Detailed Description

Multiband Pixel class

This represent acts as a container for a single pixel
(scalar) in multiple bands.

Parameters
----------
singles : `sequence`
   Either a list of single band objects or an array of values.
bands : `list`
   List of band names. If `singles` is an `OrderedDict` or
   a `MultibandPixel` then this argument is ignored,
   otherwise it is required.
position : `Point2I`
   Location of the pixel in the parent image.
   Unlike other objects that inherit from `MultibandBase`,
   `MultibandPixel` objects don't have a full `Box2I`
   bounding box, since they only contain a single pixel,
   so the bounding box cannot be inherited from the
   list of `singles`.

Constructor & Destructor Documentation

◆ init()

lsst.afw.image._image._multiband.MultibandPixel.__init__	(	self,
		bands,
		singles,
		position )

Definition at line 55 of file _multiband.py.

Member Function Documentation

◆ getitem()

lsst.afw.image._image._multiband.MultibandPixel.__getitem__	(		self,
			indices )

Get a slice of the underlying array

Since a `MultibandPixel` is a scalar in the
spatial dimensions, it can only be indexed with
a band name, number, or slice.

Definition at line 100 of file _multiband.py.

◆ iter()

lsst.afw.multiband.MultibandBase.__iter__ ( self )

inherited

Definition at line 172 of file multiband.py.

◆ len()

lsst.afw.multiband.MultibandBase.__len__ ( self )

inherited

Definition at line 144 of file multiband.py.

◆ next()

lsst.afw.multiband.MultibandBase.__next__ ( self )

inherited

Definition at line 176 of file multiband.py.

◆ repr()

lsst.afw.multiband.MultibandBase.__repr__ ( self )

inherited

Definition at line 310 of file multiband.py.

◆ str()

lsst.afw.multiband.MultibandBase.__str__ ( self )

inherited

Definition at line 315 of file multiband.py.

◆ _bandNamesToIndex()

lsst.afw.multiband.MultibandBase._bandNamesToIndex	(		self,
			bandIndex )

protectedinherited

Convert a list of band names to an index or a slice

Parameters
----------
bandIndex: iterable or `object`
    Index to specify a band or list of bands,
    usually a string or enum.
    For example `bandIndex` can be
    `"R"` or `["R", "G", "B"]` or `[Band.R, Band.G, Band.B]`,
    if `Band` is an enum.

Returns
-------
bandNames: `list`
    Names of the bands in the slice
bandIndex: `slice` or `list` of `int`
    Index of each band in `bandNames` in
    `self.bands`.

Definition at line 184 of file multiband.py.

◆ _getArray()

lsst.afw.image._image._multiband.MultibandPixel._getArray ( self )

protected

Data cube array in multiple bands

Since `self._singles` is just a 1D array,
`array` just returns `self._singles`.

Definition at line 70 of file _multiband.py.

◆ _setArray()

lsst.afw.image._image._multiband.MultibandPixel._setArray	(		self,
			value )

protected

Definition at line 78 of file _multiband.py.

◆ _slice()

lsst.afw.image._image._multiband.MultibandPixel._slice	(	self,
		bands,
		bandIndex,
		indices )

protected

Slice the current object and return the result

Different inherited classes will handling slicing differently,
so this method must be overloaded in inherited classes.

Parameters
----------
bands: `list` of `str`
    List of band names for the slice. This is a subset of the
    bands in the parent multiband object
bandIndex: `list` of `int` or `slice`
    Index along the band dimension
indices: `tuple` of remaining indices
    `MultibandBase.__getitem__` separates the first (band)
    index from the remaining indices, so `indices` is a tuple
    of all of the indices that come after `band` in the
    `args` passed to `MultibandBase.__getitem__`.

Returns
-------
result: `object`
    Sliced version of the current object, which could be the
    same class or a different class depending on the
    slice being made.

Reimplemented from lsst.afw.multiband.MultibandBase.

Definition at line 124 of file _multiband.py.

◆ bands()

lsst.afw.multiband.MultibandBase.bands ( self )

inherited

List of band names for the single band objects

Definition at line 86 of file multiband.py.

◆ clone()

lsst.afw.image._image._multiband.MultibandPixel.clone	(		self,
			deep = True )

Make a copy of the current instance

`MultibandPixel.singles` is an array,
so this just makes a copy of the array
(as opposed to a view of the parent array).

Reimplemented from lsst.afw.multiband.MultibandBase.

Definition at line 84 of file _multiband.py.

◆ getBBox()

lsst.afw.multiband.MultibandBase.getBBox ( self )

inherited

Bounding box

◆ getXY0()

lsst.afw.multiband.MultibandBase.getXY0 ( self )

inherited

Minimum coordinate in the bounding box

◆ height()

lsst.afw.multiband.MultibandBase.height ( self )

inherited

Height of the images

Definition at line 139 of file multiband.py.

◆ origin()

lsst.afw.multiband.MultibandBase.origin ( self )

inherited

Minimum (y,x) position

This is the position of `self.getBBox().getMin()`,
but available as a tuple for numpy array indexing.

Definition at line 124 of file multiband.py.

◆ setXY0()

lsst.afw.multiband.MultibandBase.setXY0	(		self,
			xy0 )

xy0: `Point2I`
    New minimum bounds of the bounding box

Reimplemented in lsst.afw.image._image._multiband.MultibandTripleBase.

Definition at line 228 of file multiband.py.

◆ shiftedBy()

lsst.afw.multiband.MultibandBase.shiftedBy	(		self,
			offset )

inherited

Shift a bounding box by an offset, but keep the same Extent

This method is broken until DM-10781 is completed.

Parameters
----------
offset: `Extent2I`
    Amount to shift the bounding box in x and y.

Returns
-------
result: `MultibandBase`
    A copy of the object, shifted by `offset`

Definition at line 262 of file multiband.py.

◆ shiftedTo()

lsst.afw.multiband.MultibandBase.shiftedTo	(		self,
			xy0 )

inherited

Shift the bounding box but keep the same Extent

This method is broken until DM-10781 is completed.

Parameters
----------
xy0: `Point2I`
    New minimum bounds of the bounding box

Returns
-------
result: `MultibandBase`
    A copy of the object, shifted to `xy0`.
