Yes, the third dimension is of size 3.
The `grayim` returns:
julia> img = grayim(pauliRGBeq)
Gray Image with:
data: 825x1000x3 Array{Float64,3}
properties:
colorspace: Gray
spatialorder: x y z
But `view` returns:
julia> view(img)
ERROR: `view` has no method matching
view(::Image{Float64,3,Array{Float64,3}})
This probably is relevant: The data is originally in gray scale, but we use
a decomposition to artifictiallty color it (Pauli Decomposition). The
function used to do it uses `reshape` to return the 3 Arrays together as
the same variable for the image:
pauliRGBeq = reshape([[A_Band],[B_Band],[C_Band]],(width,height,3))
And pauliRGBeq is the variable we want to view in a new window or plot in
order to select regions (that's the reason we need to either use mouse
events or mark it with a coordinate system to select)
Also, note that we are able to write it to a file using
imwrite(pauliRGBeq, "/home/folder/testimage.png")
Best,
