Functions
-
getSymbolSize(String symbol)
→ Tuple2<int, int>
-
Returns the rendered ink size
(width, height) of an FSW symbol key
(e.g. S2e748), measured in the Sutton SignWriting Line font at size 30.
-
signwritingBox(Sign sign)
→ Tuple2<int, int>
-
Recomputes a sign's bottom-right box corner
(maxX, maxY) from its symbols'
rendered sizes — the tight box used when trustBox is off.
-
symbolExists(String symbol)
→ bool
-
Whether an FSW symbol key corresponds to an existing ISWA glyph
(
width > 0 && height > 0). Malformed keys return false.
