get_SolidFillColor Method Returns Incorrect Value from Presentation Shape in C++

  • version:aspose-slides-cpp-windows-23.1
  • The fill color obtained by the following code is incorrect
void PrintFillFormat(System::String pptFilePath)
    System::SharedPtr<System::IO::FileStream> stream = System::MakeObject<System::IO::FileStream>(pptFilePath, System::IO::FileMode::Open, System::IO::FileAccess::Read, System::IO::FileShare::ReadWrite);
    System::SharedPtr<Aspose::Slides::Presentation> presentation = System::MakeObject<Aspose::Slides::Presentation>(stream);
    System::SharedPtr<ISlideCollection> slides = presentation->get_Slides();
    for (int slideIdx = 0; slideIdx < slides->get_Count(); slideIdx++)
        System::SharedPtr<Aspose::Slides::ISlide> slide = slides->idx_get(slideIdx);
        System::SharedPtr<IShapeCollection> shapes = slide->get_Shapes();
        for (int i = 0, n = shapes->get_Count(); i < n; i++)
            System::SharedPtr<IShape> shape = shapes->idx_get(i);
            System::SharedPtr<IFillFormatEffectiveData> fillFormat = shape->get_FillFormat()->GetEffective();
            Aspose::Slides::FillType fillType = fillFormat->get_FillType();
            if (fillType == Aspose::Slides::FillType::Solid) {
                System::Drawing::Color color = fillFormat->get_SolidFillColor();
                System::Console::WriteLine(u"color:{0}", color);
  • Code console output:“color:Color [A=255, R=175, G=171, B=171]”,The right transparency is A=0

I reproduced the problem with retrieving the fill color value from the shape.

Our developers have investigated the case. PowerPoint can’t handle this presentation correctly. shape_settings.png (76.4 KB). As you can see, the Transparency value is set to 0%, which means complete opacity. However, PowerPoint displays the background of the shape as transparent. It should also be noted that changing the Transparency and Color values of this shape has no effect on its display.

This is not a bug in Aspose.Slides. It is not a transparency issue but it is a document issue. Examining the document showed that the shape is missing the a:prstGeom tag.
