Detailed Description

Resamples a 1D input field of size N to this element's output size M.

On each step(), Resize reads its input field's "output" component (size N) and resamples it to its own output size M using the configured InterpolationMethod (linear, nearest, or cubic). The output size is the element's own declared dimension; the input size is taken from the connected source. Because the input and output sizes differ, Resize overrides addInput() to size the "input" component to the source's size.

Constructor & Destructor Documentation

Resize()

dnf_composer::element::Resize::Resize	(	const ElementCommonParameters &	elementCommonParameters,
		const ResizeParameters &	parameters
	)
