Set affine to also accept Polynomial 1 fits.
Explicit CRS to retain beside the world file.
Six newline-separated values in A, D, B, E, C, F order, including the pixel-centre offset.
"@georeferencing/core".GeoreferenceError For ineligible models or different working/output CRSs.
Create a six-line world file plus an explicit CRS sidecar value for Linear or Helmert fits (and optionally affine fits) without reprojection.
Line order is A, D, B, E, C, F. The final two values locate the first pixel centre,
[0.5, 0.5]. A world file alone contains no CRS.
