How to crop from one image and paste into another with PIL?
With PIL, I am trying to copy a rectangle out of an image, and paste it into another. This is my code:
import Image
ii = Image.open("ramza.png")
box = (70, 70, 30, 30)
region = ii.crop(box)
io = Image.open("template.png")
io.paste(region, box)
io.save("output.png")
And I am getting this error:
ValueError: images do not match
Do any of you know a fix to this?
Answer
A PIL crop box is defined as a 4-tuple of pixel coordinates: (left, upper, right, lower).
To fix your code to get a 30x30 crop:
box = (70, 70, 100, 100)
Broken down into components:
x, y, w, h = (70, 70, 30, 30)
box = (x, y, x + w, y + h)
