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

  • 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.

slidezoomsel

For slide zoom objects, Aspose.Slides provides the ZoomImageType enumeration, the IZoomFrame interface, and some methods in 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.
  3. Add an identification text and background to the created slides.
  4. Add zoom frames (containing the references to created slides) into the first slide.
  5. Write the modified presentation as a PPTX file.

This sample code shows you how to create a zoom frame in a slide:

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    #Add new slides to the presentation
    slide2 = pres.slides.add_empty_slide(pres.slides[0].layout_slide)
    slide3 = pres.slides.add_empty_slide(pres.slides[0].layout_slide)

    # Create a background for the second slide
    slide2.background.type = slides.BackgroundType.OWN_BACKGROUND
    slide2.background.fill_format.fill_type = slides.FillType.SOLID
    slide2.background.fill_format.solid_fill_color.color = draw.Color.cyan

    # Create a text box for the second slide
    autoshape = slide2.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 200, 500, 200)
    autoshape.text_frame.text = "Second Slide"

    # Create a background for the third slide
    slide3.background.type = slides.BackgroundType.OWN_BACKGROUND
    slide3.background.fill_format.fill_type = slides.FillType.SOLID
    slide3.background.fill_format.solid_fill_color.color = draw.Color.dark_khaki

    # Create a text box for the third slide
    autoshape = slide3.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 200, 500, 200)
    autoshape.text_frame.text = "Trird Slide"

    #Add ZoomFrame objects
    pres.slides[0].shapes.add_zoom_frame(20, 20, 250, 200, slide2)
    pres.slides[0].shapes.add_zoom_frame(200, 250, 250, 200, slide3)

    # Save the presentation
    pres.save("presentation-zoom.pptx", slides.export.SaveFormat.PPTX)

Creating Zoom Frames with Custom Images

With Aspose.Slides for Python via .NET, you can create a zoom frame with an image other than the slide preview image this way:

  1. Create an instance of the Presentation class.
  2. Create a new slide to which you intend to link.
  3. Add an identification text and background to created 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) into the first slide.
  6. Write the modified presentation as a PPTX file.

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

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    #Add a new slide to the presentation
    slide = pres.slides.add_empty_slide(pres.slides[0].layout_slide)

    # Create a background for the second slide
    slide.background.type = slides.BackgroundType.OWN_BACKGROUND
    slide.background.fill_format.fill_type = slides.FillType.SOLID
    slide.background.fill_format.solid_fill_color.color = draw.Color.cyan

    # Create a text box for the third slide
    autoshape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 200, 500, 200)
    autoshape.text_frame.text = "Second Slide"

    # Create a new image for the zoom object
    image = pres.images.add_image(draw.Image.from_file("img.jpeg"))

    #Add the ZoomFrame object
    pres.slides[0].shapes.add_zoom_frame(20, 20, 300, 200, slide, image)

    # Save the presentation
    pres.save("presentation.pptx", slides.export.SaveFormat.PPTX)

Formatting Zoom Frames

In the previous sections (above), we showed you how to create simple zoom frames. To create more complicated zoom frames, you have to alter the frames' formatting. There are several formatting settings you can apply on a zoom frame.

You can control the formatting of a zoom frame in a slide this way:

  1. Create an instance of the Presentation class.
  2. Create new slides to link to.
  3. Add identification text and background to created slides.
  4. Add zoom frames (containing the references to created slides) into 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 python sample code shows you how to change the formatting of a zoom frame:

import aspose.slides as slides
import aspose.pydrawing as draw

with slides.Presentation() as pres:
    #Add new slides to presentation
    slide2 = pres.slides.add_empty_slide(pres.slides[0].layout_slide)
    slide3 = pres.slides.add_empty_slide(pres.slides[0].layout_slide)

    # Create a background for the second slide
    slide2.background.type = slides.BackgroundType.OWN_BACKGROUND
    slide2.background.fill_format.fill_type = slides.FillType.SOLID
    slide2.background.fill_format.solid_fill_color.color = draw.Color.cyan

    # Create a text box for the second slide
    autoshape = slide2.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 200, 500, 200)
    autoshape.text_frame.text = "Second Slide"

    # Create a background for the third slide
    slide3.background.type = slides.BackgroundType.OWN_BACKGROUND
    slide3.background.fill_format.fill_type = slides.FillType.SOLID
    slide3.background.fill_format.solid_fill_color.color = draw.Color.dark_khaki

    # Create a text box for the third slide
    autoshape = slide3.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 200, 500, 200)
    autoshape.text_frame.text = "Trird Slide"

    #Add ZoomFrame objects
    zoomFrame1 = pres.slides[0].shapes.add_zoom_frame(20, 20, 250, 200, slide2)
    zoomFrame2 = pres.slides[0].shapes.add_zoom_frame(200, 250, 250, 200, slide3)

    # Create a new image for the zoom object
    image = pres.images.add_image(draw.Image.from_file("img.jpeg"))
    # Set custom image for zoomFrame1 object
    zoomFrame1.image = image

    # Set a zoom frame format for the zoomFrame2 object
    zoomFrame2.line_format.width = 5
    zoomFrame2.line_format.fill_format.fill_type = slides.FillType.SOLID
    zoomFrame2.line_format.fill_format.solid_fill_color.color = draw.Color.hot_pink
    zoomFrame2.line_format.dash_style = slides.LineDashStyle.DASH_DOT

    # Do not show background for zoomFrame2 object
    zoomFrame2.show_background = False

    # Save the presentation
    pres.save("presentation-zoom2.pptx", slides.export.SaveFormat.PPTX)

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.

    # Saves the presentation
    pres.save("presentation.pptx", slides.export.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.

For summary zoom objects, Aspose.Slides provides the ISummaryZoomFrame, ISummaryZoomFrameSection, 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.
  2. Create new slides with identification background and new sections for created slides.
  3. Add the summary zoom frame to the first slide.
  4. Write the modified presentation as a PPTX file.

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

import aspose.slides as slides

    slide.background.fill_format.fill_type = slides.FillType.SOLID
    slide.background.fill_format.solid_fill_color.color = draw.Color.aqua
    slide.background.type = slides.BackgroundType.OWN_BACKGROUND

    # Adds a new section to the presentation
    pres.sections.add_section("Section 2", slide)

    # Adds SummaryZoomFrame object
    summaryZoomFrame = pres.slides[0].shapes.add_summary_zoom_frame(150, 50, 300, 200)

    #Adds a new slide to the presentation
    slide = pres.slides.add_empty_slide(pres.slides[0].layout_slide)
    slide.background.fill_format.fill_type = slides.FillType.SOLID
    slide.background.fill_format.solid_fill_color.color = draw.Color.chartreuse
    slide.background.type = slides.BackgroundType.OWN_BACKGROUND

    # Adds a new section to the presentation
    section3 = pres.sections.add_section("Section 3", slide)

    # Adds a section to the Summary Zoom
    summaryZoomFrame.summary_zoom_collection.add_summary_zoom_section(section3)

    # Removes section from the Summary Zoom
    summaryZoomFrame.summary_zoom_collection.remove_summary_zoom_section(pres.sections[1])
