lentil.Plane.rescale#

Plane.rescale(scale)[source]#

Rescale a plane via interpolation.

The following Plane attributes are resampled:

Plane.amplitude is rescaled via 3rd order spline interpolation. The
result is scaled to preserve total power.
Plane.opd is rescaled via 3rd order spline interpolation.
Plane.mask is rescaled via 0-order nearest neighbor interpolation.
Plane.pixelscale is adjusted appropriately.

Parameters:: scale (float) – Scale factor for interpolation. Scale factors less than 1 shrink the Plane while scale factors greater than 1 grow it.
Returns:: plane
Return type:: Plane

Notes

All interpolation is performed via scipy.ndimage.map_coordinates
