Macro Definition Documentation

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.

NIFTI_ONEFILE

(

h

)

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 )

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.
