Member Function Documentation

static MrSIDImageStageManager* MrSIDImageStageManager::create ( void ) [static]

LT_STATUS MrSIDImageStageManager::createImageStage	(	lt_uint32	imageNumber,
		LTIImageStage *&	imageStage
	)		`[virtual]`

Note when done with the image stage call imageStage->release().

Parameters:

imageNumber	number of the image (zero based)
imageStage	a pointer to the created image stage

Reimplemented from LTIImageStageManager.

LT_STATUS MrSIDImageStageManager::createImageStage	(	lt_uint32	imageNumber,
		MrSIDSingleImageReaderBase *&	imageStage
	)

virtual LT_STATUS MrSIDImageStageManager::createMG2Reader	(	lt_uint32	imageNumber,
		MG2ImageReader *&	mg2Reader
	)		`[protected, virtual]`

virtual LT_STATUS MrSIDImageStageManager::createMG3Reader	(	lt_uint32	imageNumber,
		MG3SingleImageReader *&	mg3Reader
	)		`[protected, virtual]`

virtual LT_STATUS MrSIDImageStageManager::createMG4Reader	(	lt_uint32	imageNumber,
		MG4SingleImageReader *&	mg4Reader
	)		`[protected, virtual]`

LT_STATUS MrSIDImageStageManager::createOverviewImageStage ( LTIImageStage *& imageStage ) [virtual]

If an overview does not exsit this method returns LT_STS_Success and sets imageStage to NULL.

Parameters:

imageStage a pointer to the created image stage

Reimplemented from LTIImageStageManager.
