try {
    const slideCount = presentation.getSlides().size();
    for (let slideIndex = 0; slideIndex < slideCount; slideIndex++) {
        const slide = presentation.getSlides().get_Item(slideIndex);
        const slideImage = slide.getImage(2, 2);
        try {
            const filePath = "slide_" + slide.getSlideNumber() + ".bmp";
            slideImage.save(filePath, aspose.slides.ImageFormat.Bmp);
        }
        finally {
            slideImage.dispose();
