Tkinter 图像透明度 [英] Tkinter Image transparency

问题描述

所以我有 2 张图像要显示在彼此之上.顶部的图像应具有透明度，以便底部的图像可见.

So I have 2 images that I would like to display on top of each other. The image on top should have transparency so that the one on the bottom is visible.

这是我目前的代码:

from Tkinter import *
import ttk
from PIL import Image, ImageTk

root = Tk()

face = Image.open("faces/face.gif")
eyes = Image.open("faces/eyes1.png")
face = face.convert("RGBA")
eyes = eyes.convert("RGBA")
facedatas = face.getdata()
eyesdatas = eyes.getdata()

newData = []
for item in eyesdatas:
    if item[0] == 255 and item[1] == 255 and item[2] == 255:
        newData.append((255, 255, 255, 0))
    else:
        newData.append(item)

eyes.putdata(newData)
eyes.save("eyes0.png", "PNG")

facepic = ImageTk.PhotoImage(face)
eyespic = ImageTk.PhotoImage(eyes)

label1 = Label(image=facepic)
label1.image = facepic
label1.grid(row = 0, column = 0)

label2 = Label(image=eyespic)
label2.image = eyespic
label2.grid(row = 0, column = 0)

root.mainloop()

这是我运行它时得到的:

And here is what I get when I run it:

当我想获得这个时:

脸在下，眼睛在上.

推荐答案

试试这个

from PIL import Image, ImageTk
from Tkinter import Tk, Label

root = Tk()

def RBGAImage(path):
    return Image.open(path).convert("RGBA")

face = RBGAImage("faces/face.gif")
eyes = RBGAImage("faces/eyes1.png")

face.paste(eyes, (0, 0), eyes)

facepic = ImageTk.PhotoImage(face)

label1 = Label(image=facepic)
label1.grid(row = 0, column = 0)

root.mainloop()

我没有你的两个源图像，所以我不能确定它是否适用于它们.如果有任何问题，请提供两者的原件.

I do not have both your source images, so I can not be sure it will work with them. Please provide the originals of both if there is any issue.
