Image resizing in Tkinter, Python?

Question

Image processing

I'm creating a simple Tkinter game, I have an image, but I need the image to span 1 horizontally and 0.9 vertically without cropping the image. By any means, the image is only trimmed, not reduced. It is necessary that the size of the image is not set manually, but the exact amount is 0.9 from the screen vertically (it occupies the entire white background)

Answer 1

get canvas dimensions

cnv = tk.Cnavas(...) # создали канву
.....
w = cnv['width']
h = cnv['height']

fit the image to the canvas

from PIL import Image
......
image = Image.open(....) # представили изображение в виде объекта PIL.Image
scaled_image = image.resize((w,h), Image.ANTIALIAS) # растянули/сжали

draw an image on canvas

from PIL import ImageTk
image4canvas = ImageTk.PhotoImage(scaled_image) # представили изображение в виде объекта PIL,
# с которым умеет работать канва
cnv.create_image(0, 0, anchor=tk.NW, image=image4canvas) # нарисовали изображение на канве

Tkinter is, in fact, a terrible perversion, a kind of interface to functions for building a graphical user interface for some initially stillborn tcl / tk language. The best advice on Tkinter is universal: don't use it.
