Question

我正在从系统中获取图像，并且在单击“加载图像”按钮时需要显示一个新标签。我需要在一个定义了大小的名为“ canvas”的标签中显示完整的图像，但是我只能得到图像的一部分。

我的代码工作得很好，只显示了一部分图像。

from tkinter import *
from tkinter import filedialog
from PIL import ImageTk ,Image
import os

root = Tk()
root.title("Images")

def Clicked():
    filename = filedialog.askopenfilename(initialdir=os.getcwd(), title="Select file", filetypes=(("png images", ".png, .jpg"), ("all files", "*.*")))
    if not filename:
        return
    image = ImageTk.PhotoImage(Image.open(filename))   #need to resize this image
    loaded = Label(frame, text = "\n\n\nLoaded Image\n", font = ('Arial',10,'bold')).grid(row = 5)
    canvas = Label(frame, width = 150, height =150, relief = "groove", borderwidth = 2, image = image)
    canvas.image = image
    canvas.grid(row = 6)


frame = Frame(root, relief = "solid", borderwidth = 1)
frame.pack()



label = Label(frame, text = "Content Based Image Retrieval\n", font = ('Arial', 15), padx = 10, pady =10).grid(row = 0)


content = Label(frame, text = "Contents\n\n",font=('Arial',10), padx = 20).grid(row = 1 , column = 0, sticky = W)

loadImg = Button(frame, text = "Load Image", relief = "groove", padx = 10, pady = 5, command = Clicked).grid( row = 2)

blank = Label(frame, text ="").grid(row = 3)

searchImg = Button(frame, text = "Search Image", relief = "groove", padx = 6, pady = 5).grid( row = 4)

blank = Label(frame, text ="").grid(row = 7)

root.mainloop()

Answer 1

唯一的解决方案是在显示图像之前使用其他一些库（例如Pillow）调整图像大小。 tkinter唯一需要调整图像大小的功能是将其缩放为2倍。

在Tkinter中以定义的尺寸标签显示整个图像
