lsst::afw::image::MaskedImage< ImagePixelT, MaskPixelT, VariancePixelT >::MaskedImage ( lsst::geom::Box2I const &  bbox, MaskPlaneDict const &  planeDict = MaskPlaneDict()  )

explicit

Create an MaskedImage of the specified size.

The Image, Mask, and Variance will be set to zero

Parameters

bbox	dimensions of image: width x height
planeDict	Make Mask conform to this mask layout (ignore if empty)

Note

Many lsst::afw::image and lsst::afw::math objects define a dimensions member which may be conveniently used to make objects of an appropriate size

Set the MaskedImage's origin.

Note

There are use cases (e.g. memory overlays) that may want to set these values, but don't do so unless you are an Expert.

MaskedImage lsst::afw::image::MaskedImage< ImagePixelT, MaskPixelT, VariancePixelT >::subset ( lsst::geom::Box2I const &  bbox, ImageOrigin  origin = PARENT  ) const

inline

Return a subimage corresponding to the given box.

Parameters

bbox	Bounding box of the subimage returned.
origin	Origin bbox is rleative to; PARENT accounts for xy0, LOCAL does not.

Returns

A subimage view into this.

This method is wrapped as getitem in Python.

Note

This method permits mutable views to be obtained from const references to images (just as the copy constructor does). This is an intrinsic flaw in Image's design.
