CellIJ

class lsst.images.cells.CellIJ(i: int, j: int)

Bases: object

An index in a grid of cells.

Notes

This is deliberately not a tuple or other Sequence in order to make it typing-incompatible with sequence-based pixel coordinate pairs (e.g. YX). This also allows it to have addition and subtraction operators.

Methods Summary

as_tuple()	Convert to an (i, j) tuple.
from_legacy(legacy_index)	Convert from a legacy lsst.skymap.Index2D instance.
to_legacy()	Convert to a legacy lsst.skymap.Index2D instance.

Methods Documentation

as_tuple() → tuple[int, int]

Convert to an (i, j) tuple.

static from_legacy(legacy_index: LegacyIndex2D) → CellIJ

Convert from a legacy lsst.skymap.Index2D instance.

Notes

lsst.skymap.Index2D is ordered (x, y), i.e. (j, i).

to_legacy() → LegacyIndex2D

Convert to a legacy lsst.skymap.Index2D instance.

Notes

lsst.skymap.Index2D is ordered (x, y), i.e. (j, i).
