⚡ The Science Inside

How our Rust engine optimizes this specific format:

Dynamic-programming high-level encoder chooses Text/Numeric/Byte compaction for the smallest PDF417 payload.

  • • Exact cost model: 44 digits->15 codewords (numeric) and 6 bytes->5 codewords (byte) guides optimal splitting.
  • • Fast paths: long digit strings go straight to Numeric (no DP), and fully text-encodable inputs stay in Text mode.
  • • Auto-sizing chooses rows/cols for a ~3:1 aspect ratio, with user overrides and strict spec bounds validation.
  • • Reed-Solomon ECC uses a thread-local cached generator polynomial per security level (0-8) for speed.
  • • Renderer supports Compact (truncated) PDF417 and generates correct row indicators / clusters.
