Referenced by FillQHisto(), FillTQHisto(), and RawDigit2D().

void evd::RawDataDrawer::GetRawDigits ( art::Event const &  evt, details::CacheID_t const &  new_timestamp  )

private

Makes sure raw::RawDigit's are available for the current settings.

Parameters

evt	event to read the digits from
ts	a cache ID assessing the new state the cache should move to

The function will ask the data cache for an update (RawDigitCacheDataClass::Update()). The cache will evaluate whether it is already in a state compatible with ts or if cache needs to be invalidated, in which case it will fill with new data. This method also triggers a Reset() if the target state differs from the old one.

		unsigned int	plane,
		bool	bZoomToRoI = false
	)

Draws raw digit content in 2D wire plane representation.

Parameters

evt	source for raw digits
view	target rendered object
plane	number of the plane to be drawn
bZoomToRoI	whether to render only te region of interest

This function performs pre-rendering of the raw digit content into a 2D view of the wire plane as TDC vs. wire number. The material for rendering is created and sent to view object for actual rendering. The pre-rendering result currently depends on information from the current rendering canvas, and in particular on its viewport in the (wire, TDC) space.

If no zoom to the region of interest is required, the region itself is computed (only if not known yet) while the rendering is performed. If the zoom is required instead, rendering is performed in two steps; in the first, run only of no region of interest is known yet, the region is extracted. In the second, that information is used for rendering.
