MJ裁剪4张图片

有幽默宽高，可以调整
还有比例，需要自己调整

  1. from PIL import Image
  2. import os
  3. import os.path
  4. # long=int(input('图片长度像素（2048,2912）\n'))
  5. # wide=int(input('图片宽度像素（2048,1632）\n'))
  6. # 2688 1792
  7. long = input("默认2688")
  8. if long :
  9.     pass
  10. else:
  11.     long = 2688
  12. wide = input("默认1792")
  13. if wide :
  14.     pass
  15. else:
  16.     wide = 1792
  17. # 1:1图比例是2048
  18. # 16:9图片比例 2912:1632
  20. # 定义文件所在文件夹
  21. image_dir = '/xxx/xxx/图片放这里双击cut'
  22. # 本文件文件名
  23. this_name = "cut.py"
  24. for parent, dir_name, file_names in os.walk(image_dir):  # 遍历每一张图片
  25.     file_names.remove(this_name)
  26.     try:
  27.         file_names.remove(".DS_Store")
  28.     except:
  29.         pass
  30.     for filename in file_names:
  31.         print(filename)
  32.         pic_name = os.path.join(parent, filename)
  33.         image = Image.open(pic_name)
  34.         _width, _height = image.size
  35.         print(_width, _height)
  38.         # 四张图片的坐标
  39.         t1=[0,0,float(long/2),float(wide/2)]
  40.         t2=[float(long/2),0,long,float(wide/2)]
  41.         t3=[0,float(wide/2),float(long/2),wide]
  42.         t4=[float(long/2),float(wide/2),long,wide]
  44.         pic=t1+t2+t3+t4
  45.         print(pic)
  46.         # [0, 0, 1456.0, 816.0, 1456.0, 0, 2912, 816.0, 0, 816.0, 1456.0, 1632, 1456.0, 816.0, 2912, 1632]
  48.         for p in range(int(len(pic)/4)):
  49.             pp=pic[p*4:p*4+4]
  50.             print(pp)
  52.             # 定义裁剪范围(left, upper, right, lower)
  53.             # # box = image.crop((0,0,123,123))
  54.             box = image.crop((pp[0],pp[1],pp[2],pp[3]))
  55.             box = box.resize((long/2, wide/2))
  56.             name = filename[:-4]+'_'+str(p) +'.png'
  58.             box.save('/xxx/xxx/xxx/图片放这里双击cut/%s' % name)
  59.     print('Done!')
