Public API Changes

MorphTransition class and IMorphTransition interface have been added

The com.aspose.slides.IMorphTransition interface and it’s implementation by com.aspose.slides.MorphTransition class have been added. They represent a new morph transition introduced in PowerPoint 2019.

Morph value has been added into TransitionType enumeration

com.aspose.slides.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:

Presentation presentation = new Presentation();
try
{
    AutoShape autoshape = (AutoShape)presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 400, 100);
    autoshape.getTextFrame().setText("Test text");

    presentation.getSlides().addClone(presentation.getSlides().get_Item(0));

    IShape shape = presentation.getSlides().get_Item(1).getShapes().get_Item(0);
    shape.setX(shape.getX() + 100);
    shape.setY(shape.getY() + 50);
    shape.setWidth(shape.getWidth() - 200);
    shape.setHeight(shape.getHeight() - 10);

    presentation.getSlides().get_Item(1).getSlideShowTransition().setType(com.aspose.slides.TransitionType.Morph);

    presentation.save("presentation-out.pptx", SaveFormat.Pptx);
}
finally {
    presentation.dispose();
}

New TransitionMorphType enum has been added

New com.aspose.slides.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:

Presentation presentation = new Presentation("presentation.pptx");
try
{
    presentation.getSlides().get_Item(0).getSlideShowTransition().setType(TransitionType.Morph);
    ((IMorphTransition)presentation.getSlides().get_Item(0).getSlideShowTransition().getValue()).setMorphType(TransitionMorphType.ByWord);
    presentation.save("presentation-out.pptx", SaveFormat.Pptx);
}
finally
{
    presentation.dispose();
}
