buildCumY(rowHeights: number[], rowGap: number): number[]

Description

Builds cumulative vertical positions for rows with different heights.

Rows with zero height contribute no gap. An empty height array returns [0]. Heights and the gap must be non-negative. The final entry includes the gap after the last non-empty row.

Parameters

Return values

The row start positions in pixels followed by the total extent including any trailing gap.

Example

buildCumY([100, 0, 200], 10); // [0, 110, 110, 320]
