在 tkinter 中，有没有办法绘制平滑的曲线？

Question

A line item can actually be a series of line segments, not just one; in our example, we could have chosen to use a single line item for each complete stroke. The line can also be drawn directly point-to-point, or smoothed out into a curved line.

These lines are from the tkinter docs - https://tkdocs.com/tutorial/canvas.html#types

But in this it says that a line(on the tkinter canvas) can be drawn directly point-to-point, or smoothed out into a curved line.

But I have not yet been able to find a way to do that, kindly help me with the same.

Edit:

My code is too big and messy for it to be completely shown but I hope these three functions below will help people.

Also it really just about a normal painting program(or atleast you can take it like one.)

def clear_prev_draw_coords(event = None) :
    global last_draw_x, last_draw_y, pen_color, pen_size

    last_draw_x, last_draw_y = None, None
    drawing_coord_list.clear()
    return

def draw() :
    last_img_x = 0
    last_img_y = 0
    canvas.create_line(last_draw_x, last_draw_y, x2, y2, fill = pen_color, width = pen_size, tag = tag, smooth = 1)

    last_draw_x, last_draw_y = x2, y2
    return

def toggle_pen_mode(dummy = None) :
    global mode

    mode = 'pen'

    root.bind("<B1-Motion>", draw)
    root.bind("<ButtonRelease-1>", clear_prev_draw_coords)
    return

Have you read effbot ? You can find a lot of information about all possible flags and options. This mini example creates a curved line with the smooth -flag:

from tkinter import *

master = Tk()

w = Canvas(master, width=200, height=100)
w.pack()

w.create_line(150,0, 100,50, 50,0, 0,50, smooth=1)

mainloop()
