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()

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?
I found this code:
from PIL import Image, ImageTk
import tkinter as tk
root = tk.Tk()
img = Image.open(r"Sample.jpg")
canvas = tk.Canvas(root, width=500, height=500)
canvas.pack()
tk_img = ImageTk.PhotoImage(img)
canvas.create_image(250, 250, image=tk_img)
root.mainloop()
It displays any picture in 500x500px resolution. I tried to change it and display it in its original size:
from PIL import Image, ImageTk
import tkinter as tk
root = tk.Tk()
img = Image.open(r"D:/1.jpg")
canvas = tk.Canvas(root, width=img.width, height=img.height)
canvas.pack()
tk_img = ImageTk.PhotoImage(img)
canvas.create_image(img.width/2, img.height/2, image=tk_img)
root.mainloop()
But something went wrong and the picture with a size of 604x604px shows in a window with a size of 602x602px, but the window size is correct.
Take a look (full image).
What am I doing wrong?
P.S. Sorry for bad English.
Well, no, your first example still cuts off by a few pixels. All top level windows will have padding around their absolute borders to prevent other elements from 'bleeding' into the borders and looking unprofessional.
You are still being given a canvas of 604 pixels by 604 pixels, but the root window itself is asserting its padding. I could not find any way of removing this top level padding, and it may very well appear differently in other operating systems. A work-around could be to request a canvas size that is slightly larger than the image you would like to display.
Another issue, if you're aiming for precision, would be the line...
canvas.create_image(img.width/2, img.height/2, image=tk_img)
Which could create off-by-one errors if your width or height is an odd number. You can anchor images to the north-west corner and place them at the co-ordinates (0, 0) like such:
canvas.create_image(0, 0, anchor=tk.NW, image=tk_img)
Is there any way to import an image into python using PIL and set it as the background for a ttk mainframe that spans the entirety of a Tkinter root window? As of now I have only seen ways to do this is a Tkinter root. Also is there any way to make ttk self adjust the size of the image so that even if it's small it covers the entire screen?
So to sum up I want an image to cover the entire ttk mainframe box without messing with me putting anything else in the ttk frame.
for example
if the pic covered the entire window, a command,
ttk.Button(root, text="Hello").grid(column=0, row=0, sticky=(N,S,W,E))
would still insert a button in the mainframe. Thanks :)
You can't set an image background to a ttk frame, they don't accept image options. So you could make a ttk frame and put a label or something inside it and then have it span the frame adapting the below example.
Here's a small example demonstrating what you want. We load an image with pil, notice the image linked will be smaller (I hope) than your screensize.
So, we set the geometry of the root window to be the entire screen the image is less than this so we resize it to cover the entire width. You can override the max and min height and then set it according to this. Just a sample value. We then place the bg label and grid widgets on top of it. The label has a lower stacking order than the other widgets you will place with grid so they appear on top. Alternatively you could use a canvas, or another widget. With a canvas you'll have to use create_window to place widgets in the canvas.
import tkinter as tk
from tkinter import ttk
from PIL import Image, ImageTk
root = tk.Tk()
width, height = root.winfo_screenwidth(), root.winfo_screenheight()
#print(root.winfo_screenheight(), root.winfo_screenwidth())
root.geometry("%dx%d" % (width, height))
#URL FOR BACKGROUND

image = Image.open("background.jpg")
if image.size != (width, height):
image = image.resize((width, height), Image.ANTIALIAS)
#print("DONE RESIZING")
# image.save("background.jpg")
#print(image.size)
image = ImageTk.PhotoImage(image)
bg_label = tk.Label(root, image = image)
bg_label.place(x=0, y=0, relwidth=1, relheight=1)
bg_label.image = image
your_button = ttk.Button(root, text='This is a button')
your_button.grid()
root.mainloop()
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!
I put in a partially transparent PNG image in Tkinter and all I get is this
How do I make the dark triangle on the right clear? (like it's supposed to be)
This is python 2.6 on Windows 7, btw.
Here's an example (the PNG file example.png has lots of transparency in different places):
from Tkinter import Tk, Frame, Canvas
import ImageTk
t = Tk()
t.title("Transparency")
frame = Frame(t)
frame.pack()
canvas = Canvas(frame, bg="black", width=500, height=500)
canvas.pack()
photoimage = ImageTk.PhotoImage(file="example.png")
canvas.create_image(150, 150, image=photoimage)
t.mainloop()
You need to make sure the image has been stored as "RGBA" which is RGB with an alpha channel. You can check for that using a graphics program of your choice, or using PIL (Python Imaging Library):
import Image
im = Image.open("button.png")
print im.mode
This should print "RGBA". If not, you'll have to make sure the alpha channel is saved with the image. You'll have to consult your graphics program manual for how to do that.
