README.md

M6.1/M6.2: form filling: new fonts (L2) and forms (L3) crates; field tree with inheritance, widgets, options; set_value with validation and regenerated appearances (auto-size, comb, multiline, password, quadding, /MK, combo, list selection), check/radio states (own AP when missing), reset to /DV; engine SetFieldValue/ResetForm with fill-forms permission; UI in-place editor (Enter/click-away commit, Escape, Tab with select-all), check/radio toggle, choice popup, Clear form; tools form_fields/form_fill/form_reset. Perf: named destinations indexed once (190 MB manual opens in 1.8 s instead of 172 s); comment and form edits refresh view data from the object graph instead of a full re-inspection (6x faster per edit on large files; equivalence-tested). annot uses the shared fonts helpers. Docs, parity, roadmap.

printcraft-fonts

Layer L2. Font helpers for the appearance streams PrintCraft generates (comments, form fields).

Today it holds what generated appearances need without a font program:

helvetica_width: an approximation of Helvetica's proportions by character class. No metrics file or font program from any vendor is bundled; widths are PrintCraft's own estimates, good enough for line breaking and alignment, not for typesetting.
wrap: greedy line breaking with that measure (paragraphs on newlines, long words split).
win_ansi: Unicode → WinAnsiEncoding bytes (? for characters it can't represent), and literal to write bytes as a PDF literal string.

The full font subsystem (parsing, shaping, subsetting and embedding) arrives with M2.2/M7.
