two additional notes:
I get the missing map information when trying to imwrite png
julia> imwrite(img,"a22.png")
ERROR: MethodError: `mapinfo` has no method matching mapinfo(::Type{Images.
ImageMagick}, ::Images.ImageCmap{Color.RGB{T<:Union{AbstractFloat,
FixedPointNumbers.FixedPoint}},2,Array{UInt8,2}})
Closest candidates are:
mapinfo(::Type{Color.RGB{FixedPointNumbers.UfixedBase{UInt8,8}}}, ::Any)
mapinfo(::Type{Color.AlphaColorValue{Color.RGB{FixedPointNumbers.
UfixedBase{UInt8,8}},FixedPointNumbers.UfixedBase{UInt8,8}}}, ::Any)
mapinfo{CT<:Union{Color.AbstractAlphaColorValue{C<:Color.ColorValue{T},T<:
Real},Color.ColorValue{T}}}(::Type{Color.RGB24}, ::AbstractArray{CT<:Union{
Color.AbstractAlphaColorValue{C<:Color.ColorValue{T},T<:Real},Color.
ColorValue{T}},N})

and with ImageView
julia> view(img)
