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.
