void vtkImageMultipleInputFilter::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

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 vtkImageSource.

Reimplemented in vtkImageMultipleInputOutputFilter, vtkImageTwoInputFilter, vtkPushImageFilterSample, vtkImageAppend, vtkImageBlend, vtkImageCheckerboard, vtkImageCorrelation, vtkImageDifference, vtkImageLogic, vtkImageMask, vtkImageMathematics, and vtkImageNonMaximumSuppression.

virtual void vtkImageMultipleInputFilter::SetInput | ( | int | num,
|  | vtkImageData * | input
| ) | `[virtual]`

|  | vtkImageData * | outData,
|  | int | extent[6],
|  | int | threadId
| ) | `[virtual]`

The execute method created by the subclass. This is kept public instead of protected since it is called from a non-member thread function.
