将一副图以灰度值转化成黑白字符画
代码如下:
# -*- coding:utf-8 -*-
from PIL import Image
IMG = r'F:\PythonFiles\PycharmFile\ex10CharacterGraph.jpg' #文件路径
WIDTH = 80 #定义输出画面的宽度
HEIGHT = 45 #定义
ascii_char = list("[email protected]%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,\"^`'. ") #所用字符列表
# 将256灰度映射到70个字符上
def get_char(r, g, b, alpha=256): # alpha透明度
if alpha == 0:
return ' '
length = len(ascii_char)
gray = int(0.2126 * r + 0.7152 * g + 0.0722 * b) # 计算灰度
unit = (256.0 + 1) / length
return ascii_char[int(gray / unit)] # 不同的灰度对应着不同的字符
# 通过灰度来区分色块
if __name__ == '__main__': #__name__ == '__main__'表示以下程序只要在本文件运行时才执行;若该文件被其他文件import引用,以下程序则不执行
im = Image.open(IMG)
im = im.resize((WIDTH, HEIGHT), Image.NEAREST)
txt = ""
for i in range(HEIGHT):
for j in range(WIDTH):
txt += get_char(*im.getpixel((j, i)))
txt += '\n'
print(txt) #输出图像
# 将图像写入txt文件
with open("ex10CharacterGraph_Graph.txt", 'w') as f:
f.write(txt)
效果图:
