vtkImageSeedConnectivity marks pixels connected to user supplied seeds. The input must be unsigned char, and the output is also unsigned char. If a seed supplied by the user does not have pixel value "InputTrueValue", then the image is scanned +x, +y, +z until a pixel is encountered with value "InputTrueValue". This new pixel is used as the seed . Any pixel with out value "InputTrueValue" is consider off. The output pixels values are 0 for any off pixel in input, "OutputTrueValue" for any pixels connected to seeds, and "OutputUnconnectedValue" for any on pixels not connected to seeds. The same seeds are used for all images in the image set.
To create an instance of class vtkImageSeedConnectivity, simply invoke its constructor as follows
obj = vtkImageSeedConnectivity
The class vtkImageSeedConnectivity has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, obj
is an instance of the vtkImageSeedConnectivity class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkImageSeedConnectivity = obj.NewInstance ()
vtkImageSeedConnectivity = obj.SafeDownCast (vtkObject o)
obj.RemoveAllSeeds ()
