Detailed Description

The two most common uses of this class are passing a set of images to the LTIMosaicFilter and a wrapper around image formats that support multiple images in one file.

LTIImageStageManager was first added to replace the static list of LTIImageStage * passed to the LTIMosaicFilter to fix memory and file handle resource limitations.

Member Function Documentation

virtual LT_STATUS LTIImageStageManager::createImageProps ( lt_uint32  imageNumber,
LTIImage *&  imageProps 
) [virtual]

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

Parameters:
imageNumber number of the image (zero based)
image a pointer to the created image properties
virtual LTIImageStage* LTIImageStageManager::createImageStage ( lt_uint32  imageNumber  )  [virtual]
virtual LT_STATUS LTIImageStageManager::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 in MrSIDImageStageManager, and LizardTech::NITFReaderManager.

virtual LT_STATUS LTIImageStageManager::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 in MrSIDImageStageManager.
