24.39 CCfits::PHDU Class Reference 129
dummy header. PHDU instances are only created by FITS ctors. In the first release of
CCfits, the Primary cannot be changed once declared.
PHDU and ExtHDU provide the same interface to writing images: multiple overloads
of the templated PHDU::read and PHDU::write operations provide for (a) writing image
data specified in a number of ways [C-array, std::vector, std::valarray] and with input
location specified by initial pixel, by n-tuple, and by rectangular subset [generalized
slice]; (b) reading image data specified similarly to the write options into a std::valarray.
Todo Implement functions that allow replacement of the primary image
24.39.2 Constructor & Destructor Documentation
24.39.2.1 CCfits::PHDU::∼PHDU ( ) [virtual]
destructor
Destructor
24.39.2.2 CCfits::PHDU::PHDU ( const PHDU & right ) [protected]
copy constructor
required for cloning primary HDUs when copying FITS files.
24.39.2.3 CCfits::PHDU::PHDU ( FITSBase ∗ p, int bpix, int naxis, const std::vector< long > &
axes ) [protected]
Writing Primary HDU constructor, called by PrimaryHDU class.
Constructor used for creating new PHDU (i.e. for writing data to FITS). also doubles
as default constructor since all arguments have default values, which are passed to the
HDU constructor
24.39.2.4 CCfits::PHDU::PHDU ( FITSBase ∗ p = 0 ) [protected]
Reading Primary HDU constructor.
Constructor used when reading the primary HDU from an existing file. Does nothing
except initialize, with the real work done by the subclass PrimaryHDU.
24.39.3 Member Function Documentation
24.39.3.1 void CCfits::PHDU::initRead ( ) [protected, virtual]
Read image header and update fits pointer accordingly.
Private: called by ctor.
