I’m trying to write a simple function that replaces the corners of an array with a value. This is what I have so far: function replaceCorners!(a::AbstractArray{String, 2}, v::String) a[1, 1] = a[1, size(a)[2]] = a[size(a)[1], 1] = a[size(a)...] = v end I have a few questions about this problem…

Here’s a simple solution for doing this in general. firstlast(x) = first(x):length(x)-1:last(x) function replace_corners!(a::AbstractArray, v) a[firstlast.(axes(a))...] .= (v,) return a end

FWIW, ImageTransformations has CornerIterator
