#include <vtkImageGradient.h>
Inheritance diagram for vtkImageGradient:
vtkImageGradient computes the gradient vector of an image. The vector results are stored as scalar components. The Dimensionality determines whether to perform a 2d or 3d gradient. The default is two dimensional XY gradient. OutputScalarType is always double. Gradient is computed using central differences.

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter. |

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkImageToImageFilter. |

If you want to compute the gradient of an arbitrary point scalar array, then set its name here. By default this in NULL and the filter will use the active scalar array. |

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method. Reimplemented from vtkImageToImageFilter. |
