How to Use Bitmap images in Button in Tkinter?

Last Updated : 13 Jan, 2021

Prerequisite: Python GUI – tkinter

Python offers multiple options for developing GUI (Graphical User Interface). Out of all the GUI methods, tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python.

A bitmap is an array of binary data representing the values of pixels in an image. A GIF is an example of a graphics image file that has a bitmap.

To create a bitmap image ‘bitmap’ attribute of the button() function is used display. It can take the following values:

error
gray75
gray50
gray25
gray12
hourglass
info
questhead
question
warning

Syntax:

Button(…, bitmap=”<value>”)

Approach 1:

Import module
Create object
Create buttons
Execute code

Program:

Python3

# Import Module
from tkinter import *
  
# Create Objects
root = Tk()
  
# Buttons
Button(root, relief=RAISED, bitmap="error").pack(pady=10)
Button(root, relief=RAISED, bitmap="hourglass").pack(pady=10)
Button(root, relief=RAISED, bitmap="info").pack(pady=10)
Button(root, relief=RAISED, bitmap="question").pack(pady=10)
Button(root, relief=RAISED, bitmap="warning").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray75").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray50").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray25").pack(pady=10)
Button(root, relief=RAISED, bitmap="gray12").pack(pady=10)
Button(root, relief=RAISED, bitmap="questhead").pack(pady=10)
  
# Execute Tkinter
root.mainloop()

Output:

Approach 2:

In this method, we will create a list of bitmaps and iterate through all bitmaps while passing them to button() function.

Import module
Create object
Create bitmap list
Iterate through the list
Create buttons while iterating
Execute code

Program:

Python3

# Import Module
from tkinter import *
  
# Create Objects
root = Tk()
  
# Create Bitmaps List
bitmaps = ["error",
           "gray75",
           "gray50",
           "gray25",
           "gray12",
           "hourglass",
           "info",
           "questhead",
           "question",
           "warning"]
  
# Iterate through all bitmap list
for bit in bitmaps:
    Button(root, relief=RAISED, bitmap=bit).pack(pady=10)
  
# Execute Tkinter
root.mainloop()
