Split PowerPoint Presentations by Slides in Python

Developers can use Spire.Presentation for Python to split a PowerPoint presentation into individual slides by iterating through the slides in the presentation and adding each slide to a new presentation. The detailed steps are as follows.

• Create an instance of the Presentation class.
• Load a PowerPoint presentation using the Presentation.LoadFromFile() method.
• Iterate through all slides in the presentation:
  • Access the current slide through the Presentation.Slides[index] property.
  • Create a new PowerPoint presentation using the Presentation class and remove its default slide using the Presentation.Slides.RemoveAt(0) method.
  • Append the current slide to the new presentation using the Presentation.Slides.AppendBySlide() method.
  • Save the new presentation as a file using the ISlide.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create an instance of the Presentation class
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")

# Iterate through all slides in the presentation
for i in range(presentation.Slides.Count):
    # Get the current slide
    slide = presentation.Slides[i]
    
    # Create a new PowerPoint presentation and remove its default slide
    newPresentation = Presentation()
    newPresentation.Slides.RemoveAt(0)
    
    # Append the current slide to the new presentation
    newPresentation.Slides.AppendBySlide(slide)
    
    # Save the new presentation as a file
    newPresentation.SaveToFile(f"output/Presentations/Slide-{i + 1}.pptx", FileFormat.Pptx2013)    
    newPresentation.Dispose()

presentation.Dispose()

Split PowerPoint Presentations by Slide Ranges in Python

Apart from splitting a PowerPoint presentation into individual slides, developers can also divide it into specific ranges of slides by adding the desired slides to new presentations. The detailed steps are as follows.

• Create an instance of the Presentation class.
• Load a PowerPoint presentation using the Presentation.LoadFromFile() method.
• Create new PowerPoint presentations using the Presentation class and remove the default slides within them using the Presentation.Slides.RemoveAt(0) method.
• Append specified ranges of slides to the new presentations using the Presentation.Slides.AppendBySlide() method.
• Save the new presentations as files using the Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create an instance of the Presentation class
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")

# Create two new PowerPoint presentations and remove their default slides
presentation1 = Presentation()
presentation2 = Presentation()
presentation1.Slides.RemoveAt(0)
presentation2.Slides.RemoveAt(0)

# Append slides 1-3 to the first new presentation
for i in range(3):
    presentation1.Slides.AppendBySlide(presentation.Slides[i])
# Append the remaining slides to the second new presentation
for i in range(3, presentation.Slides.Count):
    presentation2.Slides.AppendBySlide(presentation.Slides[i])

# Save the new presentations as files
presentation1.SaveToFile("output/Presentations/SlideRange1.pptx", FileFormat.Pptx2013)
presentation2.SaveToFile("output/Presentations/SlideRange2.pptx", FileFormat.Pptx2013)

presentation1.Dispose()
presentation2.Dispose()
presentation.Dispose()

Split PowerPoint Presentations by Sections in Python

Sections in PowerPoint are often used to organize slides into manageable groups. With Spire.Presentation for Python, developers can split a PowerPoint presentation into sections by iterating through the sections in the presentation and adding the slides within each section to a new presentation. The detailed steps are as follows.

• Create an instance of the Presentation class.
• Load a PowerPoint presentation using the Presentation.LoadFromFile() method.
• Iterate through all sections in the presentation:
  • Access the current section through the Presentation.SectionList[] property.
  • Create a new PowerPoint presentation using the Presentation class and remove its default slide using the Presentation.Slides.RemoveAt(0) method.
  • Add a section to the new presentation with the same name using the Presentation.SectionList.Append() method.
  • Retrieve the slides of the current section using the Section.GetSlides() method.
  • Iterate through the retrieved slides and add them to the section of the new presentation using the Section.Insert() method.
  • Save the new presentation as a file using the Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create an instance of the Presentation class
presentation = Presentation()
# Load a PowerPoint presentation
presentation.LoadFromFile("Sample.pptx")

# Iterate through all sections
for i in range(presentation.SectionList.Count):
    # Get the current section
    section = presentation.SectionList[i]
    
    # Create a new PowerPoint presentation and remove its default slide
    newPresentation = Presentation()
    newPresentation.Slides.RemoveAt(0)
    # Add a section to the new presentation
    newSection = newPresentation.SectionList.Append(section.Name)
    
    # Retrieve the slides of the current section
    slides = section.GetSlides()
    
    # Insert each retrieved slide into the section of the new presentation
    for slide_index, slide in enumerate(slides):
        newSection.Insert(slide_index, slide)
    
    # Save the new presentation as a file
    newPresentation.SaveToFile(f"output/Presentations/Section-{i + 1}.pptx", FileFormat.Pptx2019)
    newPresentation.Dispose()

A well-chosen background can enhance a presentation's appeal, but overly elaborate colors or images may distract viewers and obscure the main message. Additionally, when reusing templates, the original background may not suit the new content. In these cases, removing the background becomes essential to keep your slides clear and focused. This article will show you how to remove backgrounds from PowerPoint slides or slide masters in Python with Spire.Presentation for Python, giving you the flexibility to create clean, professional presentations that keep the audience's attention on what matters.

• Remove Backgrounds from the Specified Slide
• Remove Backgrounds from All Slides
• Remove Backgrounds from PowerPoint Slide Masters

Install Spire.Presentation for Python

This scenario requires Spire.Presentation for Python and plum-dispatch v1.7.4. They can be easily installed in your Windows through the following pip command.

pip install Spire.Presentation

If you are unsure how to install, please refer to this tutorial: How to Install Spire.Presentation for Python on Windows

Remove Backgrounds from the Specified Slide

There are typically two types of backgrounds in PowerPoint: background colors and background images. Although these backgrounds differ in their setup, the method to clear them is the same - using the BackgroundType property provided by Spire.Presentation for Python. Let's take a closer look at how to remove backgrounds from a PowerPoint slide with it.

Steps to remove background from a specified slide:

• Create an object for the Presentation class.
• Load a PowerPoint presentation from the local storage using Presentation.LoadFromFile() method.
• Get a certain slide with Presentation.Slides[] method.
• Remove the background by configuring BackgroundType property to none.
• Save the modified PowerPoint presentation using Presentation.SaveToFile() method, and release the memory.

Here is the code example of removing the background on the fourth slide:

from spire.presentation import *

# Create a Presentation document object
presentation = Presentation()
# Read the presentation document from file
presentation.LoadFromFile("imagebackground.pptx")

# Get the fourth slide
slide = presentation.Slides[3]

# Remove the background by setting the background type
slide.SlideBackground.Type = BackgroundType.none

# Save the modified presentation
presentation.SaveToFile("RemoveBackground.pptx", FileFormat.Pptx2010)

# Release resource
presentation.Dispose()

Remove Backgrounds from All Slides

Batch-deleting all slide backgrounds follows nearly the same steps as deleting a single slide background. The main difference is that you'll need to loop through each slide before setting the background type to ensure no slides are missed.

Steps to remove backgrounds from PowerPoint slides in a batch:

• Instantiate a Presentation class.
• Specify the file path to read a PowerPoint presentation using Presentation.LoadFromFile() method.
• Loop through each slide in the presentation.
• Remove all backgournds by applying BackgroundType.none property to each slide.
• Save the updated PowerPoint presentation as a new file with Presentation.SaveToFile() method, and release the resource.

Below is the code example for removing each background from PowerPoint slides:

from spire.presentation import *

# Create a Presentation document object
presentation = Presentation()
# Read the presentation document from file
presentation.LoadFromFile("presentation.pptx")

# Loop through each slide
for slide in presentation.Slides:
    # Remove the background image or color by setting the background type
    slide.SlideBackground.Type = BackgroundType.none

# Save the modified presentation
presentation.SaveToFile("RemoveBackground_allSlides.pptx", FileFormat.Pptx2010)

# Release resource
presentation.Dispose()

How to Remove Backgrounds from PowerPoint Slide Masters

If the slide background still exists after using the above method, you may need to remove the slide master's background instead. Unlike individual slides, setting the background of a slide master applies changes across all slides, so removing the slide master background can efficiently clear all backgrounds at once.

Steps to remove backgrounds from PowerPoint slide masters:

• Create an instance of the Presentation class.
• Load a presentation from the disk with Presentation.LoadFromFile() method.
• Retrieve a specified slide master using Presentation.Masters[] method.
• Access the background of the slide master with Masters.SlideBackground property.
• Remove the background by setting BackgroundType property to none.
• Save the newly modified PowerPoint presentation with Presentation.SaveToFile() method.

Note: Since the process of batch-removing slide master backgrounds is almost similar to deleting background from a slide master, this section will show the steps in the code comments rather than listing them separately.

Here is an example of removing the background from the third slide master:

from spire.presentation import *


# Create a Presentation object
presentation = Presentation()

# Load the sample file from the disk
presentation.LoadFromFile("presentation.pptx")

# Get the third slide master
master = presentation.Masters[2]

# Access the background of the slide master
SlideBackground = master.SlideBackground

# Clear the background by setting the slide master background style to none
master.SlideBackground.Type = BackgroundType.none

# Loop through each slide master
#for master in presentation.Masters:
    # Set the background type to none to remove it
    #master.SlideBackground.Type = BackgroundType.none

# Save the result presentation
presentation.SaveToFile("remove_background.pptx", FileFormat.Pptx2013)

# Release resources
presentation.Dispose()

master1 = pres.Masters.AppendSlide(pres.Masters.get_Item(0))
coverMaster = pres.Masters.get_Item(master1)
master2 = pres.Masters.AppendSlide(pres.Masters.get_Item(0))
bodyMaster = pres.Masters.get_Item(master2)

# Set background images for the two slide masters
pic1 = "Background1.jpg"
pic2 = "Background2.jpg"

rect = RectangleF.FromLTRB (0, 0, pres.SlideSize.Size.Width, pres.SlideSize.Size.Height)
coverMaster.SlideBackground.Fill.FillType = FillFormatType.Picture
image1 = coverMaster.Shapes.AppendEmbedImageByPath (ShapeType.Rectangle, pic1, rect)
coverMaster.SlideBackground.Fill.PictureFill.Picture.EmbedImage = image1.PictureFill.Picture.EmbedImage

bodyMaster.SlideBackground.Fill.FillType = FillFormatType.Picture
image2 = bodyMaster.Shapes.AppendEmbedImageByPath (ShapeType.Rectangle, pic2, rect)
bodyMaster.SlideBackground.Fill.PictureFill.Picture.EmbedImage = image2.PictureFill.Picture.EmbedImage

# Insert a logo to the body slide master
logo = "Logo.png"
bodyMaster.Shapes.AppendEmbedImageByPath(ShapeType.Rectangle, logo, RectangleF.FromLTRB(pres.SlideSize.Size.Width - 110, 10, pres.SlideSize.Size.Width - 10, 110))

# Insert text to the body slide master
shape = bodyMaster.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB(pres.SlideSize.Size.Width - 210, 110, pres.SlideSize.Size.Width - 10, 150))
shape.Fill.FillType = FillFormatType.none
shape.Line.FillType = FillFormatType.none
shape.TextFrame.Text = "Spire.Presentation"

# Set the color scheme for the two slide masters
coverMaster.Theme.ColorScheme.Accent1.Color = Color.get_Red()
coverMaster.Theme.ColorScheme.Accent2.Color = Color.get_Blue()

bodyMaster.Theme.ColorScheme.Accent1.Color = Color.get_Brown()
coverMaster.Theme.ColorScheme.Accent2.Color = Color.get_Green()

# Apply the first master with layout to the first slide
pres.Slides.get_Item(0).Layout = coverMaster.Layouts.GetByType(SlideLayoutType.Title)

# Apply the second master with layout to other slides
for i in range(1, pres.Slides.Count):
    pres.Slides.get_Item(i).Layout = bodyMaster.Layouts.GetByType(SlideLayoutType.TitleAndObject)

# Save the document

pres.LoadFromFile("output/CreateAndApplySlideMaster.pptx")

# Get the third slide master
master = pres.Masters[2]

# Change the background
master.SlideBackground.Type = BackgroundType.Custom
master.SlideBackground.Fill.FillType = FillFormatType.Solid
master.SlideBackground.Fill.SolidColor.Color = Color.get_LightBlue()

# Change the color sheme
master.Theme.ColorScheme.Accent1.Color = Color.get_Red()
master.Theme.ColorScheme.Accent2.Color = Color.get_Green()

# Remove the pictures in the slide master
pictures = [shape for shape in master.Shapes if isinstance(shape, SlidePicture)]
for picture in pictures:
    master.Shapes.Remove(picture)

# Change the text in the slide master
texts = [shape for shape in master.Shapes if isinstance(shape, IAutoShape)]
for text in texts:
    if len(text.TextFrame.Text) != 0:
        text.TextFrame.Text = "Spire.Presentation for Python"

# Save the presentation
pres.SaveToFile("output/ModifySlideMaster.pptx", FileFormat.Pptx2016)
pres.Dispose()

Copy Slide Masters Between PowerPoint Presentations

Applying the slide style of a presentation to another presentation can be achieved by copying the slide master between presentations and applying the master style to the specified slides. The following are the steps to copy the slide master between presentations and apply it to the specified slides:

• Create two objects of Presentation class and load two presentation documents using Presentation.LoadFromFile() method.
• Get the slide master of the second presentation using Presentation.Masters.get_Item() method.

       # If it is a footer placeholder
       if type == PlaceholderType.Footer:
           # Convert the shape to IAutoShape type
            autoShape = shape if isinstance(shape, IAutoShape) else None
            if autoShape is not None:
                # Set the text content to "E-ICEBLUE"
                autoShape.TextFrame.Text = "E-ICEBLUE"

       # If it is a slide number placeholder
       if type == PlaceholderType.SlideNumber:
            # Convert the shape to IAutoShape type
            autoShape = shape if isinstance(shape, IAutoShape) else None
            if autoShape is not None:
                # Modify the text font
                change_font(autoShape.TextFrame.Paragraphs[0])

# Save the modified presentation to a file
presentation.SaveToFile("ModifiedFooter.pptx", FileFormat.Pptx2016)

# Release the resources of the Presentation object
presentation.Dispose()

Python Remove Footers in PowerPoint Documents

To delete footers in a PowerPoint document, you first need to locate placeholders such as footers, page numbers, and time in the slides, and then remove them from the collection of shapes in the slide to ensure complete removal of footer content. Here are the detailed steps:

• Create a Presentation object.
• Load a PowerPoint document using the Presentation.LoadFromFile() method.
• Use the Presentation.Slides[index] property to retrieve a slide.
• Iterate through the shapes in the slide using a for loop, check if they are placeholders, and if they are footer placeholders, page number placeholders, or time placeholders, remove them from the slide.
• Save the document using the Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load a presentation from a file
presentation.LoadFromFile("Sample2.pptx")

# Get the first slide
slide = presentation.Slides[0]

# Iterate through the shapes on the slide
for i in range(len(slide.Shapes) - 1, -1, -1):
    # Check if the shape is a placeholder
    if slide.Shapes[i].Placeholder is not None:
        # Get the placeholder type
        type = slide.Shapes[i].Placeholder.Type

        # If it is a footer placeholder
        if type == PlaceholderType.Footer:
            # Remove it from the slide
            slide.Shapes.RemoveAt(i)

        # If it is a slide number placeholder
        if type == PlaceholderType.SlideNumber:
            # Remove it from the slide
            slide.Shapes.RemoveAt(i)

        # If it is a date and time placeholder
        if type == PlaceholderType.DateAndTime:
            # Remove it from the slide
            slide.Shapes.RemoveAt(i)

# Save the modified presentation to a file
presentation.SaveToFile("RemovedFooter.pptx", FileFormat.Pptx2016)

# Release the resources of the Presentation object
presentation.Dispose()

from spire.presentation.common import *

# Create two instances of Presentation class
pres1 = Presentation()
pres2 = Presentation()

# Load two presentation files
pres1.LoadFromFile("Sample1.pptx")
pres2.LoadFromFile("Sample2.pptx")

# Iterate through the slides of the second presentation
for slide in pres2.Slides:
    # Add each slides to the first presentation and keep the original design
    pres1.Slides.AppendBySlide(slide)

# Save the first presentation
pres1.SaveToFile("output/MergePresentations.pptx", FileFormat.Pptx2016)
pres1.Dispose()
pres2.Dispose()

Merging PowerPoint Presentations with Consistent Design

Developers can also use Presentation.Slides.AppendByMaster(slide Islide, master IMasterSlide) method to insert slides into the target presentation and change the design of the slides to the design of the target presentation. This allows for merging presentations and ensuring a consistent design.

The detailed stops are as follows:

• Create two instances of Presentation class.
• Load two PowerPoint presentations using Presentation.LoadFromFile() method.
• Iterate through each slide in the second presentation and add them to the first presentation while changing their design to the design of the first presentation using Presentation.Slides.AppendByMaster() method.
• Save the first presentation using Presentation.SaveToFile() method.

Prerequisite Knowledge

Document properties can be divided into two types: standard document properties and custom document properties.

• Standard document properties are pre-defined properties that are commonly used across various PowerPoint presentations. Some examples of standard document properties include title, author, subject, keywords and company. Standard document properties are useful for providing general information and metadata about the presentation.
• Custom document properties are user-defined properties that allow you to add specific information to a PowerPoint presentation. Unlike standard document properties, custom properties are not predefined and can be tailored to suit your specific needs. Custom properties usually provide information relevant to your presentation that may not be covered by the default properties.

Spire.Presentation for Python offers the DocumentProperty class to work with both standard document properties and custom document properties. The standard document properties can be accessed using the properties like Title, Subject, Author, Manager, Company, etc. of the DocumentProperty class. To add or retrieve custom properties, you can use the set_Item() method and the GetPropertyName() method of the DocumentProperty class.

Add Document Properties to a PowerPoint File in Python

To add or change the standard document properties, you can assign values to the DocumentProperty.Title proerpty, DocumentProperty.Subject property and other similar properties. To add custom properties to a presentation, use the DocumentProperty.set_Item(name: str, value: SpireObject) method. The detailed steps are as follows.

• Create a Presentation object.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get the DocumentProperty object.
• Add standard document properties to the presentation by assigning values to the Title, Subject, Author, Manager, Company and Keywords properties of the object.
• Add custom properties to the presentation using set_Item() of the object.
• Save the presentation to a PPTX file using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load a PowerPoint document
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx")

# Get the DocumentProperty object
documentProperty = presentation.DocumentProperty

# Set built-in document properties
documentProperty.Title = "Annual Sales Presentation"
documentProperty.Subject = "Company performance and sales strategy"
documentProperty.Author = "John Smith"
documentProperty.Manager = "Sarah Johnson"
documentProperty.Company = "E-iceblue Corporation"
documentProperty.Category = "Business"
documentProperty.Keywords = "sales, strategy, performance"
documentProperty.Comments = "Please review and provide feedback by Friday"

# Add custom document properties
documentProperty.set_Item("Document ID", Int32(12))
documentProperty.set_Item("Authorized by", String("Product Manager"))
documentProperty.set_Item("Authorized Date", DateTime(2024, 1, 10, 0, 0, 0, 0))

# Save to file
presentation.SaveToFile("output/Properties.pptx", FileFormat.Pptx2019)
presentation.Dispose()

Read Document Properties of a PowerPoint File in Python

The DocumentProperty.Title and the similar properties are not only used to set standard properties but can return the values of standard properties as well. Since the name of a custom property is not constant, we need to get the name using the DocumentProperty.GetPropertyName(index: int) method. And then, we're able to get the property's value using the DocumentProperty.get_Item(name: str) method.

The steps to read document properties of a PowerPoint file are as follows.

• Create a Presentation object.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get the DocumentProperty object.
• Get the standard document properties by using the Title, Subject, Author, Manager, Company, and Keywords properties of the object.
• Get the count of the custom properties, and iterate through the custom properties.
• Get the name of a specific custom property by its index using DocumentProperty.GetPropertyName() method.
• Get the value of the property using DocumentProperty.get_Item() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load a PowerPoint document
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Properties.pptx")

# Get the DocumentProperty object
documentProperty = presentation.DocumentProperty

# Get the built-in document properties
print("Title: " + documentProperty.Title)
print("Subject: " + documentProperty.Subject)
print("Author: " + documentProperty.Author)
print("Manager : " + documentProperty.Manager)
print("Company: " + documentProperty.Company)
print("Category: " + documentProperty.Category)
print("Keywords: " + documentProperty.Keywords)
print("Comments: " + documentProperty.Comments)

# Get the count of the custom document properties
count = documentProperty.Count

# Iterate through the custom properties
for i in range(count):

    # Get the name of a specific custom property
    customPropertyName = documentProperty.GetPropertyName(i)

    # Get the value of the custom property
    customPropertyValue = documentProperty.get_Item(customPropertyName)

    # Print the result
    print(customPropertyName + ": " + str(customPropertyValue))

Remove Document Properties from a PowerPoint File in Python

Removing a standard property means assigning an empty string to a property like DocumentProperty.Title. To remove the custom properties, Spire.Presentation provides the DocumentProperty.Remove(name: str) method. The following are the steps to remove document properties from a PowerPoint file in Python.

• Create a Presentation object.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get the DocumentProperty object.
• Set the Title, Subject, Author, Manager, Company, and Keywords properties of the object to empty strings.
• Get the count of the custom properties.
• Get the name of a specific custom property by its index using DocumentProperty.GetPropertyName() method.
• Remove the custom property using DocumentProperty.Remove() method.
• Save the presentation to a PPTX file using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load a PowerPoint document
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Properties.pptx")

# Get the DocumentProperty object
documentProperty = presentation.DocumentProperty

# Set built-in document properties to empty strings
documentProperty.Title = ""
documentProperty.Subject = ""
documentProperty.Author = ""
documentProperty.Manager = ""
documentProperty.Company = ""
documentProperty.Category = ""
documentProperty.Keywords = ""
documentProperty.Comments = ""

# Get the count of the custom document properties
i = documentProperty.Count
while i > 0:

    # Get the name of a specific custom property
    customPropertyName = documentProperty.GetPropertyName(i - 1)

    # Remove the custom property
    documentProperty.Remove(customPropertyName)
    i = i - 1

# Save the presentation to a different pptx file
presentation.SaveToFile("Output/RemoveProperties.pptx",FileFormat.Pptx2019)
