将元组从函数导入列表

Question

我正在尝试在循环中使用范围修改像素，但我无法从大小函数导入范围。

    load = bnw.load()
    loadpx = [
        (a),
        (b)
    ]
    bnw.size(loadpx)
    print(loadpx)
    for x in a:
        for y in b:
            new = load[x,y] + 10
            if new > 254:
                new = 254

            bnw = new

bnw.size 的输出应该是图像的像素数。 (1920,1080)。在知道大小 a 被输入到 x 和 b 到 y 之后。

第一个答案的完整代码返回相同的错误

import tkinter as tk
import random
import os
import time
from tkinter import filedialog
from PIL import Image
import numpy as np  


main_window = tk.Tk()
main_window.title("foto epic")
judul = tk.Label(main_window, text="                Editor Instagram epic 2 BnW Edition wkwk                \n\n Silahkan Input foto Dibawah\n\/\n")
judul.pack()

def UploadAction():
    file = filedialog.askopenfilename()
    print('Selected:', file)
    img = Image.open(file)
    bnw2 = img.convert(mode = "L")
    print(bnw2.size)
    load = bnw2.load()
    r,c = bnw2.size()
    for x in range(r):
        for y in range(c):
            new = load[x,y] + 10
            if new > 254:
                new = 254

            new = bnw2
    arraying = np.asarray(bnw2)
    counting = np.bincount(arraying.flatten(), minlength = 128)
    px_num = np.sum(counting)

    counting = counting/px_num
    sum1 = np.cumsum(counting)
    floorcount = np.floor(255 * sum1).astype(np.uint8)
    donecount = list(arraying.flatten())

    transforming = [floorcount[p] for p in donecount]
    transforming = np.reshape(np.asarray(transforming), arraying.shape)
    done_transform = Image.fromarray(transforming)
    done = tk.Label(main_window, text=" \nFoto Telah di export!\nTerimakasih Sudah Menggunakan Program ini!\n")
    done.pack()
    done_transform.show()
    if os.path.exists('result.jpg'):
        done_transform.save('result_{}.jpg'.format(int(time.time())))
    else:
        done_transform.save('result.jpg')

button = tk.Button(main_window, text='Beautify!', command=UploadAction)
button.pack()

tk.mainloop()

我用的是Tkinter UI不知道会不会影响原题

错误

Selected: D:/Code/Kuliah/Semester 3/citra/yes/DSC_3044.jpg

    r,c = bnw2.size()
TypeError: 'tuple' object is not callable

Answer 1

我在这里编辑了现在应该可以使用的答案：

file = filedialog.askopenfilename()
print('Selected:', file)
img = Image.open(file)
bnw2 = img.convert(mode = "L")
load = bnw2.load()
r,c = bnw2.size
for x in range(r):
    for y in range(c):
        new = load[x,y] + 10
        if new > 254:
            new = 254

        load[x,y] = new
