Detailed Description

Flood fill an image region.

vtkImageThresholdConnectivity will perform a flood fill on an image, given upper and lower pixel intensity thresholds. It works similarly to vtkImageThreshold, but also allows the user to set seed points to limit the threshold operation to contiguous regions of the image. The filled region, or the "inside", will be passed through to the output by default, while the "outside" will be replaced with zeros. This behavior can be changed by using the ReplaceIn() and ReplaceOut() methods. The scalar type of the output is the same as the input.

protected

◆ FillInputPortInformation()

int vtkImageThresholdConnectivity::FillInputPortInformation ( int  port,
vtkInformation info

Reimplemented from vtkImageAlgorithm.

◆ RequestUpdateExtent()

int vtkImageThresholdConnectivity::RequestUpdateExtent ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
)
overrideprotectedvirtual

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

◆ RequestData()

int vtkImageThresholdConnectivity::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overrideprotectedvirtual

This is called in response to a REQUEST_DATA request from the executive.

Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.
