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.

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()

• Get the first page of the document using PdfDocument.Pages.get_Item() method.
• Define a rectangular area.
• Find all occurrences of specific text in the specified rectangular area on the first page using PdfPageBase.FindText() method.
• Loop through the occurrences and apply a highlight color to each occurrence using ApplyHighLight() method.
• Save the document using PdfDocument.SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *

# Create an objetc of PdfDocument and load a PDF document
pdf = PdfDocument()
pdf.LoadFromFile("Sample.pdf")

# Get a page
pdfPageBase = pdf.Pages.get_Item(0)

# Define a rectangular area
rctg = RectangleF(0.0, 0.0, pdfPageBase.ActualSize.Width, 300.0)

# Find all the occurrences of specified text in the rectangular area
findCollection = pdfPageBase.FindText(rctg,"cloud server",TextFindParameter.IgnoreCase)

# Find text in the rectangle
for find in findCollection.Finds:
        #Highlight searched text
        find.ApplyHighLight(Color.get_Green())

# Save the document
pdf.SaveToFile("output/FindHighlightArea.pdf")
pdf.Close()

Find and Highlight Text in PDF using Regular Expression with Python

Sometimes the text that needs to be highlighted is not exactly the same words. In this case, the use of regular expressions allows more flexibility in text search. By passing TextFindParameter.Regex as parameter to the PdfPageBase.FindText() method, we can find text using regular expression in PDF documents. The detailed steps are as follows:

• Create an object of PdfDocument class and load a PDF document using PdfDocument.LoadFromFile() method.
• Specify the regular expression.
• Get a page using PdfDocument.Pages.get_Item() method.
• Find matched text with the regular expression on the page using PdfPageBase.FindText() method.
• Loop through the matched text and apply Highlight color to the text using ApplyHighLight() method.
• Save the document using PdfDocument.SaveToFile() method.

from spire.pdf import *
from spire.pdf.common import*

# Create an object of PdfDocument class and load a PDF document
pdf = PdfDocument()
pdf.LoadFromFile("Sample.pdf")

# Specify the regular expression that matches two words after *
regex = "\\*(\\w+\\s+\\w+)"

# Get the second page
page = pdf.Pages.get_Item(1)

# Find matched text on the page using regular expression
result = page.FindText(regex, TextFindParameter.Regex)

# Highlight the matched text
for text in result.Finds:
    text.ApplyHighLight(Color.get_DeepPink())

# Save the document
pdf.SaveToFile("output/FindHighlightRegex.pdf")
