将 JPG 转换为 PNG

Question

I have used the below code to

convert JPG into PNG file:

But when i am running this code from the command line terminal using: python a.py "C:\\Users\\nishant.gupta2\\PycharmProjects\\jpgtopngconverter\\photo" new

The system is giving me the error:

 PermissionError: [Errno 13] Permission denied: 'C:\\Users\\nishant.gupta2\\PycharmProjects\\jpgtopngconverter\\photo'

My code is below:

import sys
import os
from PIL import Image

image_folder=sys.argv[1]

output_folder=sys.argv[2]

if not os.path.exists(output_folder):
    os.mkdir(output_folder)


for items in os.listdir(image_folder):

    im= Image.open(f'{image_folder}')
    im.save(f'{output_folder}.png','png')

Answer 1

It looks like this has to do with file permissions rather than your code. Your code is running under a separate user than the image folder you are specifying, depending on admin status you may get permission issues.

Answer 2

You are trying to open a folder here :

im= Image.open(f'{image_folder}')

rather then image. You should specify the path of image.
