Drop shadow using distans from edge. This method is fast because shadow area is filled by one pass and flexible because attenuation can be represented by a function of distance from edge.
import sys
import os
import math
import Image
def create_shadow_image(image_size, shadow_size):
mergin = (shadow_size, shadow_size)
new_size = map(sum, zip(image_size, mergin, mergin))
im = Image.new('RGBA', new_size, 0xFFFFFFFF)
buf = im.load()
