I'm trying to modify pixels using range in a loop but I can't import the range from size function.

    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

The output from bnw.size should be the number of pixels the image has ex. (1920,1080). after knowing the size a is inputted to the x and b to y.

the full code withe the first answer returned the same error

    done_transform.show()

    else:
        done_transform.save('result.jpg')

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

tk.mainloop()

I use Tkinter for UI I don't know if it would affect the original question

the error

CodePudding user response：

Here i edited the answer this should work now:

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
