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:

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) );
VectorType v1
Corner v1 of the subimage region (included in region).
VectorType v2
Corner v2 of the subimage region (also included in region!).
TSubImageBox< MLint > SubImageBox
Define the standard SubImageBox type used in the ML. Its size varies with the size of the MLint type.
TImageVector< MLint > ImageVector
Defines the standard ImageVector type which is used by the ML for indexing and coordinates.

◆ clamp()

template<typename intT >
TImageVector< intT > ml::TSubImageBox< intT >::clamp ( const VectorType & position) const

Clamps the position to the nearest position inside the SubImageBox.

If the SubImageBox is empty, the result vector contains undefined values.

template<typename intT >
bool ml::TSubImageBox< intT >::contains ( const VectorType & position) const
inline

Returns true if position is inside the SubImageBox.

Definition at line 200 of file mlSubImageBox.h.

◆ correct()

template<typename intT >
void ml::TSubImageBox< intT >::correct ( )

Swaps all components where v1.

  • > v2.*. I.e., an empty vector becomes non empty if corresponding components are not equal.

template<typename intT >
static void ml::TSubImageBox< intT >::get3DCorners ( const TSubImageBox< intT > & box,
VectorType corners[8] )
inlinestatic

Returns the corners of the 3d box extents of box in corners.

All returned corners will be ImageVector(0) if box is empty. All c,t and u components are always set to 0.

VectorType ml::TSubImageBox< intT >::getExtent ( ) const
inline

Returns the extents of the subimage region.

If subimage region is empty then 0 is returned.

◆ getNumVoxels()

template<typename intT >
intT ml::TSubImageBox< intT >::getNumVoxels ( ) const
inline

Returns number of voxels in the subimage region, i.e., the product of all extents if this is not empty; otherwise 0 is returned.

Returns the overlapping region of subimage regions box1 and box2.

A result with (v1.x>v2.x || ... || v1.z>v1.z) is interpreted as empty! See also isEmpty(). This is especially true if that already holds for box1 or box2.
