Detailed Description

efficient description of an image stencil

vtkImageStencilData describes an image stencil in a manner which is efficient both in terms of speed and storage space. The stencil extents are stored for each x-row across the image (multiple extents per row if necessary) and can be retrieved via the GetNextExtent() method.

int vtkImageStencilData::GetExtentType ( )
inlinevirtual

The extent type is 3D, just like vtkImageData.

Reimplemented from vtkDataObject.

Definition at line 53 of file vtkImageStencilData.h.

int vtkImageStencilData::GetNextExtent ( int &  r1,
int &  r2,
int  xMin,
int  xMax,
int  yIdx,
int  zIdx,
int &  iter 
)

Given the total output x extent [xMin,xMax] and the current y, z indices, return each sub-extent [r1,r2] that lies within within the unclipped region in sequence. A value of '0' is returned if no more sub-extents are available. The variable 'iter' must be initialized to zero before the first call, unless you want the complementary sub-extents in which case you must initialize 'iter' to -1. The variable 'iter' is used internally to keep track of which sub-extent should be returned next.

int vtkImageStencilData::IsInside ( int  xIdx,
int  yIdx,
int  zIdx 
)

Checks if an index is inside the stencil. This can be faster than GetNextExtent if called on a voxel. If calling sequentially, along a scan line, the preferred way is to use GetNextExtent and then loop over the returned [r1,r2] extents.

void vtkImageStencilData::InsertNextExtent ( int  r1,
int  r2,
int  yIdx,
int  zIdx 
)

This method is used by vtkImageStencilDataSource to add an x sub extent [r1,r2] for the x row (yIdx,zIdx). The specified sub extent must not intersect any other sub extents along the same x row. As well, r1 and r2 must both be within the total x extent [Extent[0],Extent[1]].

void vtkImageStencilData::InsertAndMergeExtent ( int  r1,
int  r2,
int  yIdx,
int  zIdx 
)

Similar to InsertNextExtent, except that the extent (r1,r2) at yIdx, zIdx is merged with other extents, (if any) on that row. So a unique extent may not necessarily be added. For instance, if an extent [5,11] already exists adding an extent, [7,9] will not affect the stencil. Likewise adding [10, 13] will replace the existing extent with [5,13].

void vtkImageStencilData::RemoveExtent ( int  r1,
int  r2,
int  yIdx,
int  zIdx 
)

Remove the extent from (r1,r2) at yIdx, zIdx

virtual void vtkImageStencilData::SetSpacing ( double  ,
