Python PDF>JPG conversion with pdf2jpg

Question

I'm trying convert some PDFs into JPG, and using pdf2jpg to do this.

The code I run is:

inputPath = sys.argv[1].replace("\\", "/")
print(inputPath)

# Get parent folder of the file
parentFolder = "/".join(inputPath.split("/")[:-1])
print(parentFolder)

# Convert pdf to jpg in same folder
result = pdf2jpg.convert_pdf2jpg(inputPath, parentFolder, pages="1")
print(result)

When I run this, the error I get is:

NotADirectoryError: [WinError 267] The directory name is invalid: 'C:/Users/Username/Desktop\\test.pdf'

The weird thing is, when I run the same code with the last 2 lines commented out, I get:

C:/Users/Username/Desktop/test.pdf
C:/Users/Username/Desktop

It seems like the inputPath itself is being converted to forward slashes correctly, but then being reverted to backslashes when being referenced by pdf2jpg.

ETA: Switched to backslashes instead of forward slashes, and using raw literals. Code now as below:

inputPath = sys.argv[1]
inputPath_raw = r'%s'%inputPath
print(inputPath_raw)

parentFolder = chr(92).join(inputPath_raw.split(chr(92))[:-1])
print(parentFolder)

result = pdf2jpg.convert_pdf2jpg(inputPath_raw, parentFolder, pages="1")
print(result)

Then I give it the input:

convert.py "C:\Users\Username\Desktop\test.pdf"

And the error I see is:

NotADirectoryError: [WinError 267] The directory name is invalid: 'C:\\Users\\Username\\Desktop\\test.pdf'

Printing the variables still gives the correct output as the file paths, it's just this part which fails to recognise the path.

UPDATE:

The problem is that pdf2jpg is trying to create a directory, named after your pdf file in the outputpath. When converting the file test.pdf, it will (try to) create a directory named \test.pdf in the specified outputpath.

Since the source and destination directories are identical it will fail, because it's a filesystem limitation to have a file and a directory with the same name test.pdf in the same path.

Here is a test to create the output jpgs in inputpath + \pdf2jpg dir and it will work:

# -*- coding: utf-8 -*-    
import os
import sys
from pdf2jpg import pdf2jpg

source = sys.argv[1]
destination = os.path.dirname(source)+"\pdf2jpg"

try:
    os.mkdir(destination)
except FileExistsError:
    # pdf2jpg directory existing
    pass

result = pdf2jpg.convert_pdf2jpg(source, destination, pages="ALL")
