Functions

template<typename T>
std::shared_ptr<PixelArrayBase> makePixelArray(int bitpix, ndarray::Array<T, 1, 1> const &array)

Create a PixelArray suitable for an image with the nominated BITPIX

Return

A new PixelArray.

Parameters

  • [in] bitpix: Bits per pixel (0,8,16,32,64,-32,-64) for output.

  • [in] array: Array with pixel values to convert.

template<typename T>
struct Bitpix
#include <fitsCompression.h>

FITS BITPIX header value by C++ type.

template<typename T>
class PixelArray : public lsst::afw::fits::detail::PixelArrayBase
#include <fitsCompression.h>

Typed array of pixel values.

class PixelArrayBase
#include <fitsCompression.h>

Abstract base class for an array of pixel values

For writing pixels out with the C-based cfitsio API, it’s helpful to have a type-agnostic holder of the pixel values (because although we can template on the array type, the output type can be configured at run-time, which means we can’t use ndarray::Array as the carrier). This is essentially a C++-ish void* array.
