When I try to run the example of “Create or clone existing slides from templates”, just amend the image “image.jpg” to “image.webp”, the throw NullPointerException.

os:Windows11
version: com.aspose:aspose-slides:24.3:jdk16
code like:


Presentation pres = new Presentation();
try {
    // Sets conditions for background image
    pres.getSlides().get_Item(0).getBackground().setType(BackgroundType.OwnBackground);
    pres.getSlides().get_Item(0).getBackground().getFillFormat().setFillType(FillType.Picture);
    pres.getSlides().get_Item(0).getBackground().getFillFormat().getPictureFillFormat()
            .setPictureFillMode(PictureFillMode.Stretch);
    
    // Loads the image
    IPPImage imgx = pres.getImages().addImage(Files.readAllBytes(Paths.get("image.webp")));
    
    // Adds image to presentation's images collection
    pres.getSlides().get_Item(0).getBackground().getFillFormat().getPictureFillFormat().getPicture().setImage(imgx);
    
    // Writes the presentation to disk
    pres.save("ContentBG_Img.pptx", SaveFormat.Pptx);
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

@wiiyaya,
Thank you for describing the issue. Could you kindly compress the “image.webp” file you used into a zip archive and upload it here?
