I tried using `convert` elementwise over a `reinterpret`ed array:
A = ones(Float64, 3, 1000, 1000);
B = reinterpret(HSV{Float64}, A);
C = [convert(RGB, B[i,j]) for i in 1:1000, j in 1:1000];
imwrite(C, "image.PNG")
However, this doesn't work, because the array comprehension doesn't appear
to be aware that the resulting array is of type Array{RGB{Float64}, 2}, and
instead gives Array{Any, 2} (although all elements are of type
RGB{Float64}), which then gives an error at the `imwrite` step because of a
type mismatch. It is also fairly slow. I also tried the following:
D = convert(RGB, B)
but this is invalid syntax.
Is there a straightforward way to do the conversion?
