i blend 2 images, 1 smaller , enclosed larger one, assume both rectangular. blend these 2 there smooth transition in rectangular band around smaller image. trying in matlab. example here 2 images shown on top of each other, orange , black mages: i create transition band around orange image such @ outward boundaries of band alpha map orange image has value of 0 , inward boundaries have value of 1 , there smooth transition 0 1 inside gray band shown below: i looking map gray area 2-d matrix has values between 0 , 1. there equation based or ready made such matrix? know can create simple linear transition vertical or horizontal band example if x shows x-coordinate of left edge of inner image , blending width w can use this: alpha(x) = (x-x)/w x<x<x+w 1 x > x+w but how create such alpha in 2-d?

i have application made of several "levels" of elements. elements parent of 0..n children elements, being parent of 0..n other elements. top level type has no parent , bottom level elements have no children. in other words, let 3 types : a, b , c. instance of parent of multiple instances of b, being parents of multiple instances of c. each instance has (strongly typed) reference parent. i have several methods same in parent classes, addchild, removechild, getchildindex, etc. have base class parent classes in order not duplicate these methods each parent type. the idea that, when deriving parent base class, have provide type of children, depending on type of parent. so far have come overly complex design : public interface ichild<tparent> tparent : parentbase<ichild<tparent>> { tparent parent { get; set; } } public class parentbase<tchild> tchild : ichild<parentbase<tchild>> { public list<tchild> children; } pub...

i've been playing graphql while now, using both graphql-js (javascript) , graphene (python). graphql comes relay spec pagination, awesome our schema. find hard set mind on filters. every database provides full query language (whether sql or nosql). our simple web apps, need access our data, of interesting stuff happens in client side rich js frameworks. so after reviewing few of our backend apps, can see parsers: parsing requests rest mongodb or sql . we try provide rich queries client side, add arguments our graphql endpoints, every new filter requires lot of work (new code). going rest graphql great, why not take little farther more expressive language data querying? there reason restrictions? should keep develop "parsers"? to clarify point made above, graphql spec not include relay , mentions nothing pagination. in fact, graphql doesn't specify network layer either choice use http implementor. so graphql provide: a strong t...
