DimLayout typedef

DimLayout = ({(Vector2, Vector2) ext0, (Vector2, Vector2) ext1, Vector2 n, Vector2 q0, Vector2 q1, (Vector2, Vector2) slash0, (Vector2, Vector2) slash1, String text, double textAngle, Vector2 textAt, double textHeight, Vector2 u, double value})

One dimension's geometry in world (spec 11 D6-D8), from layoutDimension:

• value: what it measures, never negative; text, its format in the page's unit with the page's decimal separator;
• u, n: the measuring direction and its left normal;
• q0, q1: the dimension line's ends;
• ext0, ext1: the extension lines at a and b, (start, end);
• slash0, slash1: the slashes about q0 and q1;
• textAt, textAngle (radians), textHeight: the value's insertion point, world angle and cap height.
