The class of a volume describes how the voxel data should be interpreted.
The most typical case is of a volume which has integer type, but the class
value ``real''. This corresponds to the typical MINC 1 file, which defined
scaling
- MI_CLASS_REAL - Floating point. The data are to be
interpreted as floating point values regardless of the storage type.
May be used with any integer or floating point type.
- MI_CLASS_INT - Integer. The data are to be interpreted as integer
values. May be used with any integer type.
- MI_CLASS_LABEL - Labeled or enumerated data. The values of
the voxels are assumed to be taken from a discrete set. These values
may be assigned a sybolic name to clarify the interpretation of the
data. May be used with any integer type.
- MI_CLASS_COMPLEX - Complex data. May be used with one of the
complex types only.
- MI_CLASS_UNIFORM_RECORD - A uniform record structure, essentially an
array with named entries.
- MI_CLASS_NON_UNIFORM_RECORD - A non uniform record structure. This
is not yet implemented.
