How to use Bitmap images in Button in Tkinter?

In Tkinter, we can create and customize buttons using images. These images can be uploaded by using the Python PhotoImage(file) function.

However, PhotoImage() supports only a few image types such as PNG, PPM, and GIF. In addition, we can create buttons using BitMap images too. A bitmap image is nothing but a set of dots aligned in a matrix which represents a pixel of the image. The following types of bitmap attributes are available in Tkinter,

• "error"

• "gray75"

• "gray50"

• "gray25"

• "gray12"

• "hourglass"

• "info"

• "questhead"

• "question"

• "warning"

Example

from tkinter import *

#Create an instance of tkinter frame

win = Tk()
win.geometry("700x300")
win.resizable(0,0)

Button(win, relief=RAISED, bitmap="info").pack(pady=10)
Button(win, relief=RAISED, bitmap="gray50").pack(pady=10)
Button(win, relief=RAISED, bitmap="gray25").pack(pady=10)
Button(win, relief=RAISED, bitmap="gray12").pack(pady=10)
Button(win, relief=RAISED, bitmap="questhead").pack(pady=10)
win.mainloop()

Output

Running the above code will create bitmap buttons as the following,
