Detailed Description

Class providing native access to FITS images.

Intended use:

Public interface

Review Status

Test programs:
tFITSImage

Prerequisite

Etymology

This class provides native access to FITS images. 64bit, 32bit floating point, 32 bit and 16bit integer FITS images are presently supported.

Synopsis

A FITSImage provides native access to FITS images by accessing them with the TiledFileAccess class. The FITSImage is read only. We could implement a writable FITSImage but putting the mask would lose data values (uses magic blanking) and FITS is really meant as an interchange medium, not an internal format.

Because FITS uses magic value blanking, the mask is generated on the fly as needed.

Example

FITSImage im("in.fits");
LogIO logger(or);
ImageStatistics<Float> stats(im, logger);
Bool ok = stats.display(); // Display statistics

Motivation

This provides native access to FITS images.

Reimplemented from casacore::MaskedLattice< T >.

virtual Bool casacore::FITSImage::doGetSlice ( Array< Float > &  buffer,

virtual

Set the cache size as to "fit" the indicated path.

Reimplemented from casacore::LatticeBase.

virtual void casacore::FITSImage::setCacheSizeInTiles ( uInt  howManyTiles)
virtual

Set the actual cache size for this Array to be be big enough for the indicated number of tiles.

This cache is not shared with PagedArrays in other rows and is always clipped to be less than the maximum value set using the setMaximumCacheSize member function. tiles. Tiles are cached using a first in first out algorithm.

Reimplemented from casacore::LatticeBase.

void casacore::FITSImage::setMaskZero ( Bool  filterZero)
protected

Set the masking of values 0.0.

virtual void casacore::FITSImage::setMaximumCacheSize ( uInt  howManyPixels)
virtual

Set the maximum (allowed) cache size as indicated.

Reimplemented from casacore::LatticeBase.

void casacore::FITSImage::setup ( )
private

Setup the object (used by constructors).

virtual IPosition casacore::FITSImage::shape ( ) const
virtual

return the shape of the FITSImage

Implements casacore::LatticeBase.

virtual void casacore::FITSImage::showCacheStatistics ( ostream &  os) const
virtual

Report on cache success.

Reimplemented from casacore::LatticeBase.

virtual void casacore::FITSImage::tempClose ( )
virtual

Temporarily close the image.

Reimplemented from casacore::LatticeBase.

uInt casacore::FITSImage::whichHDU ( ) const
inline

Return the HDU number.
