Draw lines using PyPDF

Question

I am currently merging two pages into a single page in PyPDF3 but I need to draw a line in the middle of the two pages. Is this possible? Below is the sample code for reference. Thanks in advance!

from PyPDF3 import PdfFileWriter, PdfFileReader
from PyPDF3.pdf import PageObject

pdf_file = "Plan.pdf"

inputPDF = PdfFileReader(open(pdf_file, "rb"), strict=False)
outputPDF = PdfFileWriter()

for x in range(0, inputPDF.numPages, 2):
    page1 = inputPDF.getPage(x).rotateClockwise(90)
    page2 = inputPDF.getPage(x + 1).rotateClockwise(90)
    
    total_width = max([page1.mediaBox.upperRight[0],page2.mediaBox.upperRight[0]])
    total_height = page1.mediaBox.upperRight[1] + page2.mediaBox.upperRight[1]
    
    new_page = PageObject.createBlankPage(None, total_width, total_height)
    
    new_page.mergeTranslatedPage(page1, 0, page1.mediaBox.upperRight[1])
    new_page.mergeTranslatedPage(page2, 0, 0)    
    
    outputPDF.addPage(new_page.rotateCounterClockwise(90))
    
outputFile = "Merged_Plan.pdf"
outputPDF.write(open(outputFile, "wb"))

You can use the Line annotation: https://pypdf.readthedocs.io/en/latest/user/adding-pdf-annotations.html#line

It was recently added to pypdf. You might need to update your installed version.

I recommend to switch away from PyPDF2 / PyPDF3 / PyPDF4 towards pypdf.
