[두근두근 파이썬 12장] 실습 11주차

컴퓨팅적 사고와 문제 해결 5월 26 실습과제(두근두근파이썬 12장 도전문제)

 

 

도전문제 1(흑백 사진으로 만들기)

from PIL import Image, ImageTk, ImageFilter, ImageDraw
import tkinter as tk
from tkinter import filedialog as fd

im = None
tk_img  = None

#파일 열기
def open():
    global im, tk_img
    fname = fd.askopenfilename()
    im = Image.open(fname)
    tk_img = ImageTk.PhotoImage(im)
    canvas.create_image(250,250,image=tk_img)
    window.update()

#프로그램 종료
def quit():
    window.quit()

#흑백화면으로 변환
def image_convert_bw():
    global im, tk_img
    out = im.convert('L')
    tk_img = ImageTk.PhotoImage(out)
    canvas.create_image(250,250,image=tk_img)
    window.update()

window = tk.Tk()
canvas = tk.Canvas(window, width = 500, height = 500)
canvas.pack()

menubar = tk.Menu(window)
filemenu = tk.Menu(window)
ipmenu = tk.Menu(window)
filemenu.add_command(label = "열기",command = open)
filemenu.add_command(label = "종료",command = quit)
ipmenu.add_command(label = "흑백화면으로 전환", command=image_convert_bw)
menubar.add_cascade(label = "파일", menu = filemenu)
menubar.add_cascade(label = "영상처리", menu = ipmenu)

window.config(menu = menubar)
window.mainloop()

 

 

 

 

 

 

도전문제 2(미니 포토샵 - 5가지 영상 처리 기능 만들기)

 

-엣지 강조 필터

-텍스트 상자 만들기

-사진 잘라내기

-특정한 색깔을 다른 색깔로 변환하기

-두 사진 합치기
