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::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.

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]].

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. Propagate back up the pipeline for ports and trigger the update on the other side of the port to allow for asynchronous parallel processing in the pipeline.
