我如何在 Python 代碼（TKinter、Pillow、customtkinter）中解決這個問題

Question

我正在嘗試將圖像添加到 Customtkinter Buttom，但出現錯誤

import sqlite3
from tkinter import \*
import customtkinter
from tkinter import ttk
from PIL import Image, ImageTk

customtkinter.set_appearance_mode('dark')
customtkinter.set_default_color_theme('blue')

\#Create a Ctk instance(app)
main = customtkinter.CTk()
main.geometry("400x240")
main.resizable(width=False, height=False)

\#Username Frame
username_tittle = customtkinter.CTkLabel(master=main, text='Username:').place(relx=0.2, rely= 0.3)
username_box = customtkinter.CTkEntry(master=main, width=150)
username_box.place(relx=0.43, rely=0.3)
python_image = ImageTk.PhotoImage(Image.open('user_icon.png'), Image.ANTIALIAS, )
but = customtkinter.CTkButton(master=main, image=python_image).pack()

此代碼生成以下錯誤：

c:\\Users\\claud\\OneDrive\\Documentos\\meuusprojetos\\Login\\main.py:19: DeprecationWarning: ANTIALIAS is deprecated and will be removed in Pillow 10 (2023-07-01). Use LANCZOS or Resampling.LANCZOS instead.
python_image = ImageTk.PhotoImage(Image.open('user_icon.png'), Image.ANTIALIAS, )
CTkButton Warning: Given image is not CTkImage but \<class 'PIL.ImageTk.PhotoImage'\>. Image can not be scaled on HighDPI displays, use CTkImage instead.

self.\_image_label.configure(image=self.\_image.create_scaled_photo_image(self.\_get_widget_scaling(),
AttributeError: 'PhotoImage' object has no attribute 'create_scaled_photo_image'

有誰能夠幫我？

Answer 1

看起來您在嘗試將圖像添加到customtkinter模塊中的CTkButton小部件時遇到錯誤。

錯誤消息提到給定圖像不是CTkImage ，而是PIL.ImageTk.PhotoImage 。

要解決此問題，您可以嘗試以下操作：

使用CTkImage class 創建圖像 object 而不是PIL.ImageTk.PhotoImage class。您可以通過使用CTkImage.open()方法打開圖像文件來執行此操作，如下所示：

python_image = customtkinter.CTkImage.open('user_icon.png')

我希望這個建議對你有所幫助。

最新版本的customtkinter僅接受CTkImage作為其小部件的image選項：

...
python_image = customtkinter.CTkImage(Image.open("user_icon.png"))
customtkinter.CTkButton(master=main, image=python_image).pack()
...
