from PIL import Image,ImageFilter,ImageOps

img = Image.open( 'D:\\01.jpg')

def dodge(a, b, alpha):

return min(int(a*255/ (256- -b*alpha)), 255)

def draw(img, blur=25, alpha=1.0):

img1 = img. convert('L')#图片转换成灰色

img2 = img1.copy()

img2 = ImageOps.invert(img2)

for i in range(blur): #模糊度

img2 = img2.filter(ImageFilter.BLUR)

width, height = img1.size

for x in range (width):

for y in range(height):

a = img1.getpixel((x,y))

b = img2.getpixel((x,y))

img1.putpixel((x,y), dodge(a, b, alpha))

img1.show()

img1.save( 'D:\\02.jpg')

draw(img)

代码就这么几行~

PS：这里的模糊度不高，所以手绘效果不好，可以根据自己需要调整哦~
