Detailed Description

IO Handler for Isis Cubes.

Author: 2003-02-14 Jeff Anderson

Member Enumeration Documentation

◆ Format

enum Isis::Cube::Format

These are the possible storage formats of ISIS cubes.

There is an internal IO handler for each one of these.

Enumerator

Bsq

Cubes are stored in band-sequential format, that is the order of the pixels in the file (on disk) is:

    S1,L1,B1
    S2,L1,B1
    and so on until ...
    SN,L1,B1
    S1,L2,B1
    and so on until ...
    S1,LN,B1
    S1,L1,B2
    S2,L1,B2
    and so on until ...
    S1,L1,BN

The idea is the cubes are stored left-to-right, top-to-bottom, then front-to-back.

Tile

Cubes are stored in tile format, that is the order of the pixels in the file (on disk) is BSQ within a given sub-area defined by the Tile IO handler.

Typically these tiles are around 1MB for efficiency.

The idea is the cubes are stored left-to-right, top-to-bottom inside the tiles (which have 1 band). The tiles are themselves in BSQ order also. Please note that this can cause cubes to be larger on disk due to the tile size not being evenly divisible into the cube size.

Cube:

------------------------------
|Tile *Tile *Tile *Tile *Tile|*
|  0  *  1  *  2  *  3  *  4 |*
|     *     *     *     *    |*
|****************************|*
|Tile *Tile *Tile *Tile *Tile|*
|  5  *  6  *  7  *  8  *  9 |*
|     *     *     *     *    |*
|****************************|*
|Tile *Tile *Tile *Tile *Tile|*
------------------------------*
* 10  * 11  * 12  * 13  * 14  *
*******************************

The symbol '*' denotes tile boundaries. The symbols '-' and '|' denote cube boundaries.

Constructor & Destructor Documentation

◆ Cube() [1/2]

Isis::Cube::Cube ( )

Constructs a Cube object.

◆ Cube() [2/2]

Isis::Cube::Cube	(	const FileName &	fileName,
		QString	access = `"r"`
	)

Construct a cube and open it for reading or reading/writing.

Parameters

fileName	Name of the cube file to open. Environment variables in the filename will be automatically expanded.
access	Defines how the cube will be opened. Either read-only "r" or read-write "rw".

References Isis::FileName::toString().

◆ ~Cube()

Isis::Cube::~Cube ( )

virtual

Destroys the Cube object.

Member Function Documentation

◆ addCachingAlgorithm()

void Isis::Cube::addCachingAlgorithm ( CubeCachingAlgorithm * algorithm )

This will add the given caching algorithm to the list of attempted caching algorithms.

The algorithms are tried in the opposite order that they were added - the first algorithm added is the last algorithm tried.

RegionalCachingAlgorithm is the only initial caching algorithm and works well for most cases. The caching algorithm only apply to the opened Cube and is reset by any changes to the open status of the Cube.

This method takes ownership of algorithm.

Parameters

algorithm The caching algorithm to add to the Cube for I/O

Optionally, it deletes the cube if requested.

Parameters

removeIt (Default value = false) Indicates if the file should be removed/deleted.
