Public API Changes

AutoShape::get_IsTextBox() method has been added

AutoShape::get_IsTextBox() method has been added to indicate if the shape was created as a text box or not. The screenshot below demonstrates two scenarios when a shape will be created as a text box and a regular shape:

Text box and shape

This code snippet demonstrates iteration over all Presentation shapes and out to console if the shape is a text box or not (if the shape is AutoShape).

auto pres = System::MakeObject<Presentation>(u"pres.pptx");
for (auto&& slide : pres->get_Slides())
    for (auto&& shape : slide->get_Shapes())
        auto autoShape = System::DynamicCast_noexcept<Aspose::Slides::AutoShape>(shape);
        if (autoShape != nullptr)
            System::Console::WriteLine(autoShape->get_IsTextBox() ? System::String(u"shape is text box") : System::String(u"shape is not text box"));

Classes inherited from EffectEffectiveData removed from public API

The follwoing classes that inherited from EffectEffectiveData were removed from the public API:

  • AlphaBiLevelEffectiveData
  • AlphaModulateFixedEffectiveData
  • AlphaReplaceEffectiveData
  • BiLevelEffectiveData
  • BlurEffectiveData
  • ColorChangeEffectiveData
  • ColorReplaceEffectiveData
  • DuotoneEffectiveData
  • FillOverlayEffectiveData
  • GlowEffectiveData
  • HSLEffectiveData
  • InnerShadowEffectiveData
  • LuminanceEffectiveData
  • OuterShadowEffectiveData
  • PresetShadowEffectiveData
  • ReflectionEffectiveData
  • SoftEdgeEffectiveData
  • TintEffectiveData

All effective values are still available via corresponding public interfaces, e.g.:

using namespace Aspose::Slides;

void portion_callback(System::SharedPtr<Portion> portion, System::SharedPtr<Paragraph> para, System::SharedPtr<BaseSlide> slide, int32_t index)
    System::SharedPtr<IPortionFormatEffectiveData> effective = portion->get_PortionFormat()->GetEffective();

int main()
    auto pres = System::MakeObject<Presentation>(u"pres.pptx");
    LowCode::ForEach::Portion(pres, portion_callback);
