I am wondering how to create a blur transparency effect in tkinter. I already know how to add the transparency effect to the window by using
root=Tk()
root.attributes("-alpha",0.95)
But how can you add the blur part?
This service is not provided by tkinter. However you can take a screenshot of your app and blur it yourself (see for instance ImageFilter.GaussianBlur or numpy.gaussian filter).
You should use "BlurWindow" package and install it this way:
python -m pip install BlurWindow
from tkinter import *
from ctypes import windll
from BlurWindow.blurWindow import blur
root = Tk()
root.config(bg='green')
root.wm_attributes("-transparent", 'green')
root.geometry('500x400')
root.update()
hWnd = windll.user32.GetForegroundWindow()
blur(hWnd)
def color(hex):
hWnd = windll.user32.GetForegroundWindow()
blur(hWnd,hexColor=hex)
e = Entry(width=9)
e.insert(0,'#12121240')
e.pack()
b = Button(text='Apply',command=lambda:[color(e.get())])
b.pack()
root.mainloop()

I am trying to build a program which gets me an enlarged photo of the text I want, for this I decided to use tkinter, win32gui and pygetwindow modules after taking some tips from already asked problems on stack overflow am having the following problems:
(1)I don't know how to get the hwnd value of the tkinter window which I created.
(2)I can't get hwnd value even if I know how to get it as the window is created after the complete code has run.
So please suggest me solutions to the problem
This is my code:
from tkinter import *
import win32gui
import pygetwindow as gw
#making the tkinter window
root = Tk()
root.title('DaysLeft')
#getting all the windows with their hwnd values
hwnd=gw.getAllWindows()
print(hwnd)
win32gui.SetForegroundWindow(hwnd)
bbox = win32gui.GetWindowRect(hwnd)
img = ImageGrab.grab(bbox)
img.show()
mainloop()
The above code gives error below as expected:.
line 26, in <module>
win32gui.SetForegroundWindow(hwnd)
TypeError: The object is not a PyHANDLE object
You can use PIL for taking a screenshot and win32gui or pygetwindow to get windows location.
Install PIL by saying
pip install Pillow
then your working code would be:
from tkinter import *
from win32gui import FindWindow, GetWindowRect
import pygetwindow as gw
from PIL import ImageGrab
def ss():
win = gw.getWindowsWithTitle('DaysLeft')[0]
winleft = win.left+9
wintop = win.top+38 #change 38 to 7 to not capture the titlebar
winright = win.right-9
winbottom = win.bottom-9
final_rect = (winleft,wintop,winright,winbottom)
img = ImageGrab.grab(final_rect)
img.save('Required Image.png')
#making the tkinter window
root = Tk()
root.title('DaysLeft')
root.after(3000,ss)
root.mainloop()
Why am i subtracting some amount from the pixels? its because, windows has decorations like drop shadow effect to the windows, which are also part of the windows and will be included in the screenshot, so i used this to get rid of those extra pixels.
Or if your still reluctant on using win32gui then, change the function to:
from win32gui import FindWindow, GetWindowRect
from PIL import ImageGrab
......
def ss():
win = FindWindow(None, 'DaysLeft')
rect = GetWindowRect(win)
list_rect = list(rect)
list_frame = [-9, -38, 9, 9] #change -38 to -7 to not capture the titlebar
final_rect = tuple((map(lambda x,y:x-y,list_rect,list_frame))) #subtracting two lists
img = ImageGrab.grab(bbox=final_rect)
img.save('Image.png')
What is after method? It just calls the function after 3000 ms, i.e, 3 seconds. We are basically giving the system some time to build the GUI and capture screenshot.
Hope it helped, do let me know if any errors or doubts.
Cheers
I am trying to create a translucent window in Tkinter like the one in windows 11
How to do this? If we cannot do this can we capture a part of a screen and blur it using cv2 and use it as a continuously updating background?
No, this is not directly possible with tkinter. But:
If you use PIL, you can get the location of the window, and then take a screenshot, then blur it and then make it your app background. But this wont work if user tries to move/resize the application. But here is a rough code:
from tkinter import *
from PIL import ImageTk, ImageGrab, ImageFilter # pip install Pillow
root = Tk()
root.overrideredirect(1) # Hide the titlebar etc..
bg = Canvas(root)
bg.pack(fill='both',expand=1)
root.update()
# Get required size and then add pixels to remove title bar and window shadow
left = root.winfo_rootx()
top = root.winfo_rooty()
right = left + root.winfo_width()
bottom = top + root.winfo_height()
root.withdraw() # Hide the window
img = ImageGrab.grab((left,top,right,bottom)) # Get the bg image
root.deiconify() # Show the window
img = img.filter(ImageFilter.GaussianBlur(radius=5)) # Blur it
img = ImageTk.PhotoImage(img)
bg.create_image(0,0, image=img, anchor='nw') # Show in canvas
label = Label(root,text='This is a translucent looking app')
bg.create_window(bg.winfo_width()/2,bg.winfo_height()/2,window=label) # Position in the center
root.mainloop()
Output with tkinter:
tkinter is not the best choice if you are trying to go for a modern look, use PyQt and check qtacrylic
Output with PyQt:
For live blur (native Windows blur) use "BlurWindow":

e = Entry(width=9)
e.insert(0,'#12121240')

b.pack()

Working in a EXE file with background and Icon embed, I read some ideas about to use img2py in order to create module.py that can be imported into the EXE with pyinstaller.
I successfully create the imagebg.py (BG2.png Background) and imageico.py (ico2.ico Icon) modules using img2py. But there is no example or way to set that images into the modules in the tkinter label as background and the icon into the code.
Please anybody can help me.
Main code where must be imported BG ad ICON modules and use them as background and Icon images for tkinter GUI
#Main code GUI tkinter
import imagebg #from here we must import PNG_File.png for Background
import imageico #from here we must import ICO_File.ico for Icon
import wx #from img2py installation
from tkinter import *
root=Tk()
#set windows size
root.resizable(width=False, height=False)
root.geometry("925x722")
#set title
root.title("SOFT1)")
#frame 1
f1=Frame(root, width=345,height=475,bg="light
grey",highlightbackground="black",highlightthickness=4)
f1.place(x=20,y=235)
#set a image as BG
Logo=PhotoImage(file="PNG_File.png")
lab6=Label(root, image=Logo)
lab6.place(x=0, y=0)
#set a image as ICON
root.iconbitmap("ICO_File.ico")
mainloop()

Please any idea of how to use the modules as images for background and icon in the main code GUI Tkinter
You need to convert the wx.Image to PIL compatible image if you want to use it in tkinter application.
Below is an example based on your posted code:
import tkinter as tk
from PIL import Image, ImageTk
import imagebg
import imageico
# function to convert a wx.Image to PIL.ImageTk.PhotoImage
def wx2pil(wx_image):
image = wx_image.Image
w, h = image.GetWidth(), image.GetHeight()
data = image.GetData()
img = Image.frombytes('RGB', (w, h), bytes(data))
return ImageTk.PhotoImage(img)
root = tk.Tk()
root.resizable(False, False)
root.geometry('925x722')
root.title('SOFT1')
# use iconphoto() instead of iconbitmap()
root.iconphoto(False, wx2pil(imageico.ico2))
#set a image as BG
logo = wx2pil(imagebg.BG2)
tk.Label(root, image=logo).place(x=0, y=0)
#frame 1
f1 = tk.Frame(root, width=345, height=475, bg='lightgray', highlightbackground='black', highlightthickness=4)
f1.place(x=20, y=235)
root.mainloop()
Note that I use wxPython v4.1.0.
As it depends on wxPython, why don't you use wxPython for the GUI directly instead of tkinter?
I have been trying to show an image for a game but it doesn't show can i please have some help?
I've tried to download PIL but it doesn't work with python 3.
from tkinter import *
canvas = Canvas(width=500, height=500)
canvas.pack(expand=YES, fill=BOTH)
Logo = PhotoImage('photo.gif')
canvas.create_image(50, 10, image=Logo)
label = Label(image=Logo)
label.image = Logo
label.pack()
mainloop()
If you dont tell PhotoImage() what the first argunent is, it will assume its the widget's name. To get it to load a file you have to explicitly tell it that it is a file:
Logo = PhotoImage(file='photo.gif')
Python 3.6.4 with Pillow 5.2.0
You can use: python -m pip install Pillow
Here is an example of how to use PIL with tkinter
from PIL import Image, ImageTk
import tkinter as tk
root = tk.Tk()
img = Image.open("test.png")
tk_image = ImageTk.PhotoImage(img)
label =tk.Label(root, image=tk_image)
label.pack()
root.mainloop()
I made a GUI with few buttons and I want to change the gray background to an image.
my code looks like this:
from tkinter import *
from urlread import givenumbers # my function
""" Setting The Main GUI """
GUI = Tk()
GUI.title('Check GUI')
GUI.iconbitmap('test.ico')
GUI.geometry("400x400")
background_image=PhotoImage('pic.jpg')
background_label = Label(GUI, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)
""" Reading Images For Buttons """
A_Im = PhotoImage(file='A.gif')
""" Creating Buttons """
# A Button
A_Button = Button(GUI, image=A_Im, command=givenumbers)
A_Button.grid(column=0, row=1)
GUI.mainloop()
The code runs without error but the background is still gray without any effect.
The problem is in the line background_image=PhotoImage('pic.jpg'). The PhotoImage class only supports GIF-files, which means that it cannot read the file you're specifying. You should try something like this:
#Python 2.7
import Tkinter as tk
from PIL import Image, ImageTk
window = tk.Tk()
image = Image.open('image.jpg')
photo_image = ImageTk.PhotoImage(image)
label = tk.Label(window, image = photo_image)
label.pack()
# Python 3
import tkinter as tk
from PIL import Image, ImageTk
window = tk.Tk()
image = Image.open('image.jpg')
photo_image = ImageTk.PhotoImage(image)
label = tk.Label(window, image = photo_image)
label.pack()
The Image class from the PIL module supports a variety of formats, among which jpeg and png. You can install the PIL module by running pip install pillow in a command prompt or terminal.
If you want to put the widgets on top of the Label, you could indeed using grid to get them on top of each other, but using a Canvas would probably be easier. You can find more about the Canvas widget here.
This can be done without pil also:
from tkinter import *
import tkinter as ttk
""" Setting The Main GUI """
GUI = Tk()
F1=Frame(GUI)
F1=Frame(GUI,width=400,height=450)
F1.place(height=7000, width=4000, x=100, y=100)
F1.config()
F1.grid(columnspan=10,rowspan=10)
F1.grid_rowconfigure(0,weight=1)
F1.grid_columnconfigure(0,weight=1)
photo=PhotoImage(file="C:\\Users\\HOME\\Desktop\\Eshita\\12th\\computer
\\python\\GUI\\math3.gif")
label = Label(GUI,image = photo)
label.image = photo # keep a reference!
label.grid(row=0,column=0,columnspan=20,rowspan=20)
b=ttk.Button(GUI,text="Start")
b.grid(row=8,column=8)
GUI.mainloop()
