Images To PDF

from ironpdf import *

# One or more images as a list. This example selects all JPEG images in a specific 'assets' folder.
image_files = [os.path.join("assets", f) for f in os.listdir("assets") if f.lower().endswith(('.jpg', '.jpeg'))]

directory_list = List[str]()
for i in range(len(image_files)):
    directory_list.Add(image_files[i])

# Converts the images to a PDF and save it.
ImageToPdfConverter.ImageToPdf(directory_list).SaveAs("composite.pdf")

# Also see PdfDocument.RasterizeToImageFiles() method to flatten a PDF to images or thumbnails

Images To PDF

The ImageToPdfConverter class creates PDF documents from images.

Call the ImageToPdfConverter.ImageToPdf function using a valid file path to an image to produce a new PDF document from that image.

Calling ImageToPdfConverter.ImageToPdf using a list of image paths will produce a single PDF document containing each image on separate pages.

PYTHON

Import necessary modules: FPDF for creating PDF files, Image from PIL for processing images, and os for file operations.
The method image_to_pdf takes one or multiple image paths and converts them into a PDF file, saving it at the specified output path.
Images are converted to RGB to ensure compatibility.
Temporary files are used to maintain the consistency of image formats.
The method handles single image paths and lists of image paths seamlessly.
