} finally {
    presentation.dispose();
}

Convert PowerPoint Slides to JPG in Java

Slide thumbnails can be used in many scenarios, such as building an online presentation viewer for a custom website, sharing slide previews with customers, or displaying presentation templates. Aspose.Slides for Java allows you to create slide thumbnails with just a few lines of code.

Create a slide thumbnail in Java


Presentation presentation = new Presentation("presentation.pptx");
try {
    for (ISlide slide : presentation.getSlides()) {
        // Render the slide to an image using the specified scale factors.
        IImage image = slide.getImage(2f, 2f);

        // Save the image to disk in JPEG format.
        String fileName = String.format("slide_%d.jpg", slide.getSlideNumber());
        image.save(fileName, ImageFormat.Jpeg);

        image.dispose();
    }
} finally {
    presentation.dispose();
