Tkinter images and geometry creation - python

I've tried to do a star fractal drawing a star using tkinter and putting an image as a background.
from tkinter import *
from PIL import ImageTk, Image
import tkinter as tk
app = Tk()
app.title("Welcome")
img =Image.open('C:\\Users\\Stefa\\Downloads\\galaxy.jpeg')
bg = ImageTk.PhotoImage(img)
canvas_width=800
canvas_height=800
master = tk.Tk()
label = Label(app, image=bg)
label.place(x = 0,y = 0)
label2 = Label(app, text = "WELCOME TO OUR GALAXY",
font=("Times New Roman", 24))
label2.pack(pady = 50)
app.geometry(f"{canvas_width}x{canvas_height}")
can_widgt=Canvas(app, width=canvas_width, height= canvas_height)
can_widgt.pack()
points=[200,20,80,396,380,156,20,156,320,396]
can_widgt.create_polygon(points, outline='red',fill='cyan', width=6)
app.mainloop()
That's the code
However when i run it i want the star to be upon the background image. Any solutions for this ? Thanks

You need to create the image as a canvas object rather than as a label.
For example, this add the image to the top-left corner of the canvas, with the drawing on top of it:
can_widgt.create_image(0, 0, anchor="nw", image=bg)

I'm trying to make my GUI window's dynamic, but there is an error i can't figured out that when i run the program, the program want to run but it still not dynamic and in the terminal, there is an error says AttributeError: 'PhotoImage' object has no attribute 'read'.

python3 tkinter GUI with clickable transparent images

I have made a background for my GUI in inkscape and have managed to add a transparent image over the top to use as buttons but cant figure out how to make them run a subroutine (nav) when clicked. I either need an image with transparency over the top of my background that I can click or a completely see through rectangle that I can position over a button drawn on the background image in inkscape. I'm on Ubuntu if it matters.
from tkinter import *
from PIL import ImageTk, Image
import sys
root = Tk ()
root.title('GUI')
root.geometry("1000x564")
root.attributes('-zoomed', True)
root.attributes("-type", "splash")
#define image
bg = ImageTk.PhotoImage(file="BACKGROUND.png")
#create canvas
my_canvas = Canvas(root, width=800, height=500)
my_canvas.pack(fill="both", expand=True)
my_canvas.create_image(0,0, image=bg, anchor = NW)
def nav():
print ("navigation")
#creating button which supports png transparency
#button = PhotoImage(file="button2.png")
#my_canvas.create_image(260,-70, anchor=NW, image=button, state='normal', )
buttonImage = ImageTk.PhotoImage(Image.open("button.png"))
button = my_canvas.create_image(50, 50, image=buttonImage)
my_canvas.tag_bind(Button, "<Button-1>", nav())
def resizer(e):
global bg1, resized_bg, new_bg
# open image
bg1 = Image.open("BACKGROUND.png")
# resize
resized_bg =bg1.resize((e.width, e.height), Image.ANTIALIAS)
#DEFINE IMAGE AGAIN
new_bg =ImageTk.PhotoImage(resized_bg)
#add back to the canvas
my_canvas.create_image(0,0, image=new_bg, anchor = NW)
# my_canvas.create_image(260,-70, anchor=NW, image=button, state='normal', )
button = my_canvas.create_image(50, 50, image=buttonImage)
def close(e):
root.destroy()
root.bind('<Configure>', resizer)
root.bind('<Escape>', close)
root.mainloop()
when calling function with my_canvas.tag_bind(button, "<Button-1>", nav) nav(root) is actually being called when clicked so def nav(root): has to be used for the sub routine to run correctly.

Is it possible to give slideDown transition on Image in Tkinter?

Just like how we give effects on image in Jquery using the code
$('.img').slideDown('fast', 'linear', function() {});
Is there any way to give slideDown effect on canvas image in tkinter ?
This is my code.
from tkinter import *
from PIL import Image, ImageTk
root = Tk()
frame = Frame(root)
frame.pack()
canvas = Canvas(frame, width=300, height=300, bd=0, highlightthickness=0, relief='ridge')
canvas.pack()
background = PhotoImage(file="background.png")
canvas.create_image(300,300,image=background)
my_pic = PhotoImage(file="start000-befored.png") #and on this image, I want to give slidedown effect.
canvas.create_image(50,50,image=my_pic, anchor=NW)
root.mainloop()

tkinter background image in Frame

I want to put a background image in a Frame, this is the code that I'm trying to run without success.
import tkinter as tk
from tkinter import *
root = tk.Tk()
F1 = Frame(root)
F1.grid(row=0)
photo = PhotoImage(file="sfondo.png")
label = Label(F1, image=photo)
label.image = photo
label.place(x=0, y=0)
b = tk.Button(label, text="Start")
b.grid(row=8, column=8)
root.mainloop()
If I run the code as this, only a little point in the top left corner is displayed (the frame without nothing in, even if I placed the label inside of it). If I replace the label parent with root, it displays the button with a little part of the image as backgound (only the perimeter of the button is colored for a few pixels). However what I want is a full displayed background image in the frame where I can put the widgets that I want.
I tried to with the place method as this and PIL module
import tkinter as tk
from tkinter import *
from PIL import Image, ImageTk
root = tk.Tk()
F1 = Frame(root)
F1.grid(row=0)
image = Image.open("sfondo.png")
render = ImageTk.PhotoImage(image)
img = tk.Label(F1, image=render)
img.image = render
img.place(x=0, y=40)
b = tk.Button(img, text="Start")
b.grid(row=8, column=8)
root.mainloop()
Here more or less I'm having the same problems, if I set the parent of the label to root, the button is displayed with the perimeter coloured.
If I set the parent to F1 nothing happens and in both cases if I set the parent as root and remove the button, the image is fully displayed.
But what I want is that the image is fully displayed in the frame and after diplay on the background image the widgets.
You could put an image on a Canvas, and then place a Button on that by putting it inside a Canvas window object which can hold any Tkinter widget.
Additional widgets can be added in a similar fashion, each inside its own Canvas window object (since they can hold only a single widget each). You can workaround that limitation by placing a Frame widget in the Canvas window, and then putting other widgets inside it.
Here's an example showing how to display a single Button:
from PIL import Image, ImageTk
import tkinter as tk
IMAGE_PATH = 'sfondo.png'
WIDTH, HEIGTH = 200, 200
root = tk.Tk()
root.geometry('{}x{}'.format(WIDTH, HEIGHT))
canvas = tk.Canvas(root, width=WIDTH, height=HEIGTH)
canvas.pack()
img = ImageTk.PhotoImage(Image.open(IMAGE_PATH).resize((WIDTH, HEIGTH), Image.ANTIALIAS))
canvas.background = img # Keep a reference in case this code is put in a function.
bg = canvas.create_image(0, 0, anchor=tk.NW, image=img)
# Put a tkinter widget on the canvas.
button = tk.Button(root, text="Start")
button_window = canvas.create_window(10, 10, anchor=tk.NW, window=button)
root.mainloop()

Edit
While I don't know of a way to do it in Frame instead of a Canvas, you could derive your own Frame subclass to make adding multiple widgets easier. Here's what I mean:
from PIL import Image, ImageTk
import tkinter as tk
class BkgrFrame(tk.Frame):
def __init__(self, parent, file_path, width, height):
super(BkgrFrame, self).__init__(parent, borderwidth=0, highlightthickness=0)
self.canvas = tk.Canvas(self, width=width, height=height)
self.canvas.pack()
pil_img = Image.open(file_path)
self.img = ImageTk.PhotoImage(pil_img.resize((width, height), Image.ANTIALIAS))
self.bg = self.canvas.create_image(0, 0, anchor=tk.NW, image=self.img)
def add(self, widget, x, y):
canvas_window = self.canvas.create_window(x, y, anchor=tk.NW, window=widget)
return widget
if __name__ == '__main__':
IMAGE_PATH = 'sfondo.png'
WIDTH, HEIGTH = 350, 200
root = tk.Tk()
root.geometry('{}x{}'.format(WIDTH, HEIGTH))
bkrgframe = BkgrFrame(root, IMAGE_PATH, WIDTH, HEIGTH)
bkrgframe.pack()
# Put some tkinter widgets in the BkgrFrame.
button1 = bkrgframe.add(tk.Button(root, text="Start"), 10, 10)
button2 = bkrgframe.add(tk.Button(root, text="Continue"), 50, 10)
root.mainloop()
Result:
Update
It recently dawned on me that there actually is a simpler way to do this than creating a custom Frame subclass as shown in my previous edit above. The trick is to place() a Label with image on it in the center of the parent Frame — you are then free to use other geometry managers like pack() and grid() as you normally would — as illustrated in the sample code below. Not only is it less complicated, it's also a more "natural" way of adding widgets than needing to call a non-standard method such as add().
from PIL import Image, ImageTk
import tkinter as tk
IMAGE_PATH = 'sfondo.png'
WIDTH, HEIGHT = 250, 150
root = tk.Tk()
root.geometry('{}x{}'.format(WIDTH, HEIGHT))
# Display image on a Label widget.
img = ImageTk.PhotoImage(Image.open(IMAGE_PATH).resize((WIDTH, HEIGHT), Image.ANTIALIAS))
lbl = tk.Label(root, image=img)
lbl.img = img # Keep a reference in case this code put is in a function.
lbl.place(relx=0.5, rely=0.5, anchor='center') # Place label in center of parent.
# Add other tkinter widgets.
button = tk.Button(root, text="Start")
button.grid(row=0, column=0)
button = tk.Button(root, text="Continue")
button.grid(row=0, column=1, padx=10)
root.mainloop()
Result#2
P.S. You can download a copy of the sfondo.png background image from here.

How can I set an image as a background in tkinter? [duplicate]

#import statements
from Tkinter import *
import tkMessageBox
import tkFont
from PIL import ImageTk,Image
Code to import image:
app = Tk()
app.title("Welcome")
image2 =Image.open('C:\\Users\\adminp\\Desktop\\titlepage\\front.gif')
image1 = ImageTk.PhotoImage(image2)
w = image1.width()
h = image1.height()
app.geometry('%dx%d+0+0' % (w,h))
#app.configure(background='C:\\Usfront.png')
#app.configure(background = image1)
labelText = StringVar()
labelText.set("Welcome !!!!")
#labelText.fontsize('10')
label1 = Label(app, image=image1, textvariable=labelText,
font=("Times New Roman", 24),
justify=CENTER, height=4, fg="blue")
label1.pack()
app.mainloop()
This code doesn't work. I want to import a background image.
One simple method is to use place to use an image as a background image. This is the type of thing that place is really good at doing.
For example:
background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)
You can then grid or pack other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.
Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:
background_label.image = background_image
A simple tkinter code for Python 3 for setting background image .
from tkinter import *
from tkinter import messagebox
top = Tk()
C = Canvas(top, bg="blue", height=250, width=300)
filename = PhotoImage(file = "C:\\Users\\location\\imageName.png")
background_label = Label(top, image=filename)
background_label.place(x=0, y=0, relwidth=1, relheight=1)
C.pack()
top.mainloop
You can use this:
root.configure(background='your colour')
Example:-
import tkinter
root=tkiner.Tk()
root.configure(background='pink')
