本文實例為大家分享了python制作縮略圖的具體代碼,供大家參考,具體內容如下
import cv2 #導入opencv模塊 from tkinter import * #導入tkinter模塊 from tkinter import ttk #tkinter最新的主題部件 from PIL import Image #初始化模塊 root = Tk() root.title('Pt') root.geometry('600x300') #查找圖片路徑,成功則顯示圖片 def searchPicture(): location = locOfPicture.get() img = cv2.imread(location) cv2.imshow("Image",img) #生成縮略圖 def setPicture(): # 獲取圖片路徑 location = locOfPicture.get() # 對圖片進行操作 im = Image.open(location) im.thumbnail((int(heightOfPicture.get()),int(widthOfPicture.get()))) im.save(nameOfImg.get(),'JPEG') label1 = ttk.Label(root,text='選擇圖片') label2 = ttk.Label(root,text='長:') label3 = ttk.Label(root,text='寬:') label4 = ttk.Label(root,text='文件名') #存儲輸入框中輸入的變量 locOfPicture = StringVar() heightOfPicture= StringVar() widthOfPicture = StringVar() nameOfImg = StringVar() entry1 = ttk.Entry(root,textvariable = locOfPicture,width=50) entry2 = ttk.Entry(root,textvariable=heightOfPicture,width=10) entry3 = ttk.Entry(root,textvariable=widthOfPicture,width=10) entry4 = ttk.Entry(root,textvariable=nameOfImg,width=25) button1 = ttk.Button(root,text='確定',command=searchPicture) button2 = ttk.Button(root,text='確定生成',command=setPicture) #進行界面布局 label1.grid(column=0,row=0) entry1.grid(column=1,row=0,columnspan=3) button1.grid(column=4,row=0) label2.grid(column=0,row=1) entry2.grid(column=1,row=1) label3.grid(column=2,row=1) entry3.grid(column=3,row=1) entry4.grid(column=1,row=2,columnspan=2) button2.grid(column=3,row=2) root.mainloop()

小編再分享一段代碼:
