## Fisheye to panoramic

### Description

Fisheye to panoramic (cylindrical projection)

### Usage

```fisheye_to_pano(r, z, a, fun = mean, angle_width = 1)
```

### Arguments

 `r` SpatRaster. `z` SpatRaster built with `zenith_image`. `a` SpatRaster built with `azimuth_image`. `fun` A `function` that takes a vector as input and returns a one-length numeric or logical vector as output (e.g. mean). `angle_width` Numeric vector of length one. It should be ```30, 15, 10, 7.5, 6, 5, 3.75, 3, 2.5, 1.875, 1``` or `0.5` degrees. This constrain is rooted in the requirement of a value able to divide both the `0` to `360` and `0` to `90` ranges into a whole number of segments.

### Details

An early version of this function was used in \insertCiteDiaz2021;textualrcaiman.
