set() [1/2]

void Bspline_header::set	(	const float	img_origin[3],
		const float	img_spacing[3],
		const plm_long	img_dim[3],
		const plm_long	roi_offset[3],
		const plm_long	roi_dim[3],
		const plm_long	vox_per_rgn[3],
		const float	direction_cosines[9] )

Set the internal geometry.
This version of the function gets used when loading a B-Spline from file.

Parameters

img_origin	Image origin (in mm)
img_spacing	Image spacing (in mm)
img_dim	Image size (in vox)
roi_offset	Position of first vox in ROI (in vox)
roi_dim	Dimension of ROI (in vox)
vox_per_rgn	Knot spacing (in vox)
direction_cosines	Direction cosines

set() [2/2]

void Bspline_header::set	(	const Plm_image_header *	pih,
		const float	grid_spac[3] )

Set the internal geometry.
This version of the function gets used to calculate the geometry of an ALIGNED B-Spline with a specified grid spacing.

Parameters

pih	The image geometry associated with B-spline
grid_spac	The B-Spline grid spacing (in mm)

set_unaligned() [1/2]

void Bspline_header::set_unaligned	(	const float	img_origin[3],
		const float	img_spacing[3],
		const plm_long	img_dim[3],
		const plm_long	roi_offset[3],
		const plm_long	roi_dim[3],
		const float	grid_spac[3],
		const float	direction_cosines[9] )

Set the internal geometry.
This version of the function gets used to calculate the geometry of an UNALIGNED B-Spline with a specified grid spacing.

Parameters

pih	The image geometry associated with B-spline
grid_spac	The B-Spline grid spacing (in mm)

set_unaligned() [2/2]

void Bspline_header::set_unaligned	(	const Plm_image_header *	pih,
		const float	grid_spac[3] )

Set the internal geometry.
This version of the function gets used to calculate the geometry of an UNALIGNED B-Spline with a specified grid spacing.

Parameters

pih	The image geometry associated with B-spline
grid_spac	The B-Spline grid spacing (in mm)
