Detailed Description

Inner class referring to a subset of an image.

Currently must refer to the last dimension in the image, i.e., a volume in a 4D parent image, or a slice in a 3D image

Constructor & Destructor Documentation

RNifti::NiftiImage::Block::Block	(	const NiftiImage &	image,
		const int	dimension,
		const int	index
	)

inline

Standard constructor for this class.

Parameters

image	The parent image
dimension	The dimension along which the block applies (which should be the last)
index	The location along `dimension`

Exceptions

runtime_error If dimension is not the last dimension in the image

NiftiImageData RNifti::NiftiImage::Block::data ( ) const

inline

Obtain the data within the block.

template<typename TargetType >

std::vector<TargetType> RNifti::NiftiImage::Block::getData ( const bool useSlope = true ) const

Extract a vector of data from a block, casting it to any required element type.

Parameters

useSlope If true, the default, then the data will be adjusted for the slope and intercept stored with the image, if any

Note: If the slope and intercept are applied, there is no guarantee that the adjusted values will fit within the requested type. No check is made for this

Block& RNifti::NiftiImage::Block::operator= ( const NiftiImage & source )

inline

Copy assignment operator, which allows a block in one image to be replaced with the contents of another image.

Parameters

source A NiftiImage, containing the data to replace the block with

Exceptions

runtime_error If the source is incompatible with the block in size or datatype
