python - 没有背景 tkinter 的标签

Question

我正在制作一个带有背景图像和三个标签的 tkinter 应用程序。

我遇到的问题是这些标签有白色背景，我不希望这样。我想制作一个没有背景的“png”标签。

首先，我试图把这行代码：

raiz.wm_attributes('-transparentcolor' , raiz["bg"])

但它没有用，从字面上看，标签是一个洞。

然后我搜索了一个解决方案，我发现制作没有背景的标签的最佳方法是使用画布，但是有更多的错误，但是，我认为这是解决方案，但我不知道该怎么做。

这是我的代码：

from tkinter import *
import winsound
from winsound import *
from tkinter import messagebox
import time

#creamos la ventana

raiz=Tk()

raiz.wm_attributes('-transparentcolor', raiz['bg'])

raiz.title("MYRIAD ALLIANCE: ORIGINS")
raiz.geometry("900x550")
raiz.resizable(0,0)
raiz.iconbitmap('descarga.ico')
#winsound.PlaySound('C:\\Users\\shado\\Downloads\\pygame\\MY\\dark.wav', winsound.SND_ALIAS | winsound.SND_ASYNC)

#----------------------aa
def ventanas(frame):
    frame.tkrise()

def jugar():
    messagebox.showinfo("Próximamente...", "Esta opción estará disponible próximamente...")

def quitar():
    if messagebox.askokcancel("Saliendo...", "¿Estas seguro de que quieres salir?"):
        raiz.destroy()

def clickDerecho(event):
    jugar()

def clickDerecho2(event):
    quitar()

#frames--------------------------------------------------------------------

frameJugar = Frame()

fondo = PhotoImage(file= r'background.png')
background_label = Label(raiz, image=fondo)
background_label.place(x=0, y=0, relwidth=1, relheight=1)


texto = Label(raiz, text="JUGAR" ,bd=0, font=("COMIC SANS MS", 30, "italic"), fg="#00deff", cursor="hand2")
texto.bind("<Button-1>", clickDerecho)
texto.place(x=100, y=196)

texto2 = Label(raiz, text="TUTORIAL" ,bd=0, font=("COMIC SANS MS", 30, "italic"), fg="#00deff", cursor="hand2")
texto2.bind("<Button-1>", clickDerecho)
texto2.place(x=100, y=306)

texto3 = Label(raiz, text="SALIR" ,bd=0, font=("COMIC SANS MS", 30, "italic"), fg="#00deff", cursor="hand2")
texto3.bind("<Button-1>", clickDerecho2)
texto3.place(x=100, y=416)

#-----------------------------------------------------------------ejecutamos la ventana

raiz.protocol("WM_DELETE_WINDOW", quitar)
raiz.mainloop()

这是我得到的结果：

编辑：现在我正在使用一些代码进行测试，如下所示：

from tkinter import *
import winsound
from winsound import *
from tkinter import messagebox
import time


#window--------------------------------------------------------------------------------
raiz=Tk()
raiz.title("MYRIAD ALLIANCE: ORIGINS")
raiz.geometry("900x550")
raiz.resizable(0,0)
raiz.iconbitmap(r"C:\Users\shado\Desktop\Myadorigins\descarga.ico")
#winsound.PlaySound('C:\\Users\\shado\\Downloads\\pygame\\MY\\dark.wav', winsound.SND_ALIAS | winsound.SND_ASYNC)

fondo = PhotoImage(file= r'C:\Users\shado\Desktop\Myadorigins\background.png')
bg = Label(raiz, image=fondo)
bg.place(x=0, y=0)

x = 40  # Horizontal position in pixels.
y = 100 # Vertical position in pixels.
dx = 80 # Horizontal size in pixels.
dy = 30
#functions---------------------------------------------------------------------------------------

def subimage(src, left, top, right, bottom):
    dst = PhotoImage()
    dst.tk.call(dst, 'copy', src, '-from',
                left, top, right, bottom, '-to', 0, 0)
    return dst

#images--------------------------------------------------------------------
label_bg = subimage(fondo, x-2, y-2, x+dx, y+dy)

info = Label(raiz, text='Beer', bd=0, height=dy-1, width=dx-1,
             image=label_bg, compound='center')
info.place(x=x, y=y)    # Use place() to stack on top of bg image.


#-----------------------------------------------------------------ejecutamos la ventana

raiz.mainloop()

但是，“啤酒”文字没有出现，截图： 截图

这可以改进，但这里有一个一般想法的说明：从背景图像中剪下较小的图像并将它们用作标签中的背景。

import tkinter as tk

root = tk.Tk()

# Create bg image and place it on root window.
bgi = tk.PhotoImage(file='pilner.png')
bg = tk.Label(root, image=bgi)
bg.place(x=0, y=0)

# Adjust window to fit background image
root.geometry('{}x{}+0+0'.format(bgi.width(), bgi.height()))

# Image dimensions for label. Set these to contain the text size. 
x = 40  # Horizontal position in pixels.
y = 300 # Vertical position in pixels.
dx = 200 # Horizontal size in pixels.
dy = 50 # Vertical size in pixels.

# Function to copy a subimage from bg image at coordinates.
# Can't remember where I got this snippet. Pillow should work also.
def subimage(src, left, top, right, bottom):
    dst = tk.PhotoImage()
    dst.tk.call(dst, 'copy', src, '-from',
                left, top, right, bottom, '-to', 0, 0)
    return dst

# Create label bg image from root window bg image.
label_bg = subimage(bgi, x-2, y-2, x+dx, y+dy)

# For some reason there is a border around the label if I don't
# set height and width. 
info = tk.Label(root, text='Beer', bd=0, height=dy-1, width=dx-1, 
                           fg='white', font=(None, 50),
                           image=label_bg, compound='center')
info.place(x=x, y=y)    # Use place() to stack on top of bg image. 

root.mainloop()
