WebAttached is a patch (V1) that just allows complex input values in psf2otf, as desribed in comment #4.I have not seen any negative side effects. In the inverse function (otf2psf) complex input values are already possible, so I also added a new test to psf2otf that tests a roundtrip with those two functions using complex input values.
