Clone Slides

Clone Slides in Presentation

Cloning is the process of making an exact copy or replica of something. Aspose.Slides for PHP via Java also makes it possible to make a copy or clone of any slide and then insert that cloned slide to the current or any other opened presentation. The process of slide cloning creates a new slide that can be modified by developers without changing the original slide. There are several possible ways to clone a slide:

  • Clone at End within a Presentation.
  • Clone at Another Position within Presentation.
  • Clone at End in another Presentation.
  • Clone at Another Position in another Presentation.
  • Clone at a specific position in another Presentation.

In Aspose.Slides for PHP via Java, (a collection of ISlide objects) exposed by the Presentation object provides the addClone and insertClone methods to perform the above types of slide cloning

Clone at End within a Presentation

If you want to clone a slide and then use it within the same presentation file at the end of the existing slides, use the addClone method according to the steps listed below:

  1. Create an instance of the Presentation class.
  2. Instantiate the ISlideCollection class by referencing the Slides collection exposed by the Presentation object.
  3. Call the addClone method exposed by the ISlideCollection object and pass the slide to be cloned as a parameter to the addClone method.
  4. Write the modified presentation file.

In the example given below, we have cloned a slide (lying at the first position – zero index – of the presentation) to the end of the presentation.

  # Instantiate Presentation class that represents a presentation file
  $pres = new Presentation("CloneWithinSamePresentationToEnd.pptx");
  try {
    # Clone the desired slide to the end of the collection of slides in the same presentation
    $slds = $pres->getSlides();
    $slds->addClone($pres->getSlides()->get_Item(0));
    # Write the modified presentation to disk
    $pres->save("Aspose_CloneWithinSamePresentationToEnd_out.pptx", SaveFormat::Pptx);
  } finally {
    $pres->dispose();
  }

Clone at Another Position with in Presentation

If you want to clone a slide and then use it within the same presentation file but at a different position, use the insertClone method:

  1. Create an instance of the Presentation class.
  2. Instantiate the class by referencing the Slides collection exposed by the Presentation object.
  3. Call the insertClone method exposed by the ISlideCollection object and pass the slide to be cloned along with the index for the new position as a parameter to the insertClone method.
  4. Write the modified presentation as a PPTX file.

In the example given below, we have cloned a slide (lying at the zero index – position 1 – of the presentation) to index 1 – Position 2 – of the presentation.

  # Instantiate Presentation class that represents a presentation file
  $pres = new Presentation("CloneWithInSamePresentation.pptx");
  try {
    # Clone the desired slide to the end of the collection of slides in the same presentation
    $slds = $pres->getSlides();
    # Clone the desired slide to the specified index in the same presentation
    $slds->insertClone(2, $pres->getSlides()->get_Item(1));
    # Write the modified presentation to disk
    $pres->save("Aspose_CloneWithInSamePresentation_out.pptx", SaveFormat::Pptx);
  } finally {
    $pres->dispose();
  }

Clone at End in another Presentation

If you need to clone a slide from one presentation and use it in another presentation file, at the end of the existing slides:

  1. Create an instance of the Presentation class containing the presentation the slide will be cloned from.
  2. Create an instance of the Presentation class containing the destination presentation that the slide will be added to.
  3. Instantiate the ISlideCollection class by referencing the Slides collection exposed by the Presentation object of the destination presentation.
  4. Call the addClone method exposed by the ISlideCollection object and pass the slide from the source presentation as a parameter to the addClone method.
  5. Write the modified destination presentation file.

In the example given below, we have cloned a slide (from the first index of the source presentation) to the end of the destination presentation.

  # Instantiate Presentation class to load the source presentation file
  $srcPres = new Presentation("CloneAtEndOfAnother.pptx");
  try {
    # Instantiate Presentation class for destination PPTX (where slide is to be cloned)
    $destPres = new Presentation();
    try {
      # Clone the desired slide from the source presentation to the end of the collection of slides in destination presentation
      $slds = $destPres->getSlides();
      $slds->addClone($srcPres->getSlides()->get_Item(0));
      # Write the destination presentation to disk
      $destPres->save("Aspose2_out.pptx", SaveFormat::Pptx);
    } finally {
      $destPres->dispose();
    }
  } finally {
    $srcPres->dispose();
  }

Clone at Another Position in another Presentation

If you need to clone a slide from one presentation and use it in another presentation file, at a specific position:

  1. Create an instance of the Presentation class containing the source presentation the slide will be cloned from.
  2. Create an instance of the Presentation class containing the presentation the slide will be added to.
  3. Instantiate the ISlideCollection class by referencing the Slides collection exposed by the Presentation object of the destination presentation.
  4. Call the insertClone method exposed by the ISlideCollection object and pass the slide from the source presentation along with the desired position as a parameter to the insertClone method.
  5. Write the modified destination presentation file.

In the example given below, we have cloned a slide (from the zero index of the source presentation) to index 1 (position 2) of the destination presentation.

  # Instantiate Presentation class to load the source presentation file
  $srcPres = new Presentation("CloneAtEndOfAnother.pptx");
  try {
    # Instantiate Presentation class for destination PPTX (where slide is to be cloned)
    $destPres = new Presentation();
    try {
      # Clone the desired slide from the source presentation to the end of the collection of slides in destination presentation
      $slds = $destPres->getSlides();
      $slds->insertClone(2, $srcPres->getSlides()->get_Item(0));
      # Write the destination presentation to disk
      $destPres->save("Aspose2_out.pptx", SaveFormat::Pptx);
    } finally {
      $destPres->dispose();
    }
  } finally {
    $srcPres->dispose();
  }

Clone at specific position in another Presentation

If you need to clone a slide with a master slide from one presentation from and use it in another presentation, you need to clone the desired master slide from source presentation to destination presentation first. Then you need to use that master slide for cloning slide with master slide. The addClone(ISlide, IMasterSlide, boolean) expects a master slide from destination presentation rather than from source presentation. In order to clone the slide with a master, please follow the steps below:

  1. Create an instance of the Presentation class containing the source presentation the slide will be cloned from.
  2. Create an instance of the Presentation class containing the destination presentation the slide will be cloned to.
  3. Access the slide to be cloned along with the master slide.
  4. Instantiate the IMasterSlideCollection class by referencing the Masters collection exposed by the Presentation object of the destination presentation.
  5. Call the addClone method exposed by the IMasterSlideCollection object and pass the master from the source PPTX to be cloned as a parameter to the addClone method.
  6. Instantiate the ISlideCollection class by setting the reference to the Slides collection exposed by the Presentation object of the destination presentation.
  7. Call the addClone method exposed by the ISlideCollection object and pass the slide from the source presentation to be cloned and master slide as a parameter to the addClone method.
  8. Write the modified destination presentation file.

In the example given below, we have cloned a slide with a master (lying at the zero index of the source presentation) to the end of the destination presentation using a master from source slide.

  # Instantiate Presentation class to load the source presentation file
  $srcPres = new Presentation("CloneToAnotherPresentationWithMaster.pptx");
  try {
    # Instantiate Presentation class for destination presentation (where slide is to be cloned)
    $destPres = new Presentation();
    try {
      # Instantiate ISlide from the collection of slides in source presentation along with
      # Master slide
      $SourceSlide = $srcPres->getSlides()->get_Item(0);
      $SourceMaster = $SourceSlide->getLayoutSlide()->getMasterSlide();
      # Clone the desired master slide from the source presentation to the collection of masters in the
      # Destination presentation
      $masters = $destPres->getMasters();
      $DestMaster = $SourceSlide->getLayoutSlide()->getMasterSlide();
      # Clone the desired master slide from the source presentation to the collection of masters in the
      # Destination presentation
      $iSlide = $masters->addClone($SourceMaster);
      # Clone the desired slide from the source presentation with the desired master to the end of the
      # Collection of slides in the destination presentation
      $slds = $destPres->getSlides();
      $slds->addClone($SourceSlide, $iSlide, true);
      # Save the destination presentation to disk
      $destPres->save("CloneToAnotherPresentationWithMaster_out.pptx", SaveFormat::Pptx);
    } finally {
      $destPres->dispose();
    }
  } finally {
    $srcPres->dispose();
  }

Clone at End in Specified Section

If you want to clone a slide and then use it within the same presentation file but at a different section, then use the addClone method exposed by the ISlideCollection interface. Aspose.Slides for PHP via Java makes it possible to clone a slide from the first section and then insert that cloned slide to the second section of the same presentation.

The following code snippet shows you how to clone a slide and insert the cloned slide into a specified section.

  $presentation = new Presentation();
  try {
    $presentation->getSlides()->get_Item(0)->getShapes()->addAutoShape(ShapeType::Rectangle, 200, 50, 300, 100);
    $presentation->getSections()->addSection("Section 1", $presentation->getSlides()->get_Item(0));
    $section2 = $presentation->getSections()->appendEmptySection("Section 2");
    $presentation->getSlides()->addClone($presentation->getSlides()->get_Item(0), $section2);
    # Save the destination presentation to disk
    $presentation->save($dataDir . "CloneSlideIntoSpecifiedSection.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($presentation)) {
      $presentation->dispose();
    }
  }
