使用convert 裁剪图片，支持批量处理

cut.py

import sh
import sys

cfgfile = sys.argv[-1]

for line in open(cfgfile):
    line = line.strip()
    split_line = line.split(',')
    print(split_line)

    in_file = split_line[0]
    out_file = split_line[1]
    arg = split_line[2]

    sh.convert('-resize', arg, in_file, out_file)
