Python pdf library installation, script

[[Ra...]]

Hi,

I need help installing a Python library "pypdf" to combine pdf from different reports. Ultimately I want to make a script that combines pdf files from several reports into one file and save it under a different name, Each pdf file or page is always to be added to the end of the file ready to be save as. I work on GOM Scanbox 6, Atos 2020 nad 20222. Sample script in attachment  - pdf.txt

pdf.txt

You already provided a mostly working solution.
 

In ZEISS INSPECT 2025, you install Python packages with the App Editor as follows:

ZEISS INSPECT 2025 provides the `choose_file()` command (see Selecting a file or folder), which can be configured interactively to request an existing folder, an existing file or a new file as in the following script:

import gom

import os
from PyPDF2 import PdfMerger

def merge_pdfs_with_last_file(input_folder, last_file, output_file):
	# Creating a PdfMerger object
	merger = PdfMerger()

	# Retrieving all PDF files in the folder
	pdf_files = [file for file in os.listdir(input_folder) if file.endswith('.pdf')]

	# Sorting files alphabetically (optional)
	pdf_files.sort()

	# Adding PDF files to the PdfMerger object
	for pdf in pdf_files:
		pdf_path = os.path.join(input_folder, pdf)
		if os.path.abspath(pdf_path) != os.path.abspath(last_file):  # Skipping the file specified to be at the end
			merger.append(pdf_path)

	# Adding the file that should be at the end
	merger.append(last_file)

	# Saving the merged PDF file
	merger.write(output_file)
	merger.close()

	print(f"Merged PDF files and saved as '{output_file}'")


if __name__ == "__main__":
	# Location of the folder with PDF files
	input_folder=gom.script.sys.choose_file (selection_type='select directory')

	# Path to the file that should be added at the end
	last_file=gom.script.sys.choose_file (
		file_types=[['*.pdf', 'PDF files'], ['*.*', 'All files']], 
		file_types_default='*.pdf', 
		folder='', 
		file='', 
		selection_type='load file')

	# Location of the output file
	output_file=gom.script.sys.choose_file (
		file_types=[], 
		file_types_default='', 
		folder='', 
		file='', 
		selection_type='new file')

	merge_pdfs_with_last_file(input_folder, last_file, output_file)

As an alternative, you create a user-defined dialog with File Widgets, which also works in older versions of ZEISS INSPECT.

Best regards,

Matthias

BTW: You can also use pypdf (which is newer than PyPDF2) with minimal modifications:

[...]
from pypdf import PdfWriter

def merge_pdfs_with_last_file(input_folder, last_file, output_file):
	# Creating a PdfWriter (formerly PdfMerger) object
	merger = PdfWriter()
    [...]

Thanks for your help and information. I downloaded the pypdf package, during installation I don't want to overwite data the current py files, because the installed ones are used in other processes. I would like to be sure that my pypdf package will not affect the work of Atos and the scanning robot, so the installation must be on the user folder - "test pypdf". This is the first time I install the py package on Atos Scanbox.
