Replace Image with New Image in Word in Python

Spire.Doc for Python supports not only inserting images in Word, but also replacing existing images. The following are the detailed steps to get a specific image in Word and then replace it with a new image.

• Create a Document object.
• Load a Word document using Document.LoadFromFile() method.
• Create a list to store the images.
• Iterate through all sections in the document.
• Iterate through all paragraphs in each section.
• Iterate through all child objects in each paragraph.
• Find the images and add them to the list.
• Get a specific image from the list and replace it with another image using DocPicture.LoadImage() method.
• Save the result document using Document.SaveToFile() method.

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

# Create a Document object
doc = Document()

# Load a Word document
doc.LoadFromFile("Data.docx")

# Create a list to store the images
pictures = []

# Iterate through all sections in the document
for i in range(doc.Sections.Count):
    sec = doc.Sections.get_Item(i)

    # Iterate through all paragraphs in each section
    for j in range(sec.Paragraphs.Count):
        para = sec.Paragraphs.get_Item(j)

        # Iterate through all child objects in each paragraph
        for k in range(para.ChildObjects.Count):
            docObj = para.ChildObjects.get_Item(k)

            # Find the images and add them to the list
            if docObj.DocumentObjectType == DocumentObjectType.Picture:
                pictures.append(docObj)

# Replace the first picture in the list with a new image
picture = pictures[0] if isinstance(pictures[0], DocPicture) else None
picture.LoadImage("data.jpg")

# Save the result document
doc.SaveToFile("ReplaceImage.docx", FileFormat.Docx)
doc.Close()

Replace Image with Text in Word in Python

Spire.Doc for Python doesn't provide a direct method to replace image with text, but you can achieve this task by inserting text at the image location and then removing the image from the document.

The following are the steps to replace all images in a Word document with text:

• Create a Document object.
• Load a Word document using Document.LoadFromFile() method.
• Iterate through all sections in the document.
• Iterate through all paragraphs in each section.
• Create a list to store the images.
• Iterate through all child objects in each paragraph.
• Find the images and add them to the list.
• Iterate through the images in the list.
• Get the index of the image in the paragraph using Paragraph.ChildObjects.Indexof() method.
• Initialize an instance of TextRange class and set text for the text range through TextRange.Text property.
• Insert the text range at the image location using Paragraph.ChildObjects.Insert() method.
• Remove the image from the paragraph using Paragraph.ChildObjects.Remove() method.
• Save the result document using Document.SaveToFile() method.

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

# Create a Document object
doc = Document()

# Load a Word document
doc.LoadFromFile("Data.docx")

j = 1
# Iterate through all sections in the document
for k in range(doc.Sections.Count):
    sec = doc.Sections.get_Item(k)

    # Iterate through all sections in the document
    for m in range(sec.Paragraphs.Count):
        para = sec.Paragraphs.get_Item(m)

        # Create a list to store the images
        pictures = []

        # Find the images and add them to the list
        for x in range(para.ChildObjects.Count):
            docObj = para.ChildObjects.get_Item(x)
            if docObj.DocumentObjectType == DocumentObjectType.Picture:
                pictures.append(docObj)

        # Iterate through all images in the list and replace them with text "Here is image {image index}"
        for pic in pictures:
            index = para.ChildObjects.IndexOf(pic)
            textRange = TextRange(doc)
            textRange.Text = "Here is image {0}".format(j)
            para.ChildObjects.Insert(index, textRange)
            para.ChildObjects.Remove(pic)
            j += 1

# Save the result document
doc.SaveToFile("ReplaceWithText.docx", FileFormat.Docx)
doc.Close()

When working with Word documents, sometimes you may need to adjust the content or layout of the document by deleting certain paragraphs. For example, when you have copied a very long paragraph from the Internet, you can delete redundant paragraphs as needed and keep only the useful ones. Or you can create a new document by deleting irrelevant paragraphs in an existing document. In this case, performing this process programmatically is a better option than tedious manual deletion, which can help you batch process a large number of documents in a short period of time. In this article, we will show you how to remove a specific paragraph or all paragraphs from Word documents in python using Spire.Doc for Python.

Delete a Specific Paragraph from Word Documents

With Spire.Doc for Python library, you are allowed to remove specific paragraphs from Word documents. You just need to get the desired section, and then call the Section.Paragraphs.RemoveAt() method to remove the paragraphs you want. The detailed steps are as follows.

• Create an object of Document class.
• Load a Word document from disk using Document.LoadFromFile() method.
• Get the first section of this file using Document.Sections[] property.
• Remove the first paragraph from this section using Section.Paragraphs.RemoveAt() method.
• Save the result file using Document.SaveToFile() method.

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

inputFile = "C:/Users/Administrator/Desktop/Sample.docx"
outputFile = "C:/Users/Administrator/Desktop/RemoveParagraphs.docx"
    
#Create an object of Document class
document = Document()

#Load a sample file from disk
document.LoadFromFile(inputFile)

#Get the first section of this file
section=document.Sections[0]

#Remove the first paragraph from this section
section.Paragraphs.RemoveAt(0)

#Save the result file
document.SaveToFile(outputFile, FileFormat.Docx2013)
document.Close()

Delete All Paragraphs from Word Documents

In addition, if you want to clear all paragraphs of the Word document at once, please loop through all sections first and call the Section.Paragraphs.Clear() method to do that. The detailed steps are as follows.

• Create an object of Document class.
• Load a Word document from disk using Document.LoadFromFile() method.
• Loop through all sections first and remove all paragraphs in each section by using Section.Paragraphs.Clear() method.
• Save the result file using Document.SaveToFile() method.

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

inputFile = "C:/Users/Administrator/Desktop/Sample.docx"
outputFile = "C:/Users/Administrator/Desktop/RemoveAllParagraphs.docx"
    
#Create an object of Document class
document = Document()

#Load a sample file from disk
document.LoadFromFile(inputFile)

#Remove paragraphs from the body of every section in the document
for i in range(document.Sections.Count):
    section = document.Sections.get_Item(i)
    section.Paragraphs.Clear()

#Save the result file
document.SaveToFile(outputFile, FileFormat.Docx2013)
document.Close()
