Restrict Editing of Entire Word Documents with Passwords

There are four types or editing restrictions in Word documents: No changes (Read only), Tracked changes, Comments, and Filling in forms. Spire.Doc for Python provides the Document.Protect() method set editing restrictions and ProtectionType Enum to represent the restriction types.

Here is a list of the ProtectionType Enum and the corresponding editing restrictions:

The steps for setting editing restrictions with a password on Word documents are as follows:

• Create an object of Document class.
• Load a Word document using Document.LoadFromFile() method.
• Set specified editing restrictions on the document using Document.Protect(type:ProtectionType, password:str) method.
• Save the document using Document.SaveToFile() method.

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

# Create an object of Document class
doc = Document()

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

# Set the editing restriction type to No changes (Read only)
doc.Protect(ProtectionType.AllowOnlyReading, "password")

# Set the editing restriction type to Tracked changes
# doc.Protect(ProtectionType.AllowOnlyRevisions, "password")

# Set the editing restriction type to Comments
# doc.Protect(ProtectionType.AllowOnlyComments, "password")

# Set the editing restriction type to Filling in forms
# doc.Protect(ProtectionType.AllowOnlyFormFields, "password")

# Save the document
doc.SaveToFile("output/EditingRestrictions.docx")
doc.Close()

Set Exceptions to Word Document Editing Restrictions

Users can add exceptions (unrestricted areas) when setting editing restrictions on Word documents by inserting permission starting and ending tags. The details steps are as follows:

• Create an object of Document class.
• Load a Word document using Document.LoadFromFile() method.
• Get the first section using Document.Sections.get_Item() method.
• Create an object of PermissionStart class and an object of PermissionEnd class.
• Insert the permission start tag and the end tag to the document using Paragraph.ChildObjects.Insert() method and Paragraph.ChildObjects.Add() method.
• Set the editing restriction using Document.Protect() method.
• Save the document using Document.SaveToFile() method.

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

# Create an object of Document class
doc = Document()

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

# Get the first section
section = doc.Sections.get_Item(0)

# Create a permission start tag and an end tag
start = PermissionStart(doc, "exception1")
end = PermissionEnd(doc, "exception1")

# Insert the permission start tag and the end tag to the first section
paragraph = section.Paragraphs.get_Item(1)
paragraph.ChildObjects.Insert(0,start)
paragraph.ChildObjects.Add(end)

# Set the editing restriction
doc.Protect(ProtectionType.AllowOnlyReading, "password")

# Save the document
doc.SaveToFile("output/RestrictionException.docx")
doc.Close()

Remove Editing Restrictions from Word Documents

To remove the editing restrictions of a document, simply set the editing restriction type to no restriction using the Document.Protect() method. The detailed steps are as follows:

• Create an object of Document class.
• Load a Word document using Document.LoadFromFile() method.
• Remove the restriction by setting the restriction type to None using Document.Protect() method.
• Save the document using Document.SaveToFile() method.

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

# Create an object of Document class
doc = Document()

# Load a Word document
doc.LoadFromFile("output/EditingRestrictions.docx")

# Remove the editing restriction by set the restriction type to None
doc.Protect(ProtectionType.NoProtection)

# Save the document
doc.SaveToFile("output/RemoveEditingRestriction.docx")
doc.Close()

# Get the folder where the images are stored
path = 'C:/Users/Administrator/Desktop/Images/'
files = os.listdir(path)

# Iterate through the files in the folder
for root, dirs, files in os.walk(path):
    for file in files:

        # Load a particular image 
        image = PdfImage.FromFile(os.path.join(root, file))  #FromFile(os.path.join(root, file))
    
        # Get the image width and height
        width = image.PhysicalDimension.Width
        height = image.PhysicalDimension.Height

        # Add a page that has the same size as the image
        page = doc.Pages.Add(SizeF(width, height))

        # Draw image at (0, 0) of the page
        page.Canvas.DrawImage(image, 0.0, 0.0, width, height)
      
# Save to file
doc.SaveToFile('output/ConvertImagesToPdf.pdf')
doc.Dispose();
