Python 如何将 PyCBitmap 保存为 jpg 格式的文件?

import os
from PIL import Image

for root, dirs, files in os.walk("."):
for bmpfig in files:
if not bmpfig.endswith('.bmp') and not bmpfig.endswith('.png'):
continue
bmpfig = os.path.join(root, bmpfig)
newfigname = bmpfig[:-4] + ".jpg"
print "converting from", bmpfig, "to", newfigname
img = Image.open(bmpfig)
img = img.convert('RGB') # for png
img.save(newfigname, format='jpeg', quality=95)
img.close()
os.remove(bmpfig)
