Enum LineHeightAlignment 

pub enum LineHeightAlignment {
    Top,
    Center,
    Proportional,
    Bottom,
}

The line-height policy lives with the drawing-side text types, because a DrawScope has to be able to name it too: a run drawn through a canvas and a Text composable on the same screen must resolve their line boxes by the same rule, and the only style a draw scope can carry is the flat one from cranpose-ui-graphics. Where the leading — the difference between a line’s box and the font’s own ascent-plus-descent extent — is spent.

Variants

Top

All of it below the glyphs.

Center

Split evenly, with the odd whole pixel below the baseline.

Proportional

Split in the font’s own ascent-to-descent ratio.

Bottom

All of it above the glyphs.
