A PDF portfolio is a collection of files assembled into a single PDF document. It serves as a comprehensive and interactive showcase of various types of content, such as documents, images, presentations, videos, and more. Unlike a traditional PDF document, a PDF portfolio allows you to present multiple files in a cohesive and organized manner, providing a seamless browsing experience for the viewer. In this article, we will demonstrate how to create a PDF portfolio and how to identify if a PDF is a portfolio in Python using Spire.PDF for Python.

Create a PDF Portfolio with Python

Spire.PDF for Python allows you to generate a PDF portfolio by adding files to a PDF using the PdfDocument.Collection.AddFile() method. Furthermore, you can organize the files within the PDF portfolio by adding folders using the PdfDocument.Collection.Folders.CreateSubfolder() method. The detailed steps are as follows.

• Specify the output file path and the folders where the files to be included in the PDF portfolio are located.
• Create a PdfDocument object.
• Iterate through the files in the first folder and add them to the PDF portfolio using the PdfDocument.Collection.AddFile() method.
• Iterate through the files in the second folder. For each file, create a separate folder within the PDF portfolio using the PdfDocument.Collection.Folders.CreateSubfolder() method, and then add the file to the corresponding folder using the PdfFolder.AddFile() method.
• Save the resulting PDF portfolio using the PdfDocument.SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *
import glob

# Specify the folders where the files to be included in the PDF portfolio are located
input_folder1 = "Folder1/*"
input_folder2 = "Folder2/*"
# Specify the output file path
output_file = "CreatePDFPortfolio.pdf"

# Create a PdfDocument object
doc = PdfDocument()

# Get the list of file paths in the first folder
files1 = glob.glob(input_folder1)
# Loop through the files in the list
for i, file in enumerate(files1):
    # Add each file to the PDF portfolio
    doc.Collection.AddFile(file)

# Get the list of file paths in the second folder
files2 = glob.glob(input_folder2)
# Loop through the files in the list
for j, file in enumerate(files2):
    # Create a separate folder for each file
    folder = doc.Collection.Folders.CreateSubfolder(f"SubFolder{j + 1}")
    # Add the file to the folder
    folder.AddFile(file)

# Save the resulting PDF portfolio to the specified file path
doc.SaveToFile(output_file)

# Close the PdfDocument object
doc.Close()

Identify if a PDF is a Portfolio with Python

You can use the PdfDocument.IsPortfolio property to easily identify whether a PDF document is a portfolio or not. The detailed steps are as follows.

• Specify the input and output file paths.
• Create a PdfDocument object.
• Load a PDF document using the PdfDocument.LoadFromFile() method.
• Identify whether the document is a portfolio or not using the PdfDocument.IsPortfolio property.
• Save the result to a text file.

from spire.pdf.common import *
from spire.pdf import *

# Specify the input and output file paths
input_file = "CreatePDFPortfolio.pdf"
output_file = "IsPDFPortfolio.txt"

# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile(input_file)

# Identify whether the document is a portfolio or not
if doc.IsPortfolio:
    st = "The document is a portfolio"
else:
    st = "The document is not a portfolio"

# Save the result to a text file
with open(output_file, "w") as text_file:
    text_file.write(st)

# Close the PdfDocument object
doc.Close()

    # Specify watermark text
    watermarkText = "DO NOT COPY"

    # Get text size
    fontSize = font.MeasureString(watermarkText)

    # Get page count
    pageCount = doc.Pages.Count

    # Loop through the pages
    for i in range(0, pageCount):

        # Get a specific page
        page = doc.Pages[i]

        # Create canvas for layer
        canvas = layer.CreateGraphics(page.Canvas)

        # Draw sting on the graphics
        canvas.DrawString(watermarkText, font, PdfBrushes.get_Gray(), (canvas.Size.Width - fontSize.Width)/2, (canvas.Size.Height - fontSize.Height)/2 )

# Create a PdfDocument instance
doc = PdfDocument()

# Load a PDF file
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pdf")
