calculate_output_region() [1/2]

Region MayaFlux::Kakshya::calculate_output_region	(	const std::vector< uint64_t > &	current_pos,
		const std::vector< uint64_t > &	output_shape
	)

Calculate output region bounds from current position and shape.

Parameters

current_pos	Current position coordinates.
output_shape	Desired output shape.

Returns

Region representing the output bounds.
