Detailed Description

Represents a base class for collection of a layout slides.

Member Function Documentation

◆ GetByType()

virtual System::SharedPtr<ILayoutSlide> Aspose::Slides::ILayoutSlideCollection::GetByType ( SlideLayoutType  type)
pure virtual

Returns the first layout slide of specified type.

Parameters
typeA type of layout slide to find.
Returns
ILayoutSlide with specified type or null if no layouts found.

Implemented in Aspose::Slides::LayoutSlideCollection.

◆ idx_get()

virtual System::SharedPtr<ILayoutSlide> Aspose::Slides::ILayoutSlideCollection::idx_get ( int32_t  index)
pure virtual

Returns the layout slide by index. Read-only ILayoutSlide.

Implemented in Aspose::Slides::LayoutSlideCollection.

◆ Remove()

virtual void Aspose::Slides::ILayoutSlideCollection::Remove ( System::SharedPtr< ILayoutSlide value)
pure virtual

Removes a layout from the collection.

Parameters
valueThe layout slide to remove from the collection.
Exceptions
PptxEditExceptionThrown if layout is used in presentation (its HasDependingSlides property is true).

1) To avoid throwing of the PptxEditException check layout's HasDependingSlides property before. 2) You can use also ILayoutSlide::Remove() method to simplify code.

Implemented in Aspose::Slides::LayoutSlideCollection.

◆ RemoveUnused()

virtual void Aspose::Slides::ILayoutSlideCollection::RemoveUnused ( )
pure virtual

Removes unused layout slides (layout slides whose HasDependingSlides is false).

Implemented in Aspose::Slides::LayoutSlideCollection.
