Defined in:

lib/fontisan/subset/table_strategy/maxp.rb

Overview

Maxp strategy: rewrite numGlyphs (offset 4, uint16) to the subset's glyph count. The remaining maxp fields describe worst- case outline/instruction complexity and can be left as-is — a smaller subset cannot exceed the source's maxima.

Class Method Summary

• .call(context:, tag:, table:) ⇒ String

  Binary maxp bytes for the subset.
