Apply Shadow Effect to Text in PowerPoint in Python

Spire.Presentation for Python offers the InnerShadowEffect and OuterShadowEffect classes for creating inner and outer shadow effects. These shadow effects can then be applied to the text within shapes by using the IAutoShape.TextFrame.TextRange.EffectDag.InnerShadowEffect and IAutoShape.TextFrame.TextRange.EffectDag.OuterShadowEffect properties. The detailed steps are as follows.

• Create an object of the Presentation class.
• Get a specific slide in the presentation using the Presentation.Slides[index] property.
• Add a shape to the slide using the ISilde.Shapes.AppendShape() method.
• Add text to the shape using the IAutoShape.AppendTextFrame() method.
• Create an inner or outer shadow effect using the InnerShadowEffect or OuterShadowEffect class.
• Set the blur radius, direction, distance and color, for the inner or outer shadow effect using the properties offered by the InnerShadowEffect or OuterShadowEffect class.
• Apply the inner or outer shadow effect to the text within the shape using the IAutoShape.TextFrame.TextRange.EffectDag.InnerShadowEffect or IAutoShape.TextFrame.TextRange.EffectDag.OuterShadowEffect property.
• Save the resulting presentation using the Presentation.SaveToFile() method.

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

# Create an object of the Presentation class
ppt = Presentation()

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

# Add the first rectangular shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB(120, 60, 500, 200))
shape.Fill.FillType = FillFormatType.none

# Add text to the shape
shape.AppendTextFrame("Text With Outer Shadow Effect")
shape.TextFrame.Paragraphs[0].TextRanges[0].LatinFont = TextFont("Arial")
shape.TextFrame.Paragraphs[0].TextRanges[0].FontHeight = 21
shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.FillType = FillFormatType.Solid
shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.SolidColor.Color = Color.get_Black()

# Create an outer shadow effect
outerShadow = OuterShadowEffect()
# Set the blur radius, direction, distance and color for the outer shadow effect
outerShadow.BlurRadius = 0
outerShadow.Direction = 50
outerShadow.Distance = 10
outerShadow.ColorFormat.Color = Color.get_LightBlue()

# Apply the outer shadow effect to the text in the first rectangular shape
shape.TextFrame.TextRange.EffectDag.OuterShadowEffect = outerShadow

# Add the second rectangular shape to the slide
shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB(120, 300, 500, 440))
shape.Fill.FillType = FillFormatType.none

# Add text to the shape
shape.AppendTextFrame("Text With Inner Shadow Effect")
shape.TextFrame.Paragraphs[0].TextRanges[0].LatinFont = TextFont("Arial")
shape.TextFrame.Paragraphs[0].TextRanges[0].FontHeight = 21
shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.FillType = FillFormatType.Solid
shape.TextFrame.Paragraphs[0].TextRanges[0].Fill.SolidColor.Color = Color.get_Black()

# Create an inner shadow effect
innerShadow = InnerShadowEffect()
# Set the blur radius, direction, distance and color for the inner shadow effect
innerShadow.BlurRadius = 0
innerShadow.Direction = 50
innerShadow.Distance = 10
innerShadow.ColorFormat.Color = Color.get_LightBlue()

# Apply the inner shadow effect to the text in the second rectangular shape
shape.TextFrame.TextRange.EffectDag.InnerShadowEffect = innerShadow

Apply Transparent Effect to Text in PowerPoint in Python

Spire.Presentation for Python does not offer a direct method to apply transparency effect to text, but you can control the transparency by adjusting the alpha value of the text color. The detailed steps are as follows.

• Create an object of the Presentation class.
• Get a specific slide in the presentation using the Presentation.Slides[index] property.
• Add a shape to the slide using the ISilde.Shapes.AppendShape() method.
• Retrieve the paragraph collection from the text frame within the shape using the IAutoShape.TextFrame.Paragraphs property, then remove any default paragraphs from the collection using the ParagraphList.Clear() method.
• Add new paragraphs to the collection using the ParagraphList.Append() method, and insert text into each paragraph using the TextParagraph.TextRanges.Append() method.
• Set the fill type of the text to solid using the TextRange.Fill.FillType property.
• Adjust the transparency of the text by setting the color with varying alpha values using the Color.FromArgb(alpha:int, red:int, green:int, blue:int) method, where the alpha value controls the transparency level—the lower the alpha, the more transparent the text.
• Save the resulting presentation using the Presentation.SaveToFile() method.

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

# Create an object of the Presentation class
ppt = Presentation()

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

# Add a rectangular shape to the slide
textboxShape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB(100, 100, 400, 220))
# Make the border of the shape transparent
textboxShape.ShapeStyle.LineColor.Color = Color.get_Transparent()  
# Set the shape's fill to none
textboxShape.Fill.FillType = FillFormatType.none  

# Retrieve the paragraph collection from the text frame within the shape
paras = textboxShape.TextFrame.Paragraphs
# Remove any default paragraphs
paras.Clear()  

# Add three new paragraphs to the text frame, each with a different transparency level for the text
alpha = 55  # Initial alpha value for text transparency
for i in range(3):
    # Create and add a new paragraph
    paras.Append(TextParagraph())  
    # Add text to the paragraph
    paras[i].TextRanges.Append(TextRange("Text with Different Transparency"))  
    # Set the text fill type to solid
    paras[i].TextRanges[0].Fill.FillType = FillFormatType.Solid  
    # Set the text color with varying transparency, controlled by the alpha value
    paras[i].TextRanges[0].Fill.SolidColor.Color = Color.FromArgb(
        alpha,
        Color.get_Blue().R,
        Color.get_Blue().G,
        Color.get_Blue().B
    )
    # Increase alpha value to reduce transparency for the next paragraph
    alpha += 100  

# Save the resulting presentation
ppt.SaveToFile("SetTransparency.pptx", FileFormat.Pptx2013)
ppt.Dispose() 

Apply 3D Effect to Text in PowerPoint in Python

The FormatThreeD class in Spire.Presentation for Python is used for creating a 3D effect.

Modify Text in a Word Document in Python

In order to alter the content of a paragraph, the initial step is to obtain the desired paragraph from a specific section through the use of the Section.Paragraphs[index] property. Following this, you can replace the existing text with the new content by assigning it to the Paragraph.Text property of the chosen paragraph.

Here are the steps to edit text in a Word document with Python:

• Create a Document object.
• Load a Word file from the given file path.
• Get a specific section using Document.Sections[index] property.
• Get a specific paragraph using Section.Paragraphs[index] property.
• Reset the text of the paragraph using Paragraph.Text property.
• Save the updated document to a different Word file.

from spire.doc import *
from spire.doc.common import *

# Create a Document object
document = Document()

# Load an existing Word file
document.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");

# Get a specific section
section = document.Sections[0]

# Get a specific paragraph
paragraph = section.Paragraphs[0]

# Modify the text of the paragraph 
paragraph.Text = "The text has been modified"

# Save the document to a different Word file
document.SaveToFile("output/ModifyText.docx", FileFormat.Docx)

# Dispose resource
document.Dispose()

Change Formatting of Text in a Word Document in Python

To alter the text appearance of a particular paragraph, you first need to obtain the specified paragraph. Next, go through its child objects to find the individual text ranges. The formatting of each text range can then be updated using the TextRange.CharacterFormat property.

The steps to change text formatting in a Word document are as follows:

• Create a Document object.
• Load a Word file from the given file path.
• Get a specific section using Document.Sections[index] property.
• Get a specific paragraph using Section.Paragraphs[index] property.
• Iterate through the child objects in the paragraph.
  • Determine if a child object is a text range.
  • Get a specific text range.
  • Reset the text formatting using TextRange.CharacterFormat property.
• Save the updated document to a different Word file.

from spire.doc import *
from spire.doc.common import *

# Create an object of Document
doc = Document()

# Load a Word document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx")

# Get a specific section
section = document.Sections.get_Item(0)

# Get a specific paragraph
paragraph = section.Paragraphs.get_Item(0)

# Iterate through the child objects in the paragraph
for i in range(paragraph.ChildObjects.Count):
    
    # Determine if a child object is text range
    if isinstance(paragraph.ChildObjects[i], TextRange):

        # Get a specific text range
        textRange = paragraph.ChildObjects[i]

        # Reset font name
        textRange.CharacterFormat.FontName = "Corbel Light"

        # Reset font size
        textRange.CharacterFormat.FontSize = 11.0

        # Reset text color
        textRange.CharacterFormat.TextColor = Color.get_Blue()

        # Apply italic to the text range 
        textRange.CharacterFormat.Italic = True

# Save the document to a different Word file
doc.SaveToFile("output/ChangeFormatting.docx", FileFormat.Docx2019)

# Dispose resource
doc.Dispose()

Add New Elements to a Word Document in Python

In a Word document, most elements—such as text, images, lists, and charts—are fundamentally organized around the concept of a paragraph. To insert a new paragraph into a specific section, use the Section.AddParagraph() method.

After creating the new paragraph, you can add various elements to it by leveraging the methods and properties of the Paragraph object.

The steps to add new elements (text and images) to a Word document are as follows:

• Create a Document object.
• Load a Word file from the given file path.
• Get a specific section through Document.Sections[index] property.
• Add a paragraph to the section using Section.AddParagraph() method.
• Add text to the paragraph using Paragraph.AppendText() method.
• Add an image to the paragraph using Paragraph.AppendPicture() method.
• Save the updated document to a different Word file.

from spire.doc import *
from spire.doc.common import *

# Create an object of Document
doc = Document()

# Load a Word document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx")

# Get the last section
lastSection = doc.LastSection

# Add a paragraph to the section
paragraph = lastSection.AddParagraph()

# Add an image to the paragraph
picture = paragraph.AppendPicture("C:\\Users\\Administrator\\Desktop\\logo.png");

# Set text wrap style 
picture.TextWrappingStyle = TextWrappingStyle.TopAndBottom

# Add text to the paragraph
paragraph.AppendText("This text and the image above are added by Spire.Doc for Python.")

# Create a paragraph style
style = ParagraphStyle(doc)
style.Name = "FontStyle"
style.CharacterFormat.FontName = "Times New Roman"
style.CharacterFormat.FontSize = 12
doc.Styles.Add(style)

# Apply the style to the paragraph
paragraph.ApplyStyle(style.Name)

# Save the document to a different Word file
doc.SaveToFile("output/AddNewElements.docx", FileFormat.Docx2019)

# Dispose resource
doc.Dispose()

Remove Paragraphs from a Word Document in Python

To eliminate a specific paragraph from a document, simply invoke the ParagraphCollection.RemoveAt() method and supply the index of the paragraph you intend to delete.

The steps to remove paragraphs from a Word document are as follows:

• Create a Document object.
• Load a Word file from the given file path.
• Get a specific section through Document.Sections[index] property.
• Remove a specific paragraph from the section using Section.Paragraphs.RemoveAt() method.
• Save the updated document to a different Word file.
