Python图片转字符
前段时间学习pillow写的,可以通过改变font_map改变转换的深度和字符。思路是先转换黑白大小,读取黑白值取范围读font_map转变。
from PIL import Image,ImageDraw,ImageFont import os import time def save(img,file_name) : if os.path.isfile(file_name+'.jpg') : save(img,file_name+'-') else : img.save(file_name+'.jpg','JPEG') font_map = [' ','.','i','I','J','C','D','O','S','Q','G','F','E','#','&','@'] img_name = 'bb' f_size = 16 f_num_x = 100 def main() : im = Image.open(img_name+'.jpg').convert('L') im = im.resize((f_num_x,int(f_num_x*im.size[1]/im.size[0]))) level = im.getextrema()[-1]/(len(font_map)-1) im = im.point(lambda i : int(i/level)) imn = Image.new('L',(im.size[0]*f_size,im.size[1]*f_size)) f = ImageFont.truetype('arial.ttf',f_size) d = ImageDraw.Draw(imn) for y in range(0,im.size[1]) : for x in range(0,im.size[0]) : pp = im.getpixel((x,y)) d.text((x*f_size,y*f_size),font_map[len(font_map)-pp-1],fill=255,font=f) save(imn,img_name) if __name__ == '__main__' : tt = time.time() main() print(time.time()-tt)
上实际效果:
