根据python中的显性colors，将图像的colors个数限制为指定个数

Question

I want to process images in a way to limit the number of colors to a predetermined and specific number

I tried using this method

from PIL import image

image= Image.open("input.png")
result = image.convert('P', palette=Image.ADAPTIVE, colors=2)
result.save("saved.png")

for some reason it used to work but now doesn't work i'm pretty sure i didn't change anything

is there a fix or another method? thanks

FIXED: the problem is the color mode to be able to use this function you need first to convert the color mode of the image to RGB like this:

image = image.convert('RGB')
