namespace lsst

Class for a simple mapping implementing a generic AstrometryTransform.

Remove all non-astronomical counts from the Chunk Exposure’s pixels.

Forward declarations for lsst::utils::Cache

For details on the Cache class, see the Cache.h file.

It uses a template rather than a pointer so that the derived classes can use the specifics of the transform. The class simplePolyMapping overloads a few routines.

A base class for image defects

Numeric constants used by the Integrate.h integrator routines.

Compute Image Statistics

Note

Gauss-Kronrod-Patterson quadrature coefficients for use in quadpack routine qng. These coefficients were calculated with 101 decimal digit arithmetic by L. W. Fullerton, Bell Labs, Nov 1981.

Note

The Statistics class itself can only handle lsst::afw::image::MaskedImage() types. The philosophy has been to handle other types by making them look like lsst::afw::image::MaskedImage() and reusing that code. Users should have no need to instantiate a Statistics object directly, but should use the overloaded makeStatistics() factory functions.

Functions

template<typename PixelT>
std::shared_ptr<Image<PixelT>> operator+(Image<PixelT> const &img, ImageSlice<PixelT> const &slc)

Overload operator+()

We require two of these, one for image+slice (this one) and one for slice+image (next one down)

Parameters

template<typename PixelT>
std::shared_ptr<Image<PixelT>> operator+(ImageSlice<PixelT> const &slc, Image<PixelT> const &img)

Overload operator+()

We require two of these, one for image+slice (previous one) and one for slice+image (this)

Parameters

template<typename PixelT>
void operator+=(Image<PixelT> &img, ImageSlice<PixelT> const &slc)

Overload operator+=()

We’ll only allow ‘image += slice’. It doesn’t make sense to add an image to a slice.

Parameters

template<typename PixelT>
std::shared_ptr<Image<PixelT>> operator-(Image<PixelT> const &img, ImageSlice<PixelT> const &slc)

Overload operator-()

We’ll only allow ‘image - slice’, as ‘slice - image’ doesn’t make sense.

Parameters

template<typename PixelT>
void operator-=(Image<PixelT> &img, ImageSlice<PixelT> const &slc)

Overload operator-=()

Only ‘image -= slice’ is defined. ‘slice -= image’ wouldn’t make sense.

Parameters

template<typename PixelT>
std::shared_ptr<Image<PixelT>> operator*(Image<PixelT> const &img, ImageSlice<PixelT> const &slc)

Overload operator*()

We’ll define both ‘image*slice’ (this one) and ‘slice*image’ (next one down).

Parameters

template<typename PixelT>
std::shared_ptr<Image<PixelT>> operator*(ImageSlice<PixelT> const &slc, Image<PixelT> const &img)

Overload operator*()

We’ll define both ‘image*slice’ (this one) and ‘slice*image’ (next one down).

Parameters

template<typename PixelT>
void operator*=(Image<PixelT> &img, ImageSlice<PixelT> const &slc)

Overload operator*=()

Only ‘image *= slice’ is defined, as ‘slice *= image’ doesn’t make sense.

Parameters

template<typename PixelT>
std::shared_ptr<Image<PixelT>> operator/(Image<PixelT> const &img, ImageSlice<PixelT> const &slc)

Overload operator/()

Only ‘image / slice’ is defined, as ‘slice / image’ doesn’t make sense.

Parameters

template<typename PixelT>
void operator/=(Image<PixelT> &img, ImageSlice<PixelT> const &slc)

Overload operator/=()

Only ‘image /= slice’ is defined, as ‘slice /= image’ doesn’t make sense.

Parameters

template<typename PixelT>
class ImageSlice : public lsst::afw::image::Image<PixelT>
#include <ImageSlice.h>

A class to specify a slice of an image

Public Types

Values:
