Public API Changes

MorphTransition and IMorphTransition classes have been added

Aspose::Slides::SlideShow::MorphTransition and Aspose::Slides::SlideShow::IMorphTransition classes have been added. They represent new morph transition introduced in PowerPoint 2019.

Morph value has been added into TransitionType enumeration (C++)

Aspose::Slides::SlideShow::TransitionType enumeration has been extended with new element Morph related to new PowerPoint 2019 transition Morph.

The code snippet below shows how to add a clone of the slide with some text to the presentation and set a transition of morph type to the second slide:

 {
    auto presentation = System::MakeObject<Presentation>();
    auto autoshape = System::DynamicCast<Aspose::Slides::AutoShape>(presentation->get_Slides()->idx_get(0)->get_Shapes()->AddAutoShape(Aspose::Slides::ShapeType::Rectangle, 100, 100, 400, 100));

    autoshape->get_TextFrame()->set_Text(u"Test text");
    presentation->get_Slides()->AddClone(presentation->get_Slides()->idx_get(0));

    auto x = presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->get_X();
    auto y = presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->get_Y();
    auto width = presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->get_Width();
    auto height = presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->get_Height();

    presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->set_X(x + 100);
    presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->set_Y(y + 50);
    presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->set_Width(width + 200);
    presentation->get_Slides()->idx_get(1)->get_Shapes()->idx_get(0)->set_Height(height + 10);

    presentation->get_Slides()->idx_get(1)->get_SlideShowTransition()->set_Type(Aspose::Slides::SlideShow::TransitionType::Morph);

    presentation->Save(u"presentation-out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
}

New TransitionMorphType enum has been added (C++)

New Aspose::Slides::SlideShow::TransitionMorphType enum has been added. It represents different types of Morph slide transition.

TransitionMorphType enum has three members:

  • ByObject: Morph transition will be performed considering shapes as indivisible objects.
  • ByWord: Morph transition will be performed with transferring text by words where possible.
  • ByChar: Morph transition will be performed with transferring text by characters where possible.

The code snippet below shows how to set morph transition to slide and change morph type:

 {
    auto presentation = System::MakeObject<Presentation>(u"presentation.pptx");

    presentation->get_Slides()->idx_get(0)->get_SlideShowTransition()->set_Type(Aspose::Slides::SlideShow::TransitionType::Morph);

    auto morphTransition = System::DynamicCast<Aspose::Slides::SlideShow::IMorphTransition>(presentation->get_Slides()->idx_get(0)->get_SlideShowTransition()->get_Value());
    morphTransition->set_MorphType(Aspose::Slides::SlideShow::TransitionMorphType::ByWord);

    presentation->Save(u"presentation-out.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
}
