Manage Zoom

Overview

Zooms in PowerPoint allow you to jump to and from specific slides, sections, and portions of a presentation. When you are presenting, this ability to navigate quickly across content might prove very useful.

overview_image

  • To summarize an entire presentation on a single slide, use a Summary Zoom.
  • To show selected slides only, use a Slide Zoom.
  • To show a single section only, use a Section Zoom.

Slide Zoom

A slide zoom can make your presentation more dynamic, allowing you to navigate freely between slides in any order you choose without interrupting the flow of your presentation. Slide zooms are great for short presentations without many sections, but you can still use them in different presentation scenarios.

Slide zooms help you drill into multiple pieces of information while you feel like you are on a single canvas.

For slide zoom objects, Aspose.Slides provides the ZoomImageType enumeration, the IZoomFrame interface, and some methods under the IShapeCollection interface.

Creating Zoom Frames

You can add a zoom frame on a slide this way:

  1. Create an instance of the Presentation class.
  2. Create new slides to which you intend to link the zoom frames.
  3. Add an identification text and background to the created slides.
  4. Add zoom frames (containing the references to created slides) to the first slide.
  5. Write the modified presentation as a PPTX file.

This PHP code shows you how to create a zoom frame on a slide:

  $pres = new Presentation();
  try {
    # Adds new slides to the presentation
    $slide2 = $pres->getSlides()->addEmptySlide($pres->getSlides()->get_Item(0)->getLayoutSlide());
    $slide3 = $pres->getSlides()->addEmptySlide($pres->getSlides()->get_Item(0)->getLayoutSlide());
    # Creates a background for the second slide
    $slide2->getBackground()->setType(BackgroundType::OwnBackground);
    $slide2->getBackground()->getFillFormat()->setFillType(FillType::Solid);
    $slide2->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->cyan);
    # Creates a text box for the second slide
    $autoshape = $slide2->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 200, 500, 200);
    $autoshape->getTextFrame()->setText("Second Slide");
    # Creates a background for the third slide
    $slide3->getBackground()->setType(BackgroundType::OwnBackground);
    $slide3->getBackground()->getFillFormat()->setFillType(FillType::Solid);
    $slide3->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->darkGray);
    # Create a text box for the third slide
    $autoshape = $slide3->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 200, 500, 200);
    $autoshape->getTextFrame()->setText("Trird Slide");
    # Adds ZoomFrame objects
    $pres->getSlides()->get_Item(0)->getShapes()->addZoomFrame(20, 20, 250, 200, $slide2);
    $pres->getSlides()->get_Item(0)->getShapes()->addZoomFrame(200, 250, 250, 200, $slide3);
    # Saves the presentation
    $pres->save("presentation.pptx", SaveFormat::Pptx);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Creating Zoom Frames with Custom Images

With Aspose.Slides for PHP via Java, you can create a zoom frame with a different slide preview image this way:

  1. Create an instance of the Presentation class.
  2. Create a new slide to which you intend to link the zoom frame.
  3. Add an identification text and background to the slide.
  4. Create an IPPImage object by adding an image to the Images collection associated with the Presentation object that will be used to fill the frame.
  5. Add zoom frames (containing the reference to created slide) to the first slide.
  6. Write the modified presentation as a PPTX file.

This PHP code shows you how to create a zoom frame with a different image:

  $pres = new Presentation();
  try {
    # Adds a new slide to the presentation
    $slide = $pres->getSlides()->addEmptySlide($pres->getSlides()->get_Item(0)->getLayoutSlide());
    # Creates a background for the second slide
    $slide->getBackground()->setType(BackgroundType::OwnBackground);
    $slide->getBackground()->getFillFormat()->setFillType(FillType::Solid);
    $slide->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->cyan);
    # Creates a text box for the third slide
    $autoshape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 200, 500, 200);
    $autoshape->getTextFrame()->setText("Second Slide");
    # Creates a new image for the zoom object
    $picture;
    $image = Images->fromFile("image.png");
    try {
      $picture = $pres->getImages()->addImage($image);
    } finally {
      if (!java_is_null($image)) {
        $image->dispose();
      }
    }
    # Adds the ZoomFrame object
    $pres->getSlides()->get_Item(0)->getShapes()->addZoomFrame(20, 20, 300, 200, $slide, $picture);
    # Saves the presentation
    $pres->save("presentation.pptx", SaveFormat::Pptx);
  } catch (JavaException $e) {
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Formatting Zoom Frames

In the previous sections, we showed you how to create simple zoom frames. To create more complicated zoom frames, you have to alter a simple frame’s formatting. There are several formatting options you can apply to a zoom frame.

You can control a zoom frame’s formatting on a slide this way:

  1. Create an instance of the Presentation class.
  2. Create new slides to link to which you intend to link the zoom frame.
  3. Add some identification text and background to the created slides.
  4. Add zoom frames (containing the references to the created slides) to the first slide.
  5. Create an IPPImage object by adding an image to the Images collection associated with the Presentation object that will be used to fill the frame.
  6. Set a custom image for the first zoom frame object.
  7. Change the line format for the second zoom frame object.
  8. Remove the background from an image of the second zoom frame object.
  9. Write the modified presentation as a PPTX file.

This PHP code shows you how to change a zoom frame’s formatting on a slide:

  $pres = new Presentation();
  try {
    # Adds new slides to the presentation
    $slide2 = $pres->getSlides()->addEmptySlide($pres->getSlides()->get_Item(0)->getLayoutSlide());
    $slide3 = $pres->getSlides()->addEmptySlide($pres->getSlides()->get_Item(0)->getLayoutSlide());
    # Creates a background for the second slide
    $slide2->getBackground()->setType(BackgroundType::OwnBackground);
    $slide2->getBackground()->getFillFormat()->setFillType(FillType::Solid);
    $slide2->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->cyan);
    # Creates a text box for the second slide
    $autoshape = $slide2->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 200, 500, 200);
    $autoshape->getTextFrame()->setText("Second Slide");
    # Creates a background for the third slide
    $slide3->getBackground()->setType(BackgroundType::OwnBackground);
    $slide3->getBackground()->getFillFormat()->setFillType(FillType::Solid);
    $slide3->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->darkGray);
    # Creates a text box for the third slide
    $autoshape = $slide3->getShapes()->addAutoShape(ShapeType::Rectangle, 100, 200, 500, 200);
    $autoshape->getTextFrame()->setText("Trird Slide");
    # Adds ZoomFrame objects
    $zoomFrame1 = $pres->getSlides()->get_Item(0)->getShapes()->addZoomFrame(20, 20, 250, 200, $slide2);
    $zoomFrame2 = $pres->getSlides()->get_Item(0)->getShapes()->addZoomFrame(200, 250, 250, 200, $slide3);
    # Creates a new image for the zoom object
    $picture;
    $image = Images->fromFile("image.png");
    try {
      $picture = $pres->getImages()->addImage($image);
    } finally {
      if (!java_is_null($image)) {
        $image->dispose();
      }
    }
    # Sets custom image for zoomFrame1 object
    $zoomFrame1->setImage($picture);
    # Sets a zoom frame format for the zoomFrame2 object
    $zoomFrame2->getLineFormat()->setWidth(5);
    $zoomFrame2->getLineFormat()->getFillFormat()->setFillType(FillType::Solid);
    $zoomFrame2->getLineFormat()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->pink);
    $zoomFrame2->getLineFormat()->setDashStyle(LineDashStyle->DashDot);
    # Setting for Do not show background for zoomFrame2 object
    $zoomFrame2->setShowBackground(false);
    # Saves the presentation
    $pres->save("presentation.pptx", SaveFormat::Pptx);
  } catch (JavaException $e) {
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

Section Zoom

A section zoom is a link to a section in your presentation. You can use section zooms to go back to sections you want to really emphasize. Or you can use them to highlight how certain pieces of your presentation connect.

overview_image

For section zoom objects, Aspose.Slides provides the ISectionZoomFrame interface and some methods under the IShapeCollection interface.

Creating Section Zoom Frames

You can add a section zoom frame to a slide this way:

  1. Create an instance of the Presentation class.
  2. Create a new slide.
  3. Add an identification background to the created slide.
  4. Create a new section to which you intend to link the zoom frame.
  5. Add a section zoom frame (containing references to the created section) to the first slide.
  6. Write the modified presentation as a PPTX file.

    # Adds a new slide to the presentation
    $slide = $pres->getSlides()->addEmptySlide($pres->getSlides()->get_Item(0)->getLayoutSlide());
    $slide->getBackground()->getFillFormat()->setFillType(FillType::Solid);
    $slide->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->yellow);
    $slide->getBackground()->setType(BackgroundType::OwnBackground);
    # Adds a new Section to the presentation
    $pres->getSections()->addSection("Section 1", $slide);
    # Adds a SectionZoomFrame object
    $sectionZoomFrame = $pres->getSlides()->get_Item(0)->getShapes()->addSectionZoomFrame(20, 20, 300, 200, $pres->getSections()->get_Item(1));
    # Saves the presentation
    $pres->save("presentation.pptx", SaveFormat::Pptx);

Summary Zoom

A summary zoom is like a landing page where all the pieces of your presentation are displayed at once. When you’re presenting, you can use the zoom to go from one place in your presentation to another in any order you like. You can get creative, skip ahead, or revisit pieces of your slide show without interrupting the flow of your presentation.

overview_image

For summary zoom objects, Aspose.Slides provides the ISummaryZoomFrame, ISummaryZoomSection, and ISummaryZoomSectionCollection interfaces and some methods under the IShapeCollection interface.

Creating Summary Zoom

You can add a summary zoom frame to a slide this way:

  1. Create an instance of the Presentation class.

Adding and Removing Summary Zoom Section

All sections in a summary zoom frame are represented by ISummaryZoomSection objects, which are stored in the ISummaryZoomSectionCollection object. You can add or remove a summary zoom section object through the ISummaryZoomSectionCollection interface this way:

  1. Create an instance of the Presentation class.
  2. Create new slides with identification background and new sections for created slides.
  3. Add a summary zoom frame into the first slide.
  4. Add a new slide and section to the presentation.
