Member Description

RebinImage ()

Default constructor (object useless)

RebinImage (const ImageInterface<T>&, const T& factors)

Constructor. The bin factors don't have to be integral. Anything left over at the end is treated as a full bin.

RebinImage (const RebinImage<T>& other)

Copy constructor (reference semantics).

virtual ~RebinImage()

RebinImage<T>& operator= (const RebinImage<T>& other)

Assignment (reference semantics).

virtual ImageInterface<T>* cloneII() const

Make a copy of the object (reference semantics).

virtual String imageType() const

Get the image type (returns name of derived class).

virtual Bool isMasked() const

Is the RebinImage masked? It is if its parent image is masked.

virtual Bool hasPixelMask() const

Does the image object have a pixelmask? It does if its parent has a pixelmask.

virtual const Lattice<Bool>& pixelMask() const
virtual Lattice<Bool>& pixelMask()

Get access to the pixelmask in use (thus to the pixelmask of the parent). An exception is thrown if the parent does not have a pixelmask.

virtual const LatticeRegion* getRegionPtr() const

Get the region used (always returns 0).

virtual Bool isPersistent() const

A RebinImage is not persistent.

virtual Bool isPaged() const

Is the RebinImage paged to disk?

virtual Bool isWritable() const

An RebinImage is not writable

virtual IPosition shape() const

Returns the shape of the RebinImage

virtual uInt advisedMaxPixels() const

This function returns the recommended maximum number of pixels to include in the cursor of an iterator.

virtual void resize(const TiledShape& newShape)

Function which changes the shape of the RebinImage. Throws an exception as resizing an RebinImage is not possible.

virtual String name (Bool stripPath=False) const

Return the name of the parent ImageInterface object.

virtual Bool ok() const

Check class invariants.

virtual Bool doGetSlice (Array<T>& buffer, const Slicer& section)

Do the actual getting of an array of values. Non-unit strides are not yet supported.

virtual void doPutSlice (const Array<T>& sourceBuffer, const IPosition& where, const IPosition& stride)

Putting data is not possible as the lattice is not writable.

virtual Bool doGetMaskSlice (Array<Bool>& buffer, const Slicer& section)

Get a section of the mask. Non-unit strides are not yet supported.

virtual LatticeIterInterface<T>* makeIter (const T& navigator, Bool useRef) const

This function is used by the LatticeIterator class to generate an iterator of the correct type for this Lattice. Not recommended for general use.

virtual IPosition doNiceCursorShape (uInt maxPixels) const

Get the best cursor shape.

virtual Bool lock (FileLocker::LockType, uInt nattempts)
virtual void unlock()
virtual Bool hasLock (FileLocker::LockType) const
virtual void resync()
virtual void flush()
virtual void tempClose()
virtual void reopen()

Handle the (un)locking and syncing, etc..

CoordinateSystem makeOutputCoordinates (const IPosition& factors, const CoordinateSystem& cSysIn, const IPosition& shapeIn, const IPosition& shapeOut)

Make CS
