limit the size of a button with an image

Question

Problem:

I want to create my own widget that uses an image in a button, but the image causes the button to be way too big. How can I resize the button to the normal button size (the size of normal Text).

Code:

add = Button(master=controlfrm , image=myimagepath)
add.pack()

Result:

Goal:

I want the image to be resized to a height equal to the Entry widget.

Answer 1

Tkinter doesn't shrink or expand images. The best you can hope for is to use the zoom and subsample methods on a PhotoImage, which will allow you to change the size by a factor of 2.

If you want to use an image on a button, and you want it to be smaller, the best solution is to start with an image that is the right size.

Answer 2

You can use ImageTk.PhotoImage to resize the image and call it in a Button. Use the zoom to shrink or expand your button image.

button_image_file = "images/square-button-1.png"
button_image      = Image.open(button_image_file)
zoom = .40  # multiplier for image size by zooming -/+
pixels_x, pixels_y = tuple([int(zoom * x) for x in button_image.size])
button_image = ImageTk.PhotoImage(button_image.resize((pixels_x, pixels_y)))

button = tk.Button(root_main, text="Button", command=lambda: do_something(), font="Arial",
                    bg="#20bebe", fg="white",  image=button_image)
button.place(rely=0.01, relx=.01)

Answer 3

Try to set the width and height properties of the image, so that the image can fit to size of the button that you require.
