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)

Add a Text Watermark to PowerPoint in Python

Unlike MS Word, PowerPoint does not have a built-in feature that allows to apply watermarks to each slide. However, you can add a shape with text or an image to mimic the watermark effect. A shape can be added to a slide using the ISlide.Shapes.AppendShape() method, and the text of the shape can be set through the IAutoShape.TextFrame.Text property. To prevent the shape from overlapping the existing content on the slide, you'd better send it to the bottom.

The following are the steps to add a text watermark to a slide using Spire.Presentation for Python.

• Create a Presentation object.
• Load a PowerPoint file using Presentation.LoadFromFile() method.
• Get a specific slide through Prentation.Slides[index] property.
• Add a shape to the slide using ISlide.Shapes.AppendShape() method.
• Add text to the shape through IAutoShape.TextFrame.Text property.
• Send the shape to back using IAutoShape.SetShapeArrange() method.
• Save the presentation to a PowerPoint file using Presentation.SaveToFile() method.

from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

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

# Define a rectangle
left = (presentation.SlideSize.Size.Width - 350.0) / 2
top = (presentation.SlideSize.Size.Height - 110.0) / 2
rect = RectangleF(left, top, 350.0, 110.0)

for i in range(0, presentation.Slides.Count):

    # Add a rectangle shape to
    shape = presentation.Slides[i].Shapes.AppendShape(
    ShapeType.Rectangle, rect)
    
    # Set the style of the shape
    shape.Fill.FillType = FillFormatType.none
    shape.ShapeStyle.LineColor.Color = Color.get_Transparent()
    shape.Rotation = -35
    shape.Locking.SelectionProtection = True
    shape.Line.FillType = FillFormatType.none

    # Add text to the shape
    shape.TextFrame.Text = "CONFIDENTIAL"
    textRange = shape.TextFrame.TextRange

    # Set the style of the text range
    textRange.Fill.FillType = FillFormatType.Solid
    textRange.Fill.SolidColor.Color = Color.FromArgb(120, Color.get_Black().R, Color.get_HotPink().G, Color.get_HotPink().B)
    textRange.FontHeight = 45
    textRange.LatinFont = TextFont("Times New Roman")

    # Send the shape to back
    shape.SetShapeArrange(ShapeArrange.SendToBack)

# Save to file
presentation.SaveToFile("output/TextWatermark.pptx", FileFormat.Pptx2010)
presentation.Dispose()

Add an Image Watermark to PowerPoint in Python

To add an image watermark, you need first to create a rectangle with the same size as an image. Then fill the shape with this image and place the shape at the center of a slide. To prevent the shape from overlapping the existing content on the slide, you need to send it to the bottom as well. The following are the steps to add an image watermark to a slide using Spire.Presentation for Python.

• Create a Presentation object.
• Load a PowerPoint file using Presentation.LoadFromFile() method.
• Get a specific slide through Prentation.Slides[index] property.
• Load an image using Presentation.Images.AppendStream() method.
• Add a shape that has the same size with the image to the slide using ISlide.Shapes.AppendShape() method.
• Fill the shape with the image through IAuotShape.Fill.PictureFill.Picture.EmbedImage property.
• Send the shape to back using IAutoShape.SetShapeArrange() method.
• Save the presentation to a PowerPoint file using Presentation.SaveToFile() method.

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

# Create a Presentation object
presentation = Presentation()

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

# Load an image
stream = Stream("C:/Users/Administrator/Desktop/logo.png")
image = presentation.Images.AppendStream(stream)
stream.Close()

# Get width and height of the image
width = (float)(image.Width)
height = (float)(image.Height)

# 
slideSize = presentation.SlideSize.Size

# Loop through the slides in the presentation
for i in range(0, presentation.Slides.Count):

    # Get a specific slide
    slide = presentation.Slides[i]

    # Add a shape to slide
    shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF((slideSize.Width - width )/2, (slideSize.Height - height)/2, width, height))

    # Fill the shape with image
    shape.Line.FillType = FillFormatType.none
    shape.Locking.SelectionProtection = True
    shape.Fill.FillType =  FillFormatType.Picture
    shape.Fill.PictureFill.FillType = PictureFillType.Stretch
    shape.Fill.PictureFill.Picture.EmbedImage = image

    # Send the shape to back
    shape.SetShapeArrange(ShapeArrange.SendToBack)

# Save to file
presentation.SaveToFile("output/ImageWatermark.pptx", FileFormat.Pptx2013)
presentation.Dispose()
