Add an Image Stamp to PDF Documents in Python
Spire.PDF for Python offers the PdfRubberStampAnnotation class to represent a rubber stamp in a PDF document. In order to create the appearance of a rubber stamp, the PdfTemplate class is used. The PdfTemplate is a piece of canvas on which you can draw whatever information you want, such as text, images, date, and time.
Image stamps can include logos, signatures, watermarks, or any other custom graphics that you want to overlay onto your PDFs. The main steps to add an image stamp to PDF using Spire.PDF for Python are as follows.
- Create a PdfDocument object.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Load an image that you want to stamp on PDF using PdfImage.FromFile() method.
- Create a PdfTemplate object with the dimensions of the image.
- Draw the image on the template using PdfTemplate.Graphics.DrawImage() method.
- Create a PdfRubberStampAnnotation object, and set the template as its appearance.
- Add the stamp to a specific PDF page using PdfPageBase.AnnotationsWidget.Add() method.
- Save the document to a different file using PdfDocument.SaveToFile() method.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pdf")
# Get a specific page
page = doc.Pages.get_Item(2)
# Load an image file
image = PdfImage.FromFile("C:\\Users\\Administrator\\Desktop\\secret.png")
# Get the width and height of the image
width = (float)(image.Width)
height = (float)(image.Height)
# Create a PdfTemplate object based on the size of the image
template = PdfTemplate(width, height, True)
# Draw image on the template
template.Graphics.DrawImage(image, 0.0, 0.0, width, height)
# Create a rubber stamp annotation, specifying its location and position
rect = RectangleF((float) (page.ActualSize.Width - width - 50), (float) (page.ActualSize.Height - height - 40), width, height)
stamp = PdfRubberStampAnnotation(rect)
# Create a PdfAppearance object
pdfAppearance = PdfAppearance(stamp)
# Set the template as the normal state of the appearance
pdfAppearance.Normal = template
# Apply the appearance to the stamp
stamp.Appearance = pdfAppearance
# Add the stamp annotation to PDF
page.AnnotationsWidget.Add(stamp)
# Save the file
doc.SaveToFile("output/ImageStamp.pdf")
doc.Close()
Add a Dynamic Stamp to PDF in Python
Unlike static stamps, dynamic stamps can contain variable information such as the date, time, or user input. The following are the steps to create a dynamic stamp in PDF using Spire.PDF for Python.

font1 = PdfTrueTypeFont("Elephant", 16.0, 0, True)
font2 = PdfTrueTypeFont("Times New Roman", 10.0, 0, True)
# Create a solid brush and a gradient brush
solidBrush = PdfSolidBrush(PdfRGBColor(Color.get_Blue()))
rectangle1 = RectangleF(PointF(0.0, 0.0), template.Size)
linearGradientBrush = PdfLinearGradientBrush(rectangle1, PdfRGBColor(Color.get_White()), PdfRGBColor(Color.get_LightBlue()), PdfLinearGradientMode.Horizontal)
# Create a pen
pen = PdfPen(solidBrush)
# Create a rounded rectangle path
CornerRadius = 10.0
path = PdfPath()
path.AddArc(template.GetBounds().X, template.GetBounds().Y, CornerRadius, CornerRadius, 180.0, 90.0)

path.AddArc(template.GetBounds().X, template.GetBounds().Y + template.Height - CornerRadius, CornerRadius, CornerRadius, 90.0, 90.0)
path.AddLine(template.GetBounds().X, template.GetBounds().Y + template.Height - CornerRadius, template.GetBounds().X, template.GetBounds().Y + CornerRadius / 2)
# Draw path on the template
template.Graphics.DrawPath(pen, path)
template.Graphics.DrawPath(linearGradientBrush, path)
# Draw text on the template
string1 = "APPROVED\n"
string2 = "By Marketing Manager at " + DateTime.get_Now().ToString("HH:mm, MMM dd, yyyy")
template.Graphics.DrawString(string1, font1, solidBrush, PointF(5.0, 5.0))
template.Graphics.DrawString(string2, font2, solidBrush, PointF(2.0, 28.0))
# Create a rubber stamp, specifying its size and location

Create a Numbered List in Word in Python
Spire.Doc for Python provides the ListStyle class, which enables you to establish either a numbered list style or a bulleted style. Subsequently, you can utilize the Paragraph.ListFormat.ApplyStyle() method to apply the defined list style to a paragraph. The steps to create a numbered list are as follows.
- Create a Document object.
- Add a section using Document.AddSection() method.

Create a Multi-Level Numbered List in Word in Python
A multi-level list consists of at least two different levels. A certain level of a nested list can be accessed by the ListStyle.Levels[index] property, through which you can set the numbering type and prefix. The following are the steps to create a multi-level numbered list in Word.
- Create a Document object.
- Add a section using Document.AddSection() method.
- Create an instance of ListStyle class, specifying the list type to Numbered.

- Add the list style to the document using Document.ListStyles.Add() method.
- Add several paragraphs to the document using Section.AddParagraph() method.
- Apply the list style to a specific paragraph using Paragraph.ListFormat.ApplyStyle() method.
- Specify the list level through Paragraph.ListFormat.ListLevelNumber property.
- Save the document to a Word file using Document.SaveToFile() method.
- Python

listStyle = doc.Styles.Add(ListType.Numbered,"levelstyle")
Levels = listStyle.ListRef.Levels
Levels[0].PatternType = ListPatternType.Arabic
Levels[0].TextPosition = 20.0
Levels[1].NumberPrefix = "%1."
Levels[1].PatternType = ListPatternType.Arabic
Levels[2].NumberPrefix = "%1.%2."
Levels[2].PatternType = ListPatternType.Arabic
# Add a paragraph
paragraph = section.AddParagraph()
paragraph.AppendText("Here's a Multi-Level Numbered List:")

# Add a paragraph and apply the numbered list style to it
paragraph = section.AddParagraph()
paragraph.AppendText("The first item")
paragraph.ListFormat.ApplyStyle("levelstyle")
paragraph.ListFormat.ListLevelNumber = 0
# Add another five paragraphs and apply the numbered list stype to them
paragraph = section.AddParagraph()
paragraph.AppendText("The second item")
paragraph.ListFormat.ApplyStyle("levelstyle")
paragraph.ListFormat.ListLevelNumber = 0
paragraph = section.AddParagraph()
paragraph.AppendText("The first sub-item")
