ILayoutSlide layout = ...;
if (!layout.HasDependingSlides)
layout.Remove();
Aspose.Slides.ILayoutSlide.Remove() method had been added
The method Aspose.Slides.ILayoutSlide.Remove() allows to remove layout from presentation with minimum of code. For example:

or
IMasterSlide masterSlide = ...;
masterSlide.LayoutSlides.RemoveUnused();
Aspose.Slides.IMasterSlide.HasDependingSlides property had been added
The property Aspose.Slides.IMasterSlide.HasDependingSlides returns true if there exists at least one slide that depends on this master slide. For example:

using(Presentation presentation = new Presentation())
{
ISmartArt smart = presentation.Slides[0].Shapes.AddSmartArt(10, 10, 500, 400, SmartArtLayoutType.VerticalPictureList);
ISmartArtNode node = smart.AllNodes[0];

if(node.BulletFillFormat != null)
{
Image img = (Image)new Bitmap("sample.jpg");
IPPImage image = presentation.Images.AddImage(img);
node.BulletFillFormat.FillType = FillType.Picture;
node.BulletFillFormat.PictureFillFormat.Picture.Image = image;
node.BulletFillFormat.PictureFillFormat.PictureFillMode = PictureFillMode.Stretch;
}
presentation.Save("out.pptx", SaveFormat.Pptx);
}
Aspose.Slides.SmartArt.ISmartArtNode.Level property has been added
The property Aspose.Slides.SmartArt.ISmartArtNode.Level returns nested level for SmartArt node
ISmartArtNode node = diagram.AllNodes[0];
if(node.Level == 1)

Aspose.Slides.SmartArt.ISmartArtNode.Remove() method had been added
Aspose.Slides.SmartArt.ISmartArtNode.Remove() method allows to remove node from diagram.
ISmartArt node = diagram.AllNodes[0];
node.Remove();
Interface IGlobalLayoutSlideCollection and class GlobalLayoutSlideCollection had been added
Interface IGlobalLayoutSlideCollection and class GlobalLayoutSlideCollection had been added into namespace Aspose.Slides. Class GlobalLayoutSlideCollection implements interface IGlobalLayoutSlideCollection.
Interface IGlobalLayoutSlideCollection represents a collection of all layout slides in presentation. IPresentation.LayoutSlides property is of type IGlobalLayoutSlideCollection. IGlobalLayoutSlideCollection extends ILayoutSlideCollection interface with methods for adding/cloning layout slides in context of uniting of the individual collections of master's layout slides:
ILayoutSlide AddClone(ILayoutSlide sourceLayout);
- allows to add a copy of a specified layout slide to the presentation. This method keep source formatting (when cloning a layout between different presentations layout's master can be cloned too. Internal registry is used to track automatically cloned masters to prevent creation of multiple clones of the same master slide.)
ILayoutSlide AddClone(ILayoutSlide sourceLayout, IMasterSlide destMaster);
- allows to add a copy of a specified layout slide to the presentation. New layout will be linked with defined master in destination presentation. So this is analogue of copy/paste with "Use Destination Theme" option in PowerPoint. ILayoutSlide Add(IMasterSlide master, SlideLayoutType layoutType, string layoutName);
- allows to add a new layout slide to the presentation. Supported layout types: Title, TitleOnly, Blank, TitleAndObject, VerticalText, VerticalTitleAndText, TwoObjects, SectionHeader, TwoTextAndTwoObjects, TitleObjectAndCaption, PictureAndCaption, Custom. Layout name can be generated atomatically. Added layout of type SlideLayoutType.Custom contains no placeholders and no shapes. Analogue of this method is method IMasterLayoutSlideCollection.Add(SlideLayoutType, string) accessed with IMasterSlide.LayoutSlides property.
Interface IMasterLayoutSlideCollection and class MasterLayoutSlideCollection had been added
Interface IMasterLayoutSlideCollection and class MasterLayoutSlideCollection had been added into namespace Aspose.Slides. Class MasterLayoutSlideCollection implements interface IMasterLayoutSlideCollection.
Interface IMasterLayoutSlideCollection represents a collections of all layout slides of defined master slide. It extends ILayoutSlideCollection interface with methods for adding/inserting/removing/cloning layout slides in context of the individual collections of master's layout slides:
// method signature:
ILayoutSlide AddClone(ILayoutSlide sourceLayout);
// code example that attaches copy of the sourceLayout to the destMasterSlide:
IMasterSlide destMasterSlide = ...;
destMasterSlide.LayoutSlides.AddClone(sourceLayout);
- allows to add a copy of a specified layout slide to the end of the collection. New layout will be linked with parent master slide for this layout slides collection. So this is analogue of copy/paste with "Use Destination Theme" option in PowerPoint. Analogue of this method is method IGlobalLayoutSlideCollection.AddClone(ILayoutSlide, IMasterSlide) accessed with IPresentation.LayoutSlides property.
ILayoutSlide InsertClone(int index, ILayoutSlide sourceLayout);
- allows to insert a copy of a specified layout slide to specified position of the collection. New layout will be linked with parent master slide for this layout slides collection. So this is analogue of copy/paste with "Use Destination Theme" option in PowerPoint.
ILayoutSlide Add(SlideLayoutType layoutType, string layoutName);
ILayoutSlide Insert(int index, SlideLayoutType layoutType, string layoutName);
- allows to add/inserts a new layout slide. Supported layout types: Title, TitleOnly, Blank, TitleAndObject, VerticalText, VerticalTitleAndText, TwoObjects, SectionHeader, TwoTextAndTwoObjects, TitleObjectAndCaption, PictureAndCaption, Custom. Layout name can be generated atomatically. Added layout of type SlideLayoutType.Custom contains no placeholders and no shapes. Analogue of this method is method IGlobalLayoutSlideCollection.Add(IMasterSlide, SlideLayoutType, string) accessed with IPresentation.LayoutSlides property.
void RemoveAt(int index);
- allows to remove the layout at the specified index of the collection.
void Reorder(int index, ILayoutSlide layoutSlide);
- allows to move layout slide from the collection to the specified position.
Signature of the Aspose.Slides.ISlideCollection.AddClone(ISlide, IMasterSlide) method has been changed
Signature of the ISlideCollection method
ISlide AddClone(ISlide sourceSlide, IMasterSlide destMaster);
is obsolete now and is replaced with signature
ISlide AddClone(ISlide sourceSlide, IMasterSlide destMaster, bool allowCloneMissingLayout)
Parameter "allowCloneMissingLayout" specify what to do if there is no appropriate layout in "destMaster" for new (cloned) slide. Appropriate layout is the layout with the same Type or Name as of layout of the source slide. If there is no appropriate layout in specified master then layout of the source slide will be cloned (if allowCloneMissingLayout is true) or PptxEditException will be thrown (if allowCloneMissingLayout is false).
Call of the obsolete method like
AddClone(sourceSlide, destMaster);
assumes "allowCloneMissingLayout" is equal to false (i.e. PptxEditException will be thrown if there is no appropriate layout). Functionally identical call that uses new signature looks as
AddClone(sourceSlide, destMaster, false);
If you want missing layouts to be automatically cloned instead PptxEditException throwing then pass "allowCloneMissingLayout" parameter true.
The same refers to the ISlideCollection method
ISlide InsertClone(int index, ISlide sourceSlide, IMasterSlide destMaster);
that is also obsolete now and is replaced with signature
ISlide InsertClone(int index, ISlide sourceSlide, IMasterSlide destMaster, bool allowCloneMissingLayout);
Type of the Aspose.Slides.IMasterSlide.LayoutSlides property has been changed
Type of the Aspose.Slides.IMasterSlide.LayoutSlides property has been changed from ILayoutSlideCollection to new IMasterLayoutSlideCollection interface. IMasterLayoutSlideCollection interface is the descendant of the ILayoutSlideCollection so user code needs no adaptations.
Type of the Aspose.Slides.IPresentation.LayoutSlides property has been changed
Type of the Aspose.Slides.IPresentation.LayoutSlides property has been changed from ILayoutSlideCollection to new IGlobalLayoutSlideCollection interface. IGlobalLayoutSlideCollection interface is the descendant of the ILayoutSlideCollection so user code needs no adaptations.
