A table is a structured way of organizing and presenting data in rows and columns. It usually consists of horizontal rows and vertical columns, and each intersection can contain text, numbers, or other types of data. By inserting a table into a presentation, users can create or display structured data on slides to make the content more organized. In addition, compared to text forms, tabular data can be more intuitive to show the differences between data, which helps readers understand more, thus enhancing the professionalism and readability of the presentation. This article is going to show how to use Spire.Presentation for Python to create or edit a table in a PowerPoint Presentation in Python programs.

Grouping shapes in PowerPoint can greatly simplify the shape editing process, especially when dealing with complex arrangements of shapes. It allows you to modify the entire group collectively, saving time and effort compared to adjusting each shape individually. This is particularly beneficial when you need to apply consistent formatting or positioning to a set of shapes. Ungrouping shapes provides increased flexibility and customization options. By ungrouping a set of grouped shapes, you regain individual control over each shape. This allows you to make specific modifications, resize or reposition individual shapes, and apply unique formatting or styling as needed. In this article, we will explain how to group and ungroup shapes in PowerPoint in Python using Spire.Presentation for Python.

Group Shapes in PowerPoint in Python

Spire.Presentation for Python provides the ISlide.GroupShapes(shapeList: List) method to group two or more shapes on a specific slide. The detailed steps are as follows.

• Create an object of the Presentation class.
• Get the first slide using Presentation.Slides[0] property.
• Add two shapes to the slide using ISlide.Shapes.AppendShape() method.
• Create a list to store the shapes that need to be grouped.
• Add the two shapes to the list.
• Group the two shapes using ISlide.GroupShapes(shapeList: List) method.
• Save the result document using Presentation.SaveToFile() method.

from spire.presentation import *

# Create an object of the Presentation class
ppt = Presentation()
# Get the first slide
slide = ppt.Slides[0]

# Add two shapes to the slide
rectangle = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB (250, 180, 450, 220))
rectangle.Fill.FillType = FillFormatType.Solid
rectangle.Fill.SolidColor.KnownColor = KnownColors.SkyBlue

rectangle.Line.Width = 0.1
ribbon = slide.Shapes.AppendShape(ShapeType.Ribbon2, RectangleF.FromLTRB (290, 155, 410, 235))
ribbon.Fill.FillType = FillFormatType.Solid
ribbon.Fill.SolidColor.KnownColor = KnownColors.LightPink
ribbon.Line.Width = 0.1

# Add the two shapes to a list
shape_list = []
shape_list.append(rectangle)
shape_list.append(ribbon)

# Group the two shapes
slide.GroupShapes(shape_list)

# Save the resulting document
ppt.SaveToFile("GroupShapes.pptx", FileFormat.Pptx2013)
ppt.Dispose()

Ungroup Shapes in PowerPoint in Python

To ungroup the grouped shapes in a PowerPoint document, you need to iterate through all slides in the document and all shapes on each slide, find the grouped shapes and then ungroup them using ISlide.Ungroup(groupShape: GroupShape) method. The detailed steps are as follows.

• Create an object of the Presentation class.
• Load the PowerPoint document using Presentation.LoadFromFile() method.
• Iterate through all slides in the document.
• Iterate through all shapes on each slide.
• Check if the current shape is of GroupShape type. If the result is True, ungroup it using ISlide.Ungroup(groupShape: GroupShape) method.
• Save the result document using Presentation.SaveToFile() method.

from spire.presentation import *

# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint document
ppt.LoadFromFile("GroupShapes.pptx")

# Iterate through all slides in the document
for i in range(ppt.Slides.Count):
    slide = ppt.Slides[i]
    
    # Iterate through all shapes on each slide
    for j in range(slide.Shapes.Count):
        shape = slide.Shapes[j]
        
        # Check if the shape is a grouped shape
        if isinstance(shape, GroupShape):
            groupShape = shape            
            # Ungroup the grouped shape
            slide.Ungroup(groupShape)

# Save the resulting document
ppt.SaveToFile("UngroupShapes.pptx", FileFormat.Pptx2013)
ppt.Dispose()

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.common import *
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()
