Propogate the computation of the maximum size of the pipeline. The second size returned is the estimated size of this data object according to the source. If this is structured data, then the source likely asked this object for its estimated size. If it is unstructured data, then the source should have made its own prediction as to its output size. The third size returned is the maximum pipeline size encounted upstream during this propagation.
All sizes are in kilobytes.
By default, there is no type specific information Reimplemented in vtkImageData . This method is called by the source when it executes to generate data. It is sort of the opposite of ReleaseData. It sets the DataReleased flag to 0, and sets a new UpdateTime. This number is valid only after the pipeline has updated.
