How can I create an empty n*m PNG file in Python?

Question

I would like to combine 4 PNG images to one PNG file. I know who to combine them with Image.paste method, but I couldn't create an save output file! Actually, I want to have a n*m empty PNG file, and use to combine my images. I need to specify the file size, if not I couldn't use paste method.

Answer 1

from PIL import Image image = Image.new('RGB', (n, m)) 

Answer 2

You can use the method PIL.Image.new() to create the image. But the default color is in black. To make a totally white-background empty image, you can initialize it with the code:

from PIL import Image img = Image.new("RGB", (800, 1280), (255, 255, 255)) img.save("image.png", "PNG") 

It creates an image with the size 800x1280 with white background.
