Why does Tkinter Canvas widget show images at a wrong scale?

I'm trying to open image files and display them in python 3.8 using Tkinter and Pillow, but something is scaling the images wrong on my screen.
import tkinter as tk
from PIL import Image, ImageTk
class ViewingWindow(tk.Frame):
def __init__(self, parent):
tk.Frame.__init__(self, parent)
self.image = None
self.canvas = tk.Canvas(self, width=500, height=500)
self.canvas.pack()
def setImage(self, img):
self.image = img
print(img.width())
print(img.height())
print(self.canvas["width"])
print(self.canvas["height"])
self.canvas.create_image(0, 0, anchor=tk.NW, image=img)
window = tk.Tk()
canvas = ViewingWindow(window)
canvas.pack()
img = Image.open("500x500.jpg")
img = ImageTk.PhotoImage(img)
canvas.setImage(img)
window.mainloop()
This is the result, shown for reference is Windows image viewer at "show actual size", and Gimp at scaling=100%:
The 4 print statements all show "500", every part of the system seems to agree that the image is shown at 500x500, except the actual pixels on the screen. For whatever reason it's scaled to something close to 750x750, what in the world is scaling my image? This is consistent for all images I've tried to open in Tkinter, and regardless on window size and widget sizes.
Tested on Windows 10 with screen resolution 1920x1080.

it's scaled to something close to 750x750
750/500 = 150%.It seems that your system zoom ratio is 150%.
To show the right image size.Just like furas said,you need to use DPI awareness.Read the problem in MSDN official doc
About DPI awareness.
To solve the problem,you can set the DPI awareness in your code.(Or you can change the zoom ratio to 100%)
In my PC,the are not the same size without DPI awareness.Now after set the DPI awareness:
Add this in your code:
import ctypes
ctypes.windll.shcore.SetProcessDpiAwareness(2) # this could only be used when your version of windows >= 8.1

Unable to put transparent PNG over a normal image Python Tkinter

So I have 2 images, 1 image is supposed to be the background and the other 1 is just an image of a character.
I am able to put one image over the other but the image has white borders even though it's a PNG file.
This is how it looks like:
This is how I want it to look like:
Here are the two separte images:

Sorry that I didnt post the images directly but I can not since I do no have 10 reputation points.
I've tried converting it to RGBA but same thing happened.
from tkinter import *
from PIL import Image
root = Tk()
root.title("Game")
background = PhotoImage(file="back.png")
backgroundlabel = Label(root, image=background)
backgroundlabel.pack()
character = PhotoImage(file="hero.png")
characterlabel = Label(root, image=character)
characterlabel.place(x=0,y=0)
root.mainloop()

You just need to use the canvas widget in Tkinter. Only the canvas widget supports transparency. This has to do with how Tkinter draws the display. As of right now, your code is just overlaying two images. Tkinter does not know how to compose them with transparency unless you use the canvas widget.
See the following code:
from tkinter import *
from PIL import Image
root = Tk()
root.title("Game")
frame = Frame(root)
frame.pack()
canvas = Canvas(frame, bg="black", width=700, height=400)
canvas.pack()
background = PhotoImage(file="background.png")
canvas.create_image(350,200,image=background)
character = PhotoImage(file="hero.png")
canvas.create_image(30,30,image=character)
root.mainloop()
All I did was download the images you provided. I did not modify the images. So, the bottom line is that you just need to use the canvas widget.
Voilà!
Note: The question asked is a duplicate of How do I make Tkinter support PNG transparency?

How to add a partially transparent image to Tkinter?

I am making a game in Tkinter and I would really like partially transparent images in the game for obvious reasons...
How would I do that? PNG doesn't allow transparency, and JPEG does allow transparency but isn't considered an 'image file'... What file type would allow that? Can I use bitmap somehow to make a JPEG useable? Thanks!
Some use info:
I started learning Python 3 months ago and am not horribly good, but I do know classes, functions, and how to make stuff in Tkinter. I also obviously know a lot more, but as I said I am not too terribly good at it. Thanks!

Tkinter does recognise .ico files, but I have never used them apart from as an icon at the top left.
I would use a GIF file, and tk.PhotoImage to display it. This does allow for transparent images to be shown:
My Proof:
The image in a tk window, but when I change the background colour to say yellow, the button background is the same as the tk window background, so it is transparent.
EDIT: HERE IS CODE
import tkinter as tk
root = tk.Tk()
image1 = tk.PhotoImage(file = "FILENAME.gif")
label1 = tk.Button(image = image1)
label1.pack()
root.mainloop()
hope that helps you.

from tkinter import *
root = Tk()
startpic = PhotoImage(file = "ddsp.gif")
startbut = PhotoImage(file = "start.gif")
helpbut = PhotoImage(file = "help.gif")
exitbut = PhotoImage(file = "exit.gif")
root.geometry("640x480")
root.title("Deep Death")
root.resizable(0,0)
starter = Label(image = startpic)
starter.pack()
start = Label(image = startbut)
start.place(x=340,y=80)
root.mainloop()
Even though the .gifs' are transparent, they are appearing with a white background.

Insert a .jpg in a canvas with tkinter and Python 3.2

So I want to put a .jpg in a canvas, all i found on internet is to use PIL but i'm using Python 3.2 so PIL doesn't work.
What can i do to insert a .jpg in a canvas with Python 3.2 ?

Just to save anyone else viewing this now from hunting around for the bits and pieces (like I just did)
As Martijn Pieters said use Pillow rather than PIL, but the code looks the same
from tkinter import Tk, Canvas
from PIL import ImageTk, Image
root = Tk()
#Create a canvas
canvas = Canvas(root, width=400, height=300)
canvas.pack()
# Load the image file
im = Image.open('test_image.jpg')
# Put the image into a canvas compatible class, and stick in an
# arbitrary variable to the garbage collector doesn't destroy it
canvas.image = ImageTk.PhotoImage(im)
# Add the image to the canvas, and set the anchor to the top left / north west corner
canvas.create_image(0, 0, image=canvas.image, anchor='nw')
root.mainloop()

PIL does work on Python 3.2; install Pillow, the friendly PIL fork.
Pillow 2.0.0 adds Python 3 support and includes many bug fixes from around the internet.

You just need to create the image in the canvas. Make sure that your image is in the same folder as your code.
image = PhotoImage (file="image.jpg")
yourcanvas.canvas.create_image (0, 0, anchor=NW, image=image, tags="bg_img")
That should do it. This will also extend the canvas to the size of the image, just to let you know. Good luck with your project!

How to put a cropped image on a Tkinter Canvas in Python

I found a lot of similar questions, but not quite the solution to this case :
I want to
Load an image file from disk
Crop it (lazy or not)
Place it on a TKinter canvas
And oh, it would even be better that step 1 would not need to be a gif-file, but even if it has to be I'll be happy. That's it..
I can load a file, I can crop it (In PIL) I can place it on a canvas (In TKinter), but I don't seem able to combine it all.. (So maybe a simple cast from PIL to TKinter is enough?) I'm a newbee in TKinter of course.

There is ImageTk module in PIL.
from Tkinter import *
from PIL import Image, ImageTk
root = Tk()
canvas = Canvas(root, width=500, height=500)
canvas.pack()
im = Image.open("image.png")
cropped = im.crop((0, 0, 200, 200))
tk_im = ImageTk.PhotoImage(cropped)
canvas.create_image(250, 250, image=tk_im)
root.mainloop()
