This function returns a bitfield describing what kinds of modifications have been made to the image during and since its initial encoding.

Parameters
scenethe area pertaining to this request
Returns
a bitfield itemizing the encoding modifications

Reimplemented from LTIImageFilter.

LT_STATUS LTITranslationFilter::initialize ( LTIImageStage srcImage,
