◆ getNumberOfInputBands()

ossim_uint32 ossimImageCacheTileSource::getNumberOfInputBands ( ) const

virtual

This method allows you to query the number of input bands.

If an image is band selectable this will allow one to select the bands you wish to read in. This indicates that the number of input bands might not match the number of output bands.

Returns: number of input bands.

Reimplemented from ossimImageCacheBase.

◆ getNumberOfOutputBands()

ossim_uint32 ossimImageCacheTileSource::getNumberOfOutputBands ( ) const

virtual

This method allows one to query the number of output bands.

This might not be the same as the n umber of input bands.

See also: getNumberOfInputBands().

Returns: number of output bands.

◆ getOutputScalarType()

ossimScalarType ossimImageCacheTileSource::getOutputScalarType ( ) const

virtual

This method allows you to query the scalar type of the output data.

This is simply the data type, i.e. whether its OSSIM_FLOAT, OSSIM_DOUBLE, OSSIM_UCHAR, ... etc. This means that if there are bands of different scalar types from a single image then they must be casted to the highest precision type.

See also: ossimConstants.h for all ossimScalarType.

Returns: The output scalar type.

This method is defined in the base class ossimObject.

This class overrides the default implementation to return its own short name.

Returns: The short name for this class as an ossimString.

ossimRefPtr< ossimImageData > ossimImageCacheTileSource::getTile	(	const ossimIrect &	rect,

virtual

Returns a pointer to an ossimImageDataObject given a rectangluar region of interest.

Parameters

rect	The region of interest to return.
resLevel	From which resolution set are we querying (default is 0 full res).

Returns: The ossimImageData object to the caller.

◆ getTile() [2/2]

bool ossimImageCacheTileSource::getTile	(	ossimImageData *	result,
		ossim_uint32	resLevel = `0`
	)

virtual

Method to get a tile.

Parameters

result The tile to stuff. Note The requested rectangle in full image space and bands should be set in the result tile prior to passing. It will be an error if: result.getNumberOfBands() != this->getNumberOfOutputBands()

Returns: true on success false on error. If return is false, result is undefined so caller should handle appropriately with makeBlank or whatever.

◆ open()

bool ossimImageCacheTileSource::open ( )

virtual

Pure virtual open.

Derived classes must implement.

Returns: Returns true on success, false on error.

Note: This method relies on the data member ossimImageData::theImageFile being set. Callers should do a "setFilename" prior to calling this method or use the ossimImageHandler::open that takes a file name and an entry index.
