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](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)`
