Crate chordsketch_render_pdf 

PDF renderer for ChordPro documents.

Converts a parsed ChordPro AST into a PDF document. ASCII and Latin-1 characters are rendered using built-in Helvetica Type1 fonts. Characters outside the Latin-1 range (e.g. CJK, Greek, Cyrillic) are rendered with a bundled Noto Sans CJK JP subset font embedded as a CID composite font (Type0 / CIDFontType0C). Uses flate2 for PNG image decompression.

Supports multi-page output: content automatically flows to new pages when the current page overflows, and {new_page} / {new_physical_page} directives trigger explicit page breaks.

Constants

MAX_WARNINGS

Maximum number of warnings the renderer accumulates per render pass. Re-exported from chordsketch-chordpro::render_result so callers can keep importing chordsketch_render_pdf::MAX_WARNINGS unchanged (issue #1874). Maximum number of warnings any renderer accumulates for a single render pass (issue #1833). Without a cap, a pathological input such as one million malformed {transpose} lines would push the warnings vector to tens of megabytes. push_warning refuses to exceed this limit and appends a single truncation marker the first time the cap is hit.
