How do I make Tkinter support PNG transparency?
Here's an example (the PNG file example.png has lots of transparency in different places):
from Tkinter import Tk, Frame, Canvasimport ImageTkt = Tk()t.title("Transparency")frame = Frame(t)frame.pack()canvas = Canvas(frame, bg="black", width=500, height=500)canvas.pack()photoimage = ImageTk.PhotoImage(file="example.png")canvas.create_image(150, 150, image=photoimage)t.mainloop()You need to make sure the image has been stored as "RGBA" which is RGB with an alpha channel. You can check for that using a graphics program of your choice, or using PIL (Python Imaging Library):
import Imageim = Image.open("button.png")print im.modeThis should print "RGBA". If not, you'll have to make sure the alpha channel is saved with the image. You'll have to consult your graphics program manual for how to do that.
