## **Public API Changes**
### **Added the Aspose.Slides.Charts.IChartSeries.getOverlap(), IChartSeriesGroup.getOverlap(), and setOverlap(byte) Mehtods**
The Aspose.Slides.Charts.IChartSeries.getOverlap() gets how much bars and columns should overlap on 2D charts (in a range from -100 to 100).
This method is not only for specific series but for all series of the parent series group - this is projection of the appropriate group property.

- Use IChartSeries.getParentSeriesGroup() method for accessing to parent series group.
- Use IChartSeriesGroup.getOverlap() and setOverlap(byte) methods to manage the value.

``` java
import com.aspose.slides.*;


 Presentation pres = new Presentation();

IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.ClusteredColumn, 50, 50, 600, 400, true);

IChartSeriesCollection series = chart.getChartData().getSeries();

if (series.get_Item(0).getOverlap() == 0) {

  series.get_Item(0).getParentSeriesGroup().setOverlap((byte)-30);

}

```
### **Added the ShapeThumbnailBounds.Appearance Enum Value**
This method of creating shape thumbnails allows developers 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 the slide bounds.

``` java
import com.aspose.slides.*;


 Presentation pres = new Presentation("Presentation.pptx");

IImage st = pres.getSlides().get_Item(0).getShapes().get_Item(0).getImage(ShapeThumbnailBounds.Appearance, 1, 1);

```
### **Added the VbaProject Class and IVbaProject Interface, Changed the Presentation.getVbaProject() and setVbaProject(VbaProject) Methods**
A new feature allows developers to create and edit VBA projects in a presentation.

``` java
import com.aspose.slides.*;


 Presentation pres = new Presentation();

// Create new VBA Project

pres.setVbaProject(new VbaProject());

// Add empty module to the VBA project

IVbaModule module = pres.getVbaProject().getModules().addEmptyModule("Module");

// Set module source code

module.setSourceCode("Sub Test(oShape As Shape)\r\n    MsgBox \"Test\"\r\nEnd 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.getVbaProject().getReferences().add(stdoleReference);

pres.getVbaProject().getReferences().add(officeReference);

pres.save("test.pptm", SaveFormat.Pptm);

```
