template<typename T >

std::vector< std::vector< T > > MayaFlux::Kakshya::extract_region_data	(	const std::vector< std::span< const T > > &	source_data,
		const Region &	region,
		const std::vector< DataDimension > &	dimensions,
		bool	flatten = false
	)

Extract region data from planar storage (separate per channel/variant)

Template Parameters

T

Data type

Parameters

source_variants	Vector of data spans (one per channel/variant)
region	Region to extract
dimensions	Dimension descriptors
flatten	If true, return single flattened vector; if false, return per-channel vectors

Returns

Vector of vectors (per-channel) or single flattened vector
