BoundaryConditions::constant_exterior(source, 1.0f), how to expand the image by top-bottom-left-right directions. but i debug it and find its difference, it is right?

[halcomcn]

limit = BoundaryConditions::constant_exterior(source, 1.0f);

according to that picture, i hope it will get [1] result, but i use the code"limit = BoundaryConditions::constant_exterior(source, 1.0f)", it print [2] result.

thanks for your reply.

if a RDom r.x range (-1 , 3), when limit(x +r.x) is running,( limit = BoundaryConditions::constant_exterior(source, 1.0f); ), you can see the index: x+r.x = -1(x=0), we will get a limit(-1) value? if we can get limit(-1) value, and then limit(-1) will be 1.0f?
