◆ NIFTI_VERSION

#define NIFTI_VERSION (   h)
Value:
(((h).magic[0] == 'n' && (h).magic[3] == '\0' && ((h).magic[1] == 'i' || (h).magic[1] == '+') && \
((h).magic[2] >= '1' && (h).magic[2] <= '9')) \
? (h).magic[2] - '0' \
: 0)
Computes the portion of a dataset which is inside a selection.

Given a nifti_1_header struct, check if it has a good magic number. Returns NIFTI version number (1..9) if magic is good, 0 if it is not.

Definition at line 154 of file vtkNIFTIImagePrivate.h.

◆ NIFTI_ONEFILE

#define NIFTI_ONEFILE (   h)    ((h).magic[1] == '+')

Check if a nifti_1_header struct says if the data is stored in the same file or in a separate file. Returns 1 if the data is in the same file as the header, 0 if it is not.

Definition at line 165 of file vtkNIFTIImagePrivate.h.

◆ NIFTI_NEEDS_SWAP

#define NIFTI_NEEDS_SWAP (   h)    ((h).dim[0] < 0 || (h).dim[0] > 7)

Check if a nifti_1_header struct needs to be byte swapped. Returns 1 if it needs to be swapped, 0 if it does not.

Definition at line 171 of file vtkNIFTIImagePrivate.h.
