§ getEncodingCost()

virtual lt_int64 MrSIDSingleImageReaderBase::getEncodingCost ( const LTIScene scene) const
virtual

Returns the "cost" to encode this scene, for use by those image writers which have usage metering enabled. The typical cost is equal to the nominal image size (width * height * numBands * bytesPerSample), but this is overridden for special situations, e.g. the mosaic filter.

Parameters
scenethe scene to be charged for
Returns
the cost to encode the given scene

Reimplemented from LTIImageReader.

§ getModifications()

virtual lt_uint32 MrSIDSingleImageReaderBase::getModifications ( const LTIScene scene) const
virtual

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 LTIImageReader.
