用Python创建一个 Sideshow 应用程序

在本文中,我们将创建一个幻灯片应用程序,即无需手动更改或单击即可查看下一张图像。

所需模块:

  • Tkinter: tkinter 包(“Tk 接口”)是 Tk GUI 工具包的标准Python接口。
  • Pillow: Python图像库为您的Python解释器添加了图像处理功能。该库提供了广泛的文件格式支持、高效的内部表示和相当强大的图像处理能力。可以使用以下命令安装它:
pip install Pillow

循序渐进的方法:

  • 首先,我们必须导入模块。
Python3
# import required modules
import tkinter as tk
from tkinter import *
from PIL import Image
from PIL import ImageTk


Python3
# adjust window
root = tk.Tk()
root.geometry("200x200")
  
# loading the images
img = ImageTk.PhotoImage(Image.open("photo1.png"))
img2 = ImageTk.PhotoImage(Image.open("photo2.png"))
img3 = ImageTk.PhotoImage(Image.open("photo3.png"))
  
l = Label()
l.pack()


Python3
# using recursion to slide to next image
x = 1
  
# function to change to next image
def move():
    global x
    if x == 4:
        x = 1
    if x == 1:
        l.config(image=img)
    elif x == 2:
        l.config(image=img2)
    elif x == 3:
        l.config(image=img3)
    x = x+1
    root.after(2000, move)
  
# calling the function
move()


Python3
root.mainloop()


Python3
# import required modules
import tkinter as tk
from tkinter import *
from PIL import Image
from PIL import ImageTk
  
  
  
# adjust window
root=tk.Tk()
root.geometry("200x200")
  
# loading the images
img=ImageTk.PhotoImage(Image.open("photo1.png"))
img2=ImageTk.PhotoImage(Image.open("photo2.png"))
img3=ImageTk.PhotoImage(Image.open("photo3.png"))
  
l=Label()
l.pack()
  
  
  
# using recursion to slide to next image
x = 1
  
# function to change to next image
def move():
    global x
    if x == 4:
        x = 1
    if x == 1:
        l.config(image=img)
    elif x == 2:
        l.config(image=img2)
    elif x == 3:
        l.config(image=img3)
    x = x+1
    root.after(2000, move)
  
# calling the function
move()
  
  
  
root.mainloop()


  • 加载图像。

# adjust window
root = tk.Tk()
root.geometry("200x200")
  
# loading the images
img = ImageTk.PhotoImage(Image.open("photo1.png"))
img2 = ImageTk.PhotoImage(Image.open("photo2.png"))
img3 = ImageTk.PhotoImage(Image.open("photo3.png"))
  
l = Label()
l.pack()
  • 现在我们必须创建一个名为move的函数来使图像移动(这里的意思是一个图像出现,移动后它消失。

# using recursion to slide to next image
x = 1
  
# function to change to next image
def move():
    global x
    if x == 4:
        x = 1
    if x == 1:
        l.config(image=img)
    elif x == 2:
        l.config(image=img2)
    elif x == 3:
        l.config(image=img3)
    x = x+1
    root.after(2000, move)
  
# calling the function
move()
  • 现在我们只需要调用 tkinter 的 mainloop函数来结束任务。

root.mainloop()
  • 全码=

# import required modules
import tkinter as tk
from tkinter import *
from PIL import Image
from PIL import ImageTk
  
  
  
# adjust window
root=tk.Tk()
root.geometry("200x200")
  
# loading the images
img=ImageTk.PhotoImage(Image.open("photo1.png"))
img2=ImageTk.PhotoImage(Image.open("photo2.png"))
img3=ImageTk.PhotoImage(Image.open("photo3.png"))
  
l=Label()
l.pack()
  
  
  
# using recursion to slide to next image
x = 1
  
# function to change to next image
def move():
    global x
    if x == 4:
        x = 1
    if x == 1:
        l.config(image=img)
    elif x == 2:
        l.config(image=img2)
    elif x == 3:
        l.config(image=img3)
    x = x+1
    root.after(2000, move)
  
# calling the function
move()
  
  
  
root.mainloop()

输出:
