Python脚本批量修改照片大小

旅游归来，照片太多了。不想把原大小的照片和人分享，又懒的安装什么图像处理软件，于是用python写个脚本批量处理一下，一蹴而就：

   1:  import Image, os

   2:   

   3:  def resize(fname):

   4:      img = Image.open(fname)

   5:         

   6:      ratio = float(img.size[0]) / img.size[1]

   7:      width = int(ratio > 1 and 1024 or 1024 * ratio)

   8:      height = int(ratio > 1 and 1024 / ratio or 1024)

   9:      

  10:      resized_img = img.resize((width, height), Image.ANTIALIAS)

  11:      basename, extension = os.path.splitext(fname)

  12:      resized_img.save(basename+'_resized.jpg')

  13:   

  14:  if __name__ == '__main__':

  15:      path = os.path.abspath(os.curdir)

  16:      dirList = os.listdir(path);

  17:      for fname in dirList:

  18:          basename, extension = os.path.splitext(fname)

  19:          if extension.lower() == '.jpg':

  20:              resize(fname)
