Checking Assistant Nodes in SmartArt Shapes using Aspose.Slides

Aspose.Slides - Checking Assistant Nodes in SmartArt Shapes

In the following sample code we will investigate how to identify Assistant Nodes in the SmartArt nodes collection and changing them.

  • Create an instance of Presentation class and load the presentation with SmartArt Shape
  • Obtain the reference of second slide by using its Index
  • Traverse through every shape inside first slide
  • Check if shape is of SmartArt type and Typecast selected shape to SmartArt if it is SmartArt
  • Traverse through all nodes inside SmartArt shape and check if they are Assistant Nodes
  • Change the status of Assistant Node to normal node
  • Save the Presentation

Java

 // Creating a presentation instance

Presentation pres = new Presentation(dataDir + "presentation.pptx");

// Traverse through every shape inside first slide

for (IShape shape : pres.getSlides().get_Item(0).getShapes())

{

    // Check if shape is of SmartArt type

    if (shape instanceof ISmartArt)

    {

	// Typecast shape to SmartArtEx

	ISmartArt smart = (SmartArt) shape;

	// Traversing through all nodes of SmartArt shape

	for (int i = 0; i < smart.getAllNodes().size(); i++)

	{

	    ISmartArtNode node = smart.getAllNodes().get_Item(i);

	    String tc = node.getTextFrame().getText();

	    // Check if node is Assistant node

	    if (node.isAssistant())

	    {

		System.out.println(tc + " - true");

		// Setting Assistant node to false and making it normal

		// node

		node.setAssistant(false);

	    }

	    else

	    {

		System.out.println(tc + " - false");

	    }

	}

    }

}

// Save Presentation

pres.save(dataDir + "AsposeChangeAssitantNode.pptx", SaveFormat.Pptx);
