Plane type#

`ptype.ptype`(ptype)	Create a plane type object
`ptype.PType`(ptype)	An object to hold the type of a `Plane` or `Wavefront`

`field.Field`(data[, pixelscale, offset, tilt])	Two-dimensional discretely sampled complex field.
`field.boundary`(fields)	Compute the bounding extents around a number of Field objects.
`field.insert`(field, out[, intensity, weight])	Insert a field into an array.
`field.merge`(a, b[, enforce_overlap])	Merge two Fields
`field.overlap`(fields)	True if two Fields overlap, otherwise False
`field.reduce`(fields)	Reduce a number of Fields into a potentially smaller disjoint set where overlapping Fields are merged.

`extent.array_extent`(shape, shift[, parent_shape])	Compute the extent of a shifted array.
`extent.array_center`(extent)	Compute the center of an extent
`extent.intersect`(a, b)	Return True if two extents intersect, otherwise False
`extent.intersection_extent`(a, b)	Compute the extent of two overlapping extents
`extent.intersection_shape`(a, b)	Compute the shape of two overlapping extents.
`extent.intersection_slices`(a, b)	Compute slices of overlapping areas between two overlapping extents
`extent.intersection_shift`(a, b)	Compute the shift between two overlapping extents

Utility class for holding common lofic shared by classes that need to implement the tilt interface.

fourier.dft2(f, alpha[, shape, shift, ...])

Compute the 2-dimensional discrete Fourier Transform.

`helper.mesh`(shape[, shift, angle])	Generate a standard mesh.
`helper.boundary_slice`(x[, threshold, pad])	Find bounding row and column indices of data within an array and return the results as slice objects.
`helper.slice_offset`(slice, shape)	Compute the offset of the center of a 2D slice relative to the center of a larger array.
`helper.gaussian2d`(size, sigma)	2D Gaussian kernel.
