Member Function Documentation

§ 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

scene the 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

scene the area pertaining to this request

Returns: a bitfield itemizing the encoding modifications

Reimplemented from LTIImageReader.
