rescaled()

ClipPosition tracktion::engine::ClipPosition::rescaled	(	TimePosition	anchorTime,

Member Data Documentation

time

TimeRange tracktion::engine::ClipPosition::time

The TimeRange this ClipPosition occupies.

Referenced by tracktion::engine::TrackItem::getEditTimeRange(), getEnd(), getLength(), getStart(), getStartOfSource(), operator==(), and rescaled().

offset

TimeDuration tracktion::engine::ClipPosition::offset = {}

The offset this ClipPosition has.

Offset is a bit unintuitive as the position this relates to in the source material will depend on lots of factors including looping and any time-stretching. It can generally be thought of as an offset from either the start of the file or the loop start position, scaled by any time-stretching.
