python - Tkinter - 如何将文本更改为图像？

Question

让我们以此作为示例程序:

from tkinter import *
import random
win = Tk()
win.geometry('200x200')

alphabets = ["A", "B", "C"]
rand_alpha = random.choice(alphabets)

lbl = Label(win, font = 'Ariel 30',text = rand_alpha)
lbl.pack()

win.mainloop()

在上面的程序中，我想将“rand_alpha”的文本更改为图像文件，以便我可以使用 PIL 来修改它。用python可以吗？

您可以使用ImageDraw来创建您想要的图像:

from tkinter import *
import random
from PIL import Image, ImageTk, ImageDraw, ImageFont

win = Tk()
win.geometry('200x200')

alphabets = ["A", "B", "C"]
rand_alpha = random.choice(alphabets)

image = Image.new('RGB', (200, 200), (255, 255, 255))  # adjust the size to what you want
draw = ImageDraw.Draw(image)
font = ImageFont.truetype('arial.ttf', size=128) # adjust the font and size to what you want
w, h = draw.textsize(rand_alpha, font=font)
draw.text(((200-w)//2, (200-h)//2), font=font, text=rand_alpha, fill='black')
tkimage = ImageTk.PhotoImage(image)

lbl = Label(win, image=tkimage)
lbl.pack()

win.mainloop()
