How to merge a transparent png image with another image using PIL
image, image-processing, python, python-imaging-library
Solution
from PIL import Image
background = Image.open("test1.png")
foreground = Image.open("test2.png")
background.paste(foreground, (0, 0), foreground)
background.show()
First parameter to `.paste()` is the image to paste. Second are coordinates, and the secret sauce is the third parameter. It indicates a mask that will be used to paste the image. If you pass a image with transparency, then the alpha channel is used as mask.
Check the docs.
Problem
I have a transparent png image `foo.png` and I've opened another image with: ``` im = Image.open("foo2.png") ``` Now what I need is to merge `foo.png` with `foo2.png`. (`foo.png` contains some text and I want to print that text on `foo2.png`)
