vtkSimpleImageToImageFilter
Section: Visualization Toolkit Filtering Classes
Usage
vtkSimpleImageToImageFilter is a filter which aims to avoid much
of the complexity associated with vtkImageAlgorithm (i.e.
support for pieces, multi-threaded operation). If you need to write
a simple image-image filter which operates on the whole input, use
this as the superclass. The subclass has to provide only an execute
method which takes input and output as arguments. Memory allocation
is handled in vtkSimpleImageToImageFilter. Also, you are guaranteed to
have a valid input in the Execute(input, output) method. By default,
this filter
requests it's input's whole extent and copies the input's information
(spacing, whole extent etc...) to the output. If the output's setup
is different (for example, if it performs some sort of sub-sampling),
ExecuteInformation has to be overwritten. As an example of how this
can be done, you can look at vtkImageShrink3D::ExecuteInformation.
For a complete example which uses templates to support generic data
types, see vtkSimpleImageToImageFilter.
To create an instance of class vtkSimpleImageToImageFilter, simply
invoke its constructor as follows
obj = vtkSimpleImageToImageFilter
