• Add a textbox to the worksheet at the specified location using Worksheet.TextBoxes.AddTextBox() method.
• Set text of the textbox through TextBox.Text property.
• Set formatting of the text through other properties under the TextBox object.
• Save the workbook to an Excel file using Workbook.SaveToFile() method.

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()

# Get the first worksheet
sheet = workbook.Worksheets[0]

# Add a textbox to the worksheet, specifying location and size
textBox = sheet.TextBoxes.AddTextBox(5, 3, 120, 300)

# Set fill color of the textbox
textBox.Fill.FillType = ShapeFillType.SolidColor
textBox.Fill.ForeKnownColor = ExcelColors.Gray25Percent

# Add text to the textbox and set the text alignment
textBox.Text = "This is a textbox in Excel."
textBox.HAlignment = CommentHAlignType.Center
textBox.VAlignment = CommentVAlignType.Center

# Set font for the text
font = workbook.CreateFont()
font.FontName = "Times New Roman"
font.Size = 18
font.IsBold = True
font.Color = Color.get_Blue()
richText = textBox.RichText
rt = RichText(richText)
rt.SetFont(0, len(textBox.Text) - 1, font)

# Save the workbook to an Excel file
workbook.SaveToFile('output/InsertTextbox.xlsx', ExcelVersion.Version2016)
workbook.Dispose()

Update a Textbox in Excel in Python

A certain textbox can be accessed through Worksheet.TextBoxes[index] property and the text inside the box can be obtained or modified through TextBox.Text property. The following are the steps to update a textbox using Spire.XLS for Python.

• Load an Excel file using Workbook.LoadFromFile() method.
• Get a specific worksheet through Workbook.Worksheets[index] property.
• Add a textbox to the worksheet at the specified location using Worksheet.TextBoxes.AddTextBox() method.
• Reset text of the textbox through TextBox.Text property.
• Save the workbook to a different Excel file using Workbook.SaveToFile() method.

from spire.xls import *
from spire.common import *

# Create a Workbook object
workbook = Workbook()

# Load an Excel file
workbook.LoadFromFile('C:\\Users\\Administrator\\Desktop\\Textbox.xlsx')

# Get the first worksheet
sheet = workbook.Worksheets[0]

# Get the first textbox
tb = sheet.TextBoxes[0]

# Change the text of textbox
tb.Text = "The text in this textbox was changed."

# Save the workbook to a different Excel file
workbook.SaveToFile('output/UpdateTextbox.xlsx', ExcelVersion.Version2016)
workbook.Dispose()

Extracting images from a PowerPoint presentation is necessary when you need to reuse them elsewhere. By doing so, you gain the flexibility to use these images outside the confines of the original presentation, thus maximizing their value in different projects. This article will demonstrate how to extract images from a PowerPoint document in Python using Spire.Presentation for Python.

• Extract Images from a Presentation Slide

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

Extract Images from a PowerPoint Document in Python

To extract images from an entire PowerPoint presentation, you need to use the Presentation.Images property to get the collection of all the images in the presentation, then iterate through the elements in the collection and call IImageData.Image.Save() method to save each element to an image file. The following are the detailed steps:

• Create a Presentation instance.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get the collection of all the images in the document using Presentation.Images property.
• Iterate through the elements in the collection, and save each element as an image file using the IImageData.Image.Save() method.

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

# Create a Presentation instance
ppt = Presentation()

# Load a PowerPoint document
ppt.LoadFromFile("sample.pptx")

# Iterate through all images in the document
for i, image in enumerate(ppt.Images):

    # Extract the images
    ImageName = "ExtractImage/Images_"+str(i)+".png"
    image.Image.Save(ImageName)

ppt.Dispose()

Extract Images from a Presentation Slide in Python

To extract images from a specific slide, you need to iterate through all shapes on the slide and find the shapes that are of SlidePicture or PictureShape type, then use the SlidePicture.PictureFill.Picture.EmbedImage.Image.Save() or PictureShape.EmbedImage.Image.Save() method to save the images to image files. The following are the detailed steps:

• Create a Presentation instance.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Get a specified slide using Presentation.Slides[int] property.
• Iterate through all shapes on the slide.
• Determine whether the shapes are of SlidePicture or PictureShape type. If so, save the images to image files using SlidePicture.PictureFill.Picture.EmbedImage.Image.Save() or PictureShape.EmbedImage.Image.Save() method.

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

# Create a Presentation instance
ppt = Presentation()

# Load a PowerPoint document
ppt.LoadFromFile("sample.pptx")

# Get a specified slide
slide = ppt.Slides[2];

i = 0
#Traverse all shapes in the slide
for s in slide.Shapes:

    # Determine if the shape is of SlidePicture type
    if isinstance(s, SlidePicture):

        # If yes, then extract the image
        ps = s if isinstance(s, SlidePicture) else None
        ps.PictureFill.Picture.EmbedImage.Image.Save("Output/SlidePic_"+str(i)+".png")
        i += 1

    # Determine if the shape is of PictureShape type
    if isinstance(s, PictureShape):

        # If yes, then extract the image
        ps = s if isinstance(s, PictureShape) else None
        ps.EmbedImage.Image.Save("Output/SlidePic_"+str(i)+".png")
        i += 1

ppt.Dispose()
