Below is my code, Please help me on this

import chardet

import PyPDF2

import re

from PyPDF2 import PdfFileWriter, PdfFileReader
from PyPDF2.generic import TextStringObject, BooleanObject, NameObject, DictionaryObject, ArrayObject,PdfObject

def add_checkbox_to_page(page, x, y, width, height):
checkbox = {
"/Type": "/Annot",
"/Subtype": "/Widget",
"/FT": "/Btn",
"/T": TextStringObject("Checkbox"),
"/Rect": [x, y, x + width, y + height],
"/V": TextStringObject("Yes"),
"/AP": DictionaryObject(
{
"/N": DictionaryObject({NameObject("/Off"): TextStringObject("[]"), NameObject("/Yes"): TextStringObject("[/On]")}),
"/D": DictionaryObject({NameObject("/Off"): TextStringObject("0 0 R"), NameObject("/Yes"): TextStringObject("1 0 R")}),
}
),
"/AS": NameObject("/Yes"),
"/H": TextStringObject("N"),
}
#page[NameObject("/Annots")].append(DictionaryObject(checkbox))
page[NameObject("/Annots")] = ArrayObject([DictionaryObject(checkbox)])

def add_checkboxes_to_pdf(input_pdf, output_pdf):
pdf_reader = PdfFileReader(input_pdf)
pdf_writer = PdfFileWriter()

for page_number in range(len(pdf_reader.pages)):
    page = pdf_reader.pages[page_number]
    add_checkbox_to_page(page, x=100, y=600, width=20, height=20)  # Adjust the coordinates as needed for checkbox position
    pdf_writer.addPage(page)

with open(output_pdf, "wb") as output_file:
    pdf_writer.write(output_file)

# pdf_output_file = open("D:\\Pawan\\temp\\25\\check\\AJC26740OUT.pdf", 'wb')
# pdf_writer.write(pdf_output_file)

Call the function to add checkboxes to the PDF

add_checkboxes_to_pdf("D:\Pawan\temp\25\check\test.pdf", "D:\Pawan\temp\25\check\AJC26740_OUT.pdf")
