Be careful with your type conversions: Unary minus on an unsigned integer: const float angle = -i;
Integer division: -detPitchU * detSizeU / 2 Are you sure the results of these calculations are correct? __________________________________ Andreas Gravgaard Andersen 8000, Aarhus C Mail: andreasg...@gmail.com Cell: +45 3165 8140 https://calendly.com/agravgaard On Mon, 16 May 2022 at 17:04, Fernando Hueso González <fernando.hu...@uv.es> wrote: > Hi Simon, thanks for the swift reply. > > > No, there is no way to transpose your projections.
