Then, I'd like to define the FOV on the *shorter* axis for the Lensfun project. Lensfun needs a clearer definition than Hugin because it doesn't have the image size but only crop factor and aspect ratio >= 1. By using the shorter axis, we can re-use the scaling parameters calculated for the distortion coordinate system, and needn't introduce yet another coordinate system. However, Hugin must then re-calculate the FOV value returned by the Lensfun database for the particular projection and image orientation. For the general case, it must do so anyway because users may feed images in any orientation into Hugin. I'm about to implement this in Lensfun today, but it is not much code, and I can wait with it if someone on this list wants to talk about it.
