"imgtrans" function under ImageProjectiveGeometry.jl not defined or identified

I am trying to utilise the function mentioned as imgtrans but getting :

julia> using ImageProjectiveGeometry
julia> newimg = imgtrans(I, p)
ERROR: UndefVarError: imgtrans not defined

I am prefering https://github.com/peterkovesi/ImageProjectiveGeometry.jl/blob/master/doc/projective.md#imgtrans

Thankyou.

Bit of a guess, but it may just need the module name
julia> newimg = ImageProjectiveGeometry.imgtrans(I, p)
