Create or Manage PowerPoint SmartArt Shape Node

Add SmartArt Node in PowerPoint Presentation using PHP

Aspose.Slides for PHP via Java has provided the simplest API to manage the SmartArt shapes in an easiest way. The following sample code will help to add node and child node inside SmartArt shape.

Create an instance of Presentation class and load the presentation with SmartArt Shape.
Obtain the reference of first 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.
Add a new Node in SmartArt shape NodeCollection and set the text in TextFrame.
Now, Add a Child Node in newly added SmartArt Node and set the text in TextFrame
Save the Presentation.

  # Load the desired the presentation
  $pres = new Presentation("SimpleSmartArt.pptx");
  try {
    # Traverse through every shape inside first slide
    foreach($pres->getSlides()->get_Item(0)->getShapes() as $shape) {

      if (java_instanceof($shape, new JavaClass("com.aspose.slides.SmartArt"))) {
        # Typecast shape to SmartArt
        $smart = $shape;
        # Adding a new SmartArt Node
        $TemNode = $smart->getAllNodes()->addNode();
        # Adding text
        $TemNode->getTextFrame()->setText("Test");
        # Adding new child node in parent node. It will be added in the end of collection
        $newNode = $TemNode->getChildNodes()->addNode();
        # Adding text
        $newNode->getTextFrame()->setText("New Node Added");
      }
    }
    # Saving Presentation
    $pres->save("AddSmartArtNode.pptx", SaveFormat::Pptx);

Set Custom Position for Child Node in SmartArt

Now Aspose.Slides for PHP via Java support for setting SmartArtShape X and Y properties. The code snippet below shows how to set custom SmartArtShape position, size and rotation also please note that adding new nodes causes a recalculation of the positions and sizes of all nodes. Also with custom position settings, user may set the nodes as per requirements.

  # Instantiate Presentation Class
  $pres = new Presentation("SimpleSmartArt.pptx");
  try {
    $smart = $pres->getSlides()->get_Item(0)->getShapes()->addSmartArt(20, 20, 600, 500, SmartArtLayoutType::OrganizationChart);
    # Move SmartArt shape to new position
    $node = $smart->getAllNodes()->get_Item(1);
    $shape = $node->getShapes()->get_Item(1);
    $shape->setX($shape->getX() . $shape->getWidth() * 2);
    $shape->setY($shape->getY() - $shape->getHeight() * 2);
    # Change SmartArt shape's widths
    $node = $smart->getAllNodes()->get_Item(2);
    $shape = $node->getShapes()->get_Item(1);
    $shape->setWidth($shape->getWidth() . $shape->getWidth() * 2);
    # Change SmartArt shape's height
    $node = $smart->getAllNodes()->get_Item(3);
    $shape = $node->getShapes()->get_Item(1);
    $shape->setHeight($shape->getHeight() . $shape->getHeight() * 2);
    # Change SmartArt shape's rotation
    $node = $smart->getAllNodes()->get_Item(4);
    $shape = $node->getShapes()->get_Item(1);
    $shape->setRotation(90);
    $pres->save("SmartArt.pptx", SaveFormat::Pptx);
  } finally {
    $pres->dispose();
  }

Check Assistant Node

In this article we will further investigate features of SmartArt shapes added in presentation slides programmatically using Aspose.Slides for PHP via Java.

We will use the following source SmartArt shape for our investigation in different sections of this article.


Figure: Source SmartArt shape in slide

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.

  # Creating a presentation instance
  $pres = new Presentation("AddNodes.pptx");
  try {
    # Traverse through every shape inside first slide
    foreach($pres->getSlides()->get_Item(0)->getShapes() as $shape) {)
      # Check if shape is of SmartArt type
      if (java_instanceof($shape, new JavaClass("com.aspose.slides.SmartArt"))) {
        # Typecast shape to SmartArt
        $smart = $shape;
        # Traversing through all nodes of SmartArt shape
        for($i = 0; $i < java_values($smart->getAllNodes()->size()) ; $i++) {
          $node = $smart->getAllNodes()->get_Item($i);
          # Check if node is Assistant node
          if ($node->isAssistant()) {
            # Setting Assistant node to false and making it normal node
            $node->isAssistant();
          }
        }
      }
    }
    # Save Presentation
    $pres->save("ChangeAssitantNode.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();

Set Node’s Fill Format

Aspose.Slides for PHP via Java makes it possible to add custom SmartArt shapes and set their fill format. This article explains how to create and access SmartArt shapes and set their fill format using Aspose.Slides for PHP via Java.

Please follow the steps below:

Create an instance of the Presentation class.
Obtain the reference of a slide using its index.
Add a SmartArt shape by setting its LayoutType.
Set the FillFormat for the SmartArt shape nodes.
Write the modified presentation as a PPTX file.

  # Instantiate the presentation
  $pres = new Presentation();
  try {
    # Accessing the slide
    $slide = $pres->getSlides()->get_Item(0);
    # Adding SmartArt shape and nodes
    $chevron = $slide->getShapes()->addSmartArt(10, 10, 800, 60, SmartArtLayoutType::ClosedChevronProcess);
    $node = $chevron->getAllNodes()->addNode();
    $node->getTextFrame()->setText("Some text");
    # Setting node fill color
    foreach($node->getShapes() as $item) {
      $item->getFillFormat()->setFillType(FillType::Solid);
      $item->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->RED);
    }
    # Save the presentation
    $pres->save("TestSmart.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Generate Thumbnail of SmartArt Child Node

Developers can generate a thumbnail of Child node of a SmartArt by following the steps below:

Create an instance of Presentation class.
Add SmartArt.
Obtain the reference of a node by using its Index
Get the thumbnail image.
Save the thumbnail image in any desired image format.

  # Instantiate Presentation class that represents the PPTX file
  $pres = new Presentation();
  try {
    # Add SmartArt
    $smart = $pres->getSlides()->get_Item(0)->getShapes()->addSmartArt(10, 10, 400, 300, SmartArtLayoutType::BasicCycle);
    # Obtain the reference of a node by using its Index
    $node = $smart->getNodes()->get_Item(1);
    # Get thumbnail
    $slideImage = $node->getShapes()->get_Item(0)->getImage();
    # Save thumbnail
    try {
      $slideImage->save("SmartArt_ChildNote_Thumbnail.png", ImageFormat::Png);
    } finally {
      if (!java_is_null($slideImage)) {
