openToStopLevel

layout openToStopLevel boolean { t | nil }

graphic openToStopLevel boolean { t | nil }

Description

Determines when the cellview data is loaded during rendering.

The default is t. All data is loaded to the window stop level (corresponding to the displayStopLevel variable), then rendered. All data is loaded, even data too small to see.

When set to nil, data loads on demand during rendering, to the displayResolution limit. This can slightly slow initial redraw, zooms or pans, but will dramatically reduce the amount of data loaded, since data too small to see is not rendered.
