## Member Function Documentation

vtkImageMathematics* vtkImageMathematics::New | ( |  | ) | `[static]`

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkImageMathematics::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkImageTwoInputFilter.

int vtkImageMathematics::IsTypeOf | ( | const char * | type | ) | `[static]`

| 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 vtkImageTwoInputFilter.

virtual int vtkImageMathematics::IsA | ( | const char * | type | ) | `[virtual]`
