compile-pdf-barcode 0.1.0

CompilePDF barcode producer — deterministic 1D/2D barcode + GS1 symbol rendering into PDFs.

compile-pdf-barcode

Deterministic barcode + GS1 symbol rendering for CompilePDF.

Draws 1D and 2D barcode symbols onto a PDF per a validated plan. CompilePDF is the only PDF writer in the Print With Synergy stack — this producer applies the barcode plan it is handed; it does not grade the symbol (codex's job) or decide pass/fail (lint's job).

Symbologies (1.0.0)

Symbology	Standard	Kind	Notes
code128	ISO/IEC 15417	1D	Auto subset B/C, computed checksum
ean13	ISO/IEC 15420	1D	12 digits + computed check, or 13 validated
upca	ISO/IEC 15420	1D	GTIN-12 subset of EAN-13
qr	ISO/IEC 18004	2D	Via segno; L/M/Q/H error correction

Determinism

Symbols are drawn as black-filled rectangle content streams (one rect per bar / per dark module), with fixed-decimal numeric formatting and stable rectangle ordering, then saved with Pdf.save(deterministic_id=True, linearize=False). Same input PDF + same plan → byte-identical output PDF (verified by the determinism layer in the verifier). The pure-Python segno QR generator is deterministic for a fixed payload + error level.

Service-skip (fail-fast)

The 2D (QR) lane requires segno. If it is not importable the producer fails fast with BARCODE_LIB_MISSING (HTTP 503) rather than emitting a PDF that lies about what was drawn — compile is a writer, not a silent skipper.

Install

uv pip install compile-pdf-barcode

Position in the stack

One of the CompilePDF producers (rewrite, marks, impose, trap, soft-proof, separations, white-underbase, barcode, …). Each lives in its own PyPI package; producers depend on compile-pdf-core, never on each other.

Scoped follow-ups

• GS1 application identifiers (SSCC/SGTIN AI bracket encoding, GS1-128 FNC1) — the schema accepts raw payloads today; AI-aware encoding is an additive 1.x.
• DataMatrix (incl. GS1 DataMatrix) — segno is QR-only; DataMatrix needs a separate deterministic encoder (additive 1.x, fails fast if its lib is absent).
