template<OperationReadyData DataType>

DataType MayaFlux::Yantra::transform_slice	(	DataType &	input,
		double	start_ratio,
		double	end_ratio,
		std::vector< std::vector< double > > &	working_buffer
	)

Slice transformation to extract a portion of the data based on ratios (OUT-OF-PLACE)

Template Parameters

DataType

OperationReadyData type

Parameters

input	Input data - will NOT be modified
start_ratio	Start ratio (0.0 to 1.0)
end_ratio	End ratio (0.0 to 1.0)
working_buffer	Buffer for operations (will be resized if needed)

Returns

Sliced data
