## 目标 ##

将一张图片进行`虚化`，只显示出其`轮廓`，一个很酷的效果，但代码却只需要`四行`。

## 代码 ##

代码就只有这么短短的四行。

from PIL import Image,ImageFilter
      
    img = Image.open('/Users/fltenwall/Documents/轩灵/持剑小姐姐.jpg')
    newImg = img.filter(ImageFilter.CONTOUR)
    newImg.save('小姐姐.png','png')

## 下载依赖 ##

### 踩坑 ###

根据代码很容易联想是下载`PIL`，但结果：

### 解决 ###

正确的方法是下载依赖`Pillow`

#### 完美！ ####

## 封装为函数 ##

from PIL import Image,ImageFilter
      
    def ImageOutline(path,newName,formate):
    	img = Image.open(path)
    	newImg = img.filter(ImageFilter.CONTOUR)
    	imgName = newName + formate
    	newImg.save(imgName,formate)
