Как повернуть и изменить размеры изображения в tkinter
Одна из функций кнопок должна поворачивать изображение,
а другая уменьшать/увеличивать размер изображения.
Как это реализовать в tkinter ?
main.py:
from tkinter import *
import PIL, os
from PIL import ImageTk, Image
while True:
try:
distanation = input('input pic dist>>>')
if distanation == 'break':
os.abort()
pil_image = Image.open(distanation)
except:
print('cant find')
else:
input()
break
#window options
window = Tk()
window.title('picture viewer(v0.14alpha)')
window.geometry('800x600')
window['bg'] = 'grey44'
for i in range(3):
window.columnconfigure(i, weight=1, minsize=70)
window.rowconfigure(i, weight=1, minsize=70)
#img
pil_image = pil_image.resize((700, 500), Image.ANTIALIAS)
pil_image.resize((18, 18))
image = ImageTk.PhotoImage(pil_image)
image_sprite = Label(window, image=image)
image_sprite.grid(row=1, column=1, padx=8)
label_pic_name = Label(window, text=distanation, fg='#ccc', bg='#555', font='Arial 14')
label_pic_name.grid(row=2, column=1)
#bottons_top
frame_top = Frame(window, width=100, height=100)
frame_top.grid(row=0, column=1)
btn1 = Button(frame_top, text="1111",

Я не сильно занимался оптимизацией и отладкой, но основные моменты реализации - определил.
Установите стартовое изображение
