Documentation

Overview

Package preview is used to emulate a ROM for a short period of time in order to gather information that would takes time to acquire.

For example, it is used to determine the initial framing for the television on startup. Without a preview emulation the default framing will most often be wrong, resulting in a visible change in the image.
