Could Warp function be used to do a projective transformation of an image using a 3x3 matrix? about imagetransformations.jl HOT 2 CLOSED

I don't know the function you speak of. The gist of warp is that it uses https://github.com/FugroRoames/CoordinateTransformations.jl to represent transformations. so if you can represent it using what that package provides it should more or less work.

I am pretty sure we would need some custom tweaking somewhere though as I believe LinearMap and AffineMap both make the assumption that the first two elements of the 3x3 transformation matrix are zero and thus just omits them entirely.

This seems to be a very similar question to #64 so I'll close it.

The short answer is yes, as long as you wrap it with a function that inputs a SVector and outputs a SVector. https://github.com/JuliaGeometry/CoordinateTransformations.jl is a convenient package that could possibly create such a function (although I didn't put my hands on it).
