[Octave-bug-tracker] [bug #44799] image package: imrotate chrashes when using 'spline' as interpolation method

[Carnë Draug]

Follow-up Comment #7, bug #44799 (project octave):

I would like to avoid saying that the spline method does not work on the
documentation, because once it does work in core, it automatically works in
the image package.  I made mention of the core version then:

http://hg.code.sf.net/p/octave/image/rev/7f31f3eef4c9

As a fix, I tried to replace interp2 with interpn whose implementation of
spline seems to work fine for out of order grids.  However, seems like interpn
behaves slightly different and different methods had different issues.  They
were not wrong, theyr were rotate around a corner instead a center, or rotated
in the other direction, or things like that. Not sure if an issues with
interpn or the preparation of data to interpn.
