Public API Changes
Inheritance from ICollection and generic IEnumerable interfaces have been added to ISmartArtNodeCollection

The class Aspose.Slides.SmartArt.SmartArtNodeCollection (and related interface  Aspose.Slides.SmartArt.ISmartArtNodeCollection) inherit generic interface IEnumerable<ISmartArtNode> and interface ICollection.
SmartArtLayoutType.Custom enum value has been added

This type of SmartArt layout represents diagram with custom template. Custom diagrams only can be loaded from presentation file and can't be created via method ShapeCollection.AddSmartArt(x, y, width, height, SmartArtLayoutType.Custom)
SmartArtShape class and ISmartArtShape interface have been added

The Aspose.Slides.SmartArt.SmartArtShape class (and its interface Aspose.Slides.SmartArt.ISmartArtShape) add access to individual shapes inside SmartArt diagram. SmartArtShape can be used to change FillFormat, LineFormat, adding Hyperlinks etc.

Note: SmartArtShape does not supported IShape properties RawFrame, Frame, Rotation, X, Y, Width, Height and thrown System.NotSupportedException when attempting to access them.

Example of usage:

using (Presentation pres = new Presentation())
{
 ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicBlockList);
 ISmartArtNode node = smart.AllNodes[0];
 foreach (SmartArtShape shape in node.Shapes)
 {
   shape.FillFormat.FillType = FillType.Solid;
   shape.FillFormat.SolidFillColor.Color = Color.Red;
 }
 pres.Save("out.pptx", Export.SaveFormat.Pptx);
}

SmartArtShapeCollection class, ISmartArtShapeCollection interface and ISmartArtNode.Shapes property have been added

The Aspose.Slides.SmartArt.SmartArtShapeCollection class (and its interface Aspose.Slides.SmartArt.ISmartArtShapeCollection) add access to individual shapes inside SmartArt diagram. Collection contains shapes associated with SmartArtNode. Property SmartArtNode.Shapes returns collections of all shapes associated with the node.

Note: depending of SmartArtLayoutType one SmartArtShape can be shared between several nodes.

using (Presentation pres = new Presentation())
{
 ISmartArt smart = pres.Slides[0].Shapes.AddSmartArt(10, 10, 400, 300, SmartArtLayoutType.BasicBlockList);
 ISmartArtNode node = smart.AllNodes[0];
 foreach (SmartArtShape shape in node.Shapes)
 {
   shape.FillFormat.FillType = FillType.Solid;
   shape.FillFormat.SolidFillColor.Color = Color.Red;
 }
 pres.Save("out.pptx", Export.SaveFormat.Pptx);
}

Methods for saving presentation slides with page numbers keeping have been added

The following methods have been added:

void IPresentation.Save(string fname, int[] slides, SaveFormat format);

void IPresentation.Save(string fname, int[] slides, SaveFormat format, ISaveOption options);

void IPresentation.Save(Stream stream, int[] slides, SaveFormat format);

void IPresentation.Save(Stream stream, int[] slides, SaveFormat format, ISaveOption options);

These methods allow to save specified presentation slides to PDF, XPS, TIFF, HTML formats. The 'slides' array allows to specify page numbers, starting from 1.
Save(string fname, int[] slides, SaveFormat format);

Presentation presentation = new Presentation(presentationFileName);
int[] slides = new int[] { 2, 3, 5 }; //Array of slides positions
presentation.Save(outFileName, slides, SaveFormat.Pdf);

Methods for image replacing have been added to PPImage, IPPImage

New methods added:

IPPImage.ReplaceImage(byte[] newImageData)
IPPImage.ReplaceImage(Image newImage)
IPPImage.ReplaceImage(IPPImage newImage)

Presentation presentation = new Presentation(presentation.pptx);

//the first way
byte[] data = File.ReadAllBytes(image0.jpeg);
IPPImage oldImage = presentation.Images[0];
oldImage.ReplaceImage(data);

//the second way
Image newImage = Image.FromFile(image1.png);
oldImage = presentation.Images[1];
oldImage.ReplaceImage(newImage);

//the third way
oldImage = presentation.Images[2];
oldImage.ReplaceImage(presentation.Images[3]);

presentation.Save(presentation_out.pptx, SaveFormat.Pptx);
