Background Is Not Applied for a PowerPoint Presentation Slide

Aspose.PDF Product Family

#1

Hi,

I am converting some PDF to PPTX and applying a custom background to each slide after conversion. On one PDF the content is covering the background completely. I’ve shared the sample code and PDF that reproduces the problem.

var theme = new Presentation("src/main/java/" + themeName + ".pptx");

try (Document document = new Document("src/main/java/" + fileName + ".pdf")) {
    var secondPage = document.getPages().get_Item(2);
    var width = secondPage.getRect().getWidth();
    var height = secondPage.getRect().getHeight();

    // Set size of first page
    document.getPages().get_Item(1).setPageSize(width, height);
    document.save(fileName + ".pptx", SaveFormat.Pptx);

    var presentation = new Presentation(fileName + ".pptx");
    presentation.getSlideSize().setOrientation(SlideOrientation.Landscape);

    var sourceSlide = theme.getSlides().get_Item(0);

    IMasterSlide sourceMaster = sourceSlide.getLayoutSlide().getMasterSlide();

    var slideMaster = presentation.getMasters().addClone(sourceMaster);

    for (var slide : presentation.getSlides()) {
        slide.getLayoutSlide().setMasterSlide(slideMaster);
        if (sourceSlide.getShowMasterShapes())
            slide.setShowMasterShapes(sourceSlide.getShowMasterShapes());
    }
    for (var slide : presentation.getSlides()) {
        slide.getSlideShowTransition().setType(TransitionType.Fade);
    }
    presentation.save(fileName + ".pptx", com.aspose.slides.SaveFormat.Pptx);
}

@srijal,
As far as I can see, the background is applied correctly for every slide in the presentation, but a shape on the second slide completely covers the background. output.png (200.4 KB)
Could you please describe the problem?

Hi,

Thanks for taking a look. Yeah, there is a shape covering the slide and hiding the background. But I think this shouldn’t be there. The second page is correctly converted without any page-spanning shape. Is the problem in the conversion or is the image on the PDF not correctly made?

Issue also exists in another PDF attached below:

@srijal,
Please note that the shape completely covering the slide appears without using Aspose.Slides:

try (Document document = new Document("CC.pdf")) {
    var secondPage = document.getPages().get_Item(2);
    var width = secondPage.getRect().getWidth();
    var height = secondPage.getRect().getHeight();

    document.getPages().get_Item(1).setPageSize(width, height);
    document.save("output.pptx", com.aspose.pdf.SaveFormat.Pptx);
}

I moved this forum thread to the Aspose.Pdf forum. My colleagues will check the issue and get back to you as soon as possible.
