Detailed Description

template<typename intT>
class ml::TSubImageBox< intT >

This class defines a rectangular subimage region of standard ML dimensions.

The subimage region is defined by two corners given by 2 objects of class TVector.

Thread-safety: This class is reentrant.

Notes:

operator= can safely be used although not implemented explicitly.
This class is used to describe subimage regions easily, portable and independent of the number of dimensions.

Example to initialize a subimage region:

SubImageBox loc;
loc.v1.x=0; loc.v1.y=0; loc.v1.z=0; loc.v1.c=0; loc.v1.t=0; loc.v1.u=0;
loc.v2.x=5; loc.v2.y=5; loc.v2.z=5; loc.v2.c=0; loc.v2.t=0; loc.v2.u=0;
 
// or alternatively
loc.v1 = ImageVector(0,0,0,0,0,0);
loc.v2 = ImageVector(5,5,5,0,0,0);
 
// or another alternative:
loc    = SubImageBox( ImageVector(0,0,0,0,0,0),ImageVector(5,5,5,0,0,0) );
