I don't know how to combine multiple pngs into one tiff.

import glob
from PIL import Image

Wildcards in the dir=r "img/*.png" #png file
save_path="hoge.tif"# output file path

stack = [ Image.open(p) for ping glob.glob(dir) ]

stack[0].save(save_path, compression="tiff_deflate", save_all=True, append_images=stack[1:])
