obj.Write () - The main interface which triggers the writer to start.
obj.SetWriteToMemory (int ) - Write the image to memory (a vtkUnsignedCharArray)
int = obj.GetWriteToMemory () - Write the image to memory (a vtkUnsignedCharArray)
obj.WriteToMemoryOn () - Write the image to memory (a vtkUnsignedCharArray)
obj.WriteToMemoryOff () - Write the image to memory (a vtkUnsignedCharArray)
obj.SetResult (vtkUnsignedCharArray ) - When writing to memory this is the result, it will be NULL until the data is written the first time
vtkUnsignedCharArray = obj.GetResult () - When writing to memory this is the result, it will be NULL until the data is written the first time
