使图片适合全屏窗口

Question

我正在尝试让图片适合我创建的全屏窗口的范围。使用此代码：

import sys
import random
import tkinter as tk
from tkinter import *
from PIL import Image, ImageTk

window = tk.Tk()
width = window.winfo_screenwidth()
height = window.winfo_screenheight()
window.geometry("%dx%d" % (width, height))
window.title("War of the Ring")

def CloseProgram():
    window.destroy()
    window.quit()

def PlayMainGame():
    #Destroy widgets and title
    Title.destroy()
    NewGameButton.destroy()
    LoadGameButton.destroy()
    OptionsButton.destroy()
    global ResizedBoardImage
    canvas = Canvas(window, width = width, height = height)
    canvas.pack()
    BoardImage = Image.open("Middle Earth Map.jpg")
    ResizedBoardImage = BoardImage.resize((width, height), )
    ResizedBoardImage = ImageTk.PhotoImage(BoardImage)
    canvas.create_image(10,10, anchor = NW, image = ResizedBoardImage)

` 我在照片中得到了结果，大约四分之一的图像填满了整个屏幕。 shell 中不会弹出任何警告或错误。不知道我做错了什么。

当我期望图像适合窗口屏幕时，我得到了照片中的结果，大约四分之一的图像填满了整个屏幕。

shell 中不会弹出任何警告或错误。不知道我做错了什么。

Answer 1

描述： 问题出在您的代码中：

width = window.winfo_screenwidth()
height = window.winfo_screenheight()

您正在根据您的显示器定义 tkinter 窗口宽度和高度。

例如，如果您的 Windows 分辨率为

1920x1080

，则此片段中的宽度

width = window.winfo_screenwidth()

将定义为 1920，此片段中的高度

height = window.winfo_screenheight()

将定义为 1080。

问题： tkinter 窗口太大了，如果您减小 tkinter 窗口的高度和宽度，它会扩展到屏幕之外，那么它将适合您。

解决方案： 考虑到你的决心是

1920x1080

:

import sys
import random
import tkinter as tk
from tkinter import *
from PIL import Image, ImageTk

window = tk.Tk()
width = 1600
height = 900
window.geometry("%dx%d" % (1600, 900))
window.title("War of the Ring")

def CloseProgram():
    window.destroy()
    window.quit()

def PlayMainGame():
    #Destroy widgets and title
    Title.destroy()
    NewGameButton.destroy()
    LoadGameButton.destroy()
    OptionsButton.destroy()
    global ResizedBoardImage
    canvas = Canvas(window, width = width, height = height)
    canvas.pack()
    BoardImage = Image.open("Middle Earth Map.jpg")
    ResizedBoardImage = BoardImage.resize((width, height), )
    ResizedBoardImage = ImageTk.PhotoImage(BoardImage)
    canvas.create_image(10,10, anchor = NW, image = ResizedBoardImage)

考虑到你的决心是

1600x900

：

import sys
import random
import tkinter as tk
from tkinter import *
from PIL import Image, ImageTk

window = tk.Tk()
width = 1280
height = 720
window.geometry("%dx%d" % (1600, 900))
window.title("War of the Ring")

def CloseProgram():
    window.destroy()
    window.quit()

def PlayMainGame():
    #Destroy widgets and title
    Title.destroy()
    NewGameButton.destroy()
    LoadGameButton.destroy()
    OptionsButton.destroy()
    global ResizedBoardImage
    canvas = Canvas(window, width = width, height = height)
    canvas.pack()
    BoardImage = Image.open("Middle Earth Map.jpg")
    ResizedBoardImage = BoardImage.resize((width, height), )
    ResizedBoardImage = ImageTk.PhotoImage(BoardImage)
    canvas.create_image(10,10, anchor = NW, image = ResizedBoardImage)

结论： 减小 tkinter 窗口的大小，不要保持与原始分辨率相同，因为窗口小部件也占用了窗口以及 tkinter 窗口任务栏的一些空间，这使得窗口变得比预期的宽度和高度更大.
