Follow up question from Replacing a quadrilateral with a square generated from PIL.QUAD
I am able to overlay the image perfectly, but want ways to blur just the edges. I took a look at composite_channel and the list of operators (http://docs.wand-py.org/en/0.4.1/wand/image.html#wand.image.COMPOSITE_OPERATORS) and while luminize seems to work well as an operator, it still does not blur the edges. Are there ways to do this with wand?
