fillpdf 0.7.1

A Library to fill and flatten pdfs

fillpdf

https://pypi.org/project/fillpdf/

Overview

This is a simple package to make filling pdfs much easier. I have delt with a lot projects that involve manipulating pdfs in python. I found no easy solution for writting, or flattening pdfs, so I decided to make a library to make this task much easier. As a young software engineer I kept this library really simple but practicle and am open to any input for the future!

This project primarily builds upon a forked version of pdfrw called pdfrw2.

• Fills pdfs
• Lists fields in pdf
• Flattens pdfs (Turns to a non-editable pdf)\
• Inserts Images and Text
• Rotate PDFs
• Place Images

Function Documentation

import fillpdf
from fillpdf import fillpdfs

get_form_fields (returns the data_dict)

get_form_fields(input_pdf_path, sort=False, page_number=None)

• input_pdf_path- path to your pdf you want to alter (including the pdf name could just leave as 'blank.pdf' if the pdf is in your current directory)
• sort- sorts the dictionary alphabetically if True, retains the normal pdf order if false
• page_number- (int) pass the page number you want the values from if you are just needing a single pages values or if you want to find which page a key belongs to

For Example:

fillpdfs.get_form_fields('blank.pdf')

print_form_fields (prints the data_dict)

print_form_fields(input_pdf_path, sort=False, page_number=None)

• input_pdf_path- path to your pdf you want to alter (including the pdf name could just leave as 'blank.pdf' if the pdf is in your current directory)
• sort (default = False) - sorts the dictionary alphabetically if True, retains the normal pdf order if false
• page_number- (int) pass the page number you want the values from if you are just needing a single pages values or if you want to find which page a key belongs to. The number passed must be within the page range.

For Example:

fillpdfs.print_form_fields('blank.pdf')

write_fillable_pdf

write_fillable_pdf(input_pdf_path, output_pdf_path, data_dict, flatten=False)

• input_pdf_path- path to your pdf you want to alter (including the pdf name could just leave as 'blank.pdf' if the pdf is in your current directory)
• output_pdf_path- path of where you want your pdf to write to (including the pdf name could just leave as 'new.pdf' to write to current directory)
• data_dict- dictionary that contains the fields to write to as your key and what to write to it as your value (get this from the get_form_fields function)
• flatten (default=False)- If True, then the fields will become uneditable when you write to the pdf.

For Example:

data_dict = {'Address 1 Text Box': '500 West Main Street',
'Driving License Check Box': 'Yes',
'Language 1 Check Box': 'Off',}

fillpdfs.write_fillable_pdf('blank.pdf', 'new.pdf', data_dict)

• For radio boxes ('Off' = not filled, 'Yes' = filled)
• For check boxes ('Off' or '' = not filled, 'Yes' = filled)
• For drop downs (Enter the name of the desired drop down option)
• For radio groups ('0' = The first option, '1' = The second option, '2' = the third option, etc.)

flatten_pdf

flatten_pdf(input_pdf_path, output_pdf_path, as_images=False)

• input_pdf_path- path to your pdf you want to alter (including the pdf name could just leave as 'blank.pdf' if the pdf is in your current directory)
• output_pdf_path- path of where you want your pdf to write to (including the pdf name could just leave as 'new.pdf' to write to current directory)
• as_images=False- Default is False meaning it will update each individual annotation and set it to False. True means it will convert to images and then reinsert into the pdf. Try this if the first is not working. (this image technique requires poppler.)

For Example:

fillpdfs.flatten_pdf('new.pdf', 'newflat.pdf')

rotate_page

rotate_page(deg, input_pdf_path, output_map_path, page_number)

• deg- float The x coordinate of the top left corner of the text.
• input_pdf_path- Path to the pdf you want the fields from.
• output_map_path- Path of the new pdf that is generated.

For Example:

fillpdfs.rotate_page(90, 'new.pdf', 'template-3.pdf', 1)

Command Line Use

A command line wrapper is available for this tool. Here are the two commands:

extractfillpdf

extractfillpdf input_pdf_path
or
extractfillpdf input_pdf_path -o output_json_path

• input_pdf_path- path to your pdf you want to alter (including the pdf name could just leave as 'blank.pdf' if the pdf is in your current directory)
• output_json_path- path of where you want your json file containing the fields and contents of the pdf to write to (If not included then the default will be the same name/path as the input_pdf_path but .json instead of .pdf)

For Example:

extractfillpdf blank.pdf
or
extractfillpdf blank.pdf -o data.json

insertfillpdf

insertfillpdf -j input_json_path -o output_pdf_path input_pdf_path

• input_pdf_path- path to your pdf you want to alter (including the pdf name could just leave as 'blank.pdf' if the pdf is in your current directory)
• input_json_path- path to the json file that you generated and modified with the extractfillpdf command.
• output_pdf_path- path of where you want your pdf to write to (including the pdf name could just leave as 'new.pdf' to write to current directory)

For Example:

insertfillpdf -j blank.json -o new.pdf blank.pdf
