python勾画图片轮廓,实现程序代码如下：
#filename:
koutu.py
from PIL import Image
from PIL import ImageFilter
im = Image.open('C:\hcxy.jpg')
om = im.filter(ImageFilter.CONTOUR)
om.save('C:\hcxyeducn.jpg')
#filename:
from PIL import Image
from PIL import ImageFilter
im = Image.open('C:\hcxy.jpg')
om = im.filter(ImageFilter.CONTOUR)
om.save('C:\hcxyeducn.jpg')
