{!core.SimpleClientRect}
combineRects(rect1, rect2)
- Parameters:
- {!core.SimpleClientRect} rect1
- {!core.SimpleClientRect} rect2
- Returns:
- {!core.SimpleClientRect}
<inner>
{?core.SimpleClientRect}
growRect(originalRect, newRect)
- Parameters:
- {?core.SimpleClientRect} originalRect
- {?core.SimpleClientRect} newRect
- Returns:
- {?core.SimpleClientRect}
<inner>
{!boolean}
isLineBoundary(nextRect)
Returns true if the amount of overlap between the known line rectangle and the visible next rectangle
is below the specified MIN_OVERLAP_THRESHOLD. If there is no known line rectangle, this will return false.
- Parameters:
- {!core.SimpleClientRect} nextRect
- Client rect of next step (by direction)
- Returns:
- {!boolean}
{!boolean}
process(stepInfo, previousRect, nextRect)
- Parameters:
- {!gui.StepInfo} stepInfo
- {?ClientRect} previousRect
- {?ClientRect} nextRect
- Returns:
- {!boolean}
<inner>
{!number}
verticalOverlapPercent(rect1, rect2)
Return the fraction of overlap between two rectangles. If there is
no overlap, or either of the rectangles is 0 height, this will
return 0.
