Public API Changes

IVbaProject interface has been added, Presentation.VbaProject property has been changed

VbaProject property of Presentation class has been replaced. Instead of raw bytes VbaProject property representation of VBA project, the new IVbaProject interface implementation added.
Use new IVbaProject to manage VBA Project embedded in the presentation. You can add new project references, edit existing modules and create new ones.
Also, you can create a new VBA Project using VbaProject class which implements IVbaProject interface.
Following example shows creation of the simple VBA project containing one module and adding two required references to the libraries.

using (Presentation pres = new Presentation())
{
   // Create new VBA Project
   pres.VbaProject = new VbaProject();

   // Add empty module to the VBA project
   IVbaModule module = pres.VbaProject.Modules.AddEmptyModule("Module");

   // Set module source code
   module.SourceCode =
       @"Sub Test(oShape As Shape)
           MsgBox ""Test""
       End Sub";

   // Create reference to stdole
   VbaReferenceOleTypeLib stdoleReference =
       new VbaReferenceOleTypeLib("stdole", "*\\G{00020430-0000-0000-C000-000000000046}#2.0#0#C:\\Windows\\system32\\stdole2.tlb#OLE Automation");

   // Create reference to Office
   VbaReferenceOleTypeLib officeReference =
       new VbaReferenceOleTypeLib("Office", "*\\G{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}#2.0#0#C:\\Program Files\\Common Files\\Microsoft Shared\\OFFICE14\\MSO.DLL#Microsoft Office 14.0 Object Library");

   // Add references to the VBA project
   pres.VbaProject.References.Add(stdoleReference);
   pres.VbaProject.References.Add(officeReference);

   pres.Save("test.pptm", SaveFormat.Pptm);
}

This example shows how you can copy VBA project from existing presentation to a newly created

using (Presentation pres1 = new Presentation("PresentationWithMacroses.pptm"), pres2 = new Presentation())
{
   pres2.VbaProject = new VbaProject(pres1.VbaProject.ToBinary());
}

Property Aspose.Slides.Charts.IChartSeries.Overlap has been added

Property Aspose.Slides.Charts.IChartSeries.Overlap specifies how much bars and columns shall overlap on 2-D charts (from -100 to 100).
This is the property not only of this series but of all series of parent series group - this is projection of appropriate group property. And so this property is read-only.
Use ParentSeriesGroup property for access to parent series group.  
Use ParentSeriesGroup.Overlap read/write property for change value.

using (Presentation pres = new Presentation())
{
  IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 50, 50, 600, 400, true);
  IChartSeriesCollection series = chart.ChartData.Series;
  if (series[0].Overlap == 0)
     {
           series[0].ParentSeriesGroup.Overlap = -30;
     }
}

Property Aspose.Slides.Charts.IChartSeriesGroup.Overlap has been added

Property Aspose.Slides.Charts.IChartSeriesGroup.Overlap property specifies how much bars and columns shall overlap on 2-D charts (from -100 to 100).

using (Presentation pres = new Presentation())
{
  IChart chart = pres.Slides[0].Shapes.AddChart(ChartType.ClusteredColumn, 50, 50, 600, 400, true);
  IChartSeriesCollection series = chart.ChartData.Series;
  series[0].ParentSeriesGroup.Overlap = -30;
}

ShapeThumbnailBounds.Appearance enum value has been added

This method of shape thumbnail creation allows to generate a shape thumbnail in the bounds of its appearance. It takes into account all shape effects. The generated shape thumbnail is restricted by slide bounds.

using (Presentation p = new Presentation("Presentation.pptx"))
{
   Bitmap st = p.Slides[0].Shapes[0].GetThumbnail(ShapeThumbnailBounds.Appearance, 1, 1);
   st.Save("ShapeThumbnail.png", ImageFormat.Png);
}
