vtkWarpLens is a filter that modifies point coordinates by moving in accord with a lens distortion model.
To create an instance of class vtkWarpLens, simply invoke its constructor as follows
obj = vtkWarpLens
The class vtkWarpLens 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 vtkWarpLens class. 
string = obj.GetClassName ()  int = obj.IsA (string name)  vtkWarpLens = obj.NewInstance ()  vtkWarpLens = obj.SafeDownCast (vtkObject o)  obj.SetKappa (double kappa) - Specify second order symmetric radial lens distortion parameter. This is obsoleted by newer instance variables.  double = obj.GetKappa () - Specify second order symmetric radial lens distortion parameter. This is obsoleted by newer instance variables.  obj.SetCenter (double centerX, double centerY) - Specify the center of radial distortion in pixels. This is obsoleted by newer instance variables.  double = obj.GetCenter () - Specify the center of radial distortion in pixels. This is obsoleted by newer instance variables.  obj.SetPrincipalPoint (double , double ) - Specify the calibrated principal point of the camera/lens  obj.SetPrincipalPoint (double a[2]) - Specify the calibrated principal point of the camera/lens  double = obj. GetPrincipalPoint () - Specify the calibrated principal point of the camera/lens  obj.SetK1 (double ) - Specify the symmetric radial distortion parameters for the lens  double = obj.GetK1 () - Specify the symmetric radial distortion parameters for the lens  obj.SetK2 (double ) - Specify the symmetric radial distortion parameters for the lens  double = obj.GetK2 () - Specify the symmetric radial distortion parameters for the lens  obj.SetP1 (double ) - Specify the decentering distortion parameters for the lens  double = obj.GetP1 () - Specify the decentering distortion parameters for the lens  obj.SetP2 (double ) - Specify the decentering distortion parameters for the lens  double = obj.GetP2 () - Specify the decentering distortion parameters for the lens  obj.SetFormatWidth (double ) - Specify the imager format width / height in mm  double = obj.GetFormatWidth () - Specify the imager format width / height in mm  obj.SetFormatHeight (double ) - Specify the imager format width / height in mm  double = obj.GetFormatHeight () - Specify the imager format width / height in mm  obj.SetImageWidth (int ) - Specify the image width / height in pixels  int = obj.GetImageWidth () - Specify the image width / height in pixels  obj.SetImageHeight (int ) - Specify the image width / height in pixels  int = obj.GetImageHeight () - Specify the image width / height in pixels
