how to save images with the save button on the tkinter in python
To save image you have to use PIL.Image so don't assign PhotoImage to variable which you use to keep PIL.Image
edge = Image.fromarray(img)tk_edge = ImageTk.PhotoImage(edge)and you have to use filename to save it
edge.save(filename)Full working example
import tkinter as tkfrom tkinter import ttkfrom tkinter import filedialogfrom PIL import ImageTk, Image, ImageDrawimport cv2import numpy as np# --- functions ---def savefile(): filename = filedialog.asksaveasfile(mode='w', defaultextension=".jpg") if not filename: return edge.save(filename)# --- main ---root = tk.Tk()img = cv2.imread('face_person1.jpg')edge = Image.fromarray(img)tk_edge = ImageTk.PhotoImage(edge)label = tk.Label(root, image=tk_edge)label.pack()button = tk.Button(root, text="save as", command=savefile)button.pack()root.mainloop()
