No C library, no image library, and no network at runtime. You get an SVG document, or a PDF Form XObject content stream a report writer can place on a page. local zint = require "zint" local svg = zint.barcode({ barcode = "qrcode", data = "https://example.invalid/report", }) local form = zint.barcode({ barcode = 34, -- UPC-A data = "12345678901", filetype = "PDF", }) form.kind is "form-xobject". form.bbox, form.content, and form.resources are ready for the writer. The writer supplies the object number, the length, the Form dictionary, and the Do. This release draws these, by name or by id: Code 39 8 GS1-128 16 Code 128 20 Code 128 (suppress C) 60 Flattermarken 28 UPC-A 34 UPC-A, check digit supplied 35 EAN-8 10 EAN-13 15 UPC-E 37 UPC-E, check digit supplied 38 Interleaved 2 of 5 3 ITF-14 89 NVE-18 (SSCC) 75 QR Code 58 GS1 DataBar Omnidirectional 29 GS1 DataBar Stacked Omnidirectional 80 GS1 DataBar Expanded 31 GS1 DataBar Expanded Stacked 81 Data Matrix 71 PDF417 55 Compact PDF417 56 MaxiCode 57 USPS Intelligent Mail 85 Aztec 92 EAN-2 add-on 11 EAN-5 add-on 12 ISBN 69 EAN-13 takes 12 digits and appends the check digit, or 13 digits and checks the one you supplied. EAN-8 does the same with 7 or 8. UPC-E takes 6 digits, or 7 with a number system of 0 or 1. Id 38 requires the check digit. An EAN-8 add-on is drawn and warned as non-standard. Interleaved 2 of 5 takes digits. An odd count grows a leading zero. vers 1 appends a GS1 check digit and shows it. vers 2 appends it and leaves it off the human-readable line. ITF-14 takes up to 14 digits, pads to 13, and appends or checks the GS1 check digit. It draws a bearer box of 5 modules unless a box or bind is already set. ITF-14 always has a 10-module quiet zone. Interleaved 2 of 5 adds that zone only with quietzones. NVE-18 is the 18-digit SSCC, drawn as GS1-128. It takes up to 18 digits, pads to 17, and appends or checks the GS1 check digit. The command-line name is nve18. Its quiet zone is added with quietzones. GS1 DataBar Omnidirectional takes up to 14 digits. Thirteen are padded and the check digit is appended. Fourteen must include the right check digit. A (01), [01], or leading 01 of the right length is stripped. Stacked Omnidirectional is the same symbol in two rows and has no human-readable line. Neither variant has a quiet zone. --gs1 is refused. The short names are dbaromn and dbaromnstk. GS1 DataBar Expanded takes a GS1 element string. Expanded Stacked is the same symbol broken into rows. cols sets the columns per row (1 to 11, default 2). rows sets the maximum rows (2 to 11) when cols is omitted. Stacked symbols have no human-readable line. Neither variant has a quiet zone. The short names are dbarexp and dbarexpstk. Data Matrix takes bytes. The short name is datamatrix. It has no human-readable line. vers picks a size from 1 to 48. square keeps the symbol square. dmre allows the rectangular DMRE sizes. fast uses the look-ahead encodation. A 144x144 symbol uses the de-facto ECC arrangement unless dmiso144 is set. The quiet zone is one module on each side, and only with quietzones. gs1 encodes an element string. gssep stores the GS separator as data. init writes a reader-initialisation symbol and is refused in GS1 mode. dotty draws the modules as dots. EAN-2 and EAN-5 are the magazine add-ons, drawn on their own. The short names are ean2 and ean5. A short digit string is padded with leading zeroes. The same add-on can hang off an EAN-13, a UPC-A, or a UPC-E. ISBN is drawn as EAN-13. The short names are isbn and isbnx. An ISBN-13 must begin with 978 or 979. An ISBN-10 or a 9-digit SBN becomes 978 plus the body. The human-readable line is the EAN-13 digits. Code 128 suppress C is Code 128 that never uses code set C, so a run of digits stays in set A or B. The short names are code128ab and code128b. Its quiet zone is the same 10 modules as Code 128, and only with quietzones. Flattermarken draws one mark per digit and has no human-readable line. The short name is flat. It takes up to 128 digits and has no quiet zone. PDF417 takes bytes and has no human-readable line. The short name is pdf417. Compact PDF417 drops the right row indicator and the stop pattern. Its short names are pdf417comp and pdf417trunc. secure sets the error correction level from 0 to 8. The default lets the symbol choose. cols sets the data columns from 1 to 30. rows sets the rows from 3 to 90. The quiet zone is two modules on each side, and only with quietzones. MaxiCode draws a hexagonal grid and a bullseye. The short name is maxicode. It has no human-readable line. mode selects modes 2 to 6. With no mode and no primary message the symbol is mode 4. Modes 2 and 3 read primary. scmvv sets the Structured Carrier Message version. The quiet zone is one module on each side, and only with quietzones. dotty is refused. Aztec takes bytes. The short names are aztec and azteccode. It has no human-readable line and no quiet zone. vers picks a size from 1 to 36. Sizes 1 to 4 are compact. secure sets the error correction level from 1 to 4. The default is 2. gs1 encodes an element string. init writes a reader-initialisation symbol and is refused in GS1 mode. dotty draws the modules as dots. USPS Intelligent Mail takes a 20-digit tracking code, and an optional ZIP of 5, 9, or 11 digits after a hyphen. The short name is uspsimail. It has no human-readable line. The quiet zone is added with quietzones. UPC and EAN human-readable digits are placed at OCR-B advances. The report writer embeds OCR-B and uses those positions. The PDF form names Helvetica as a placeholder font. SVG draws those digits in the bundled OCR-B face and every other symbol in Arimo. lua-zint is the same library from the shell. Pass option values as strings. Not in this release: Code 93, MicroPDF417, the other postal symbols, and the other formats listed in the README. An unknown Application Identifier is Error 260 and a bad length is Error 259, and neither writes a file. A bad check digit or a bad date is Warning 261, and the symbol is still drawn. QR text that fits Latin-1 stays Latin-1. Shift JIS warns 760. Input that fits neither is drawn again under an automatic ECI and warns 222. An unknown filetype is Error 142. The PDF form names Helvetica and leaves the face to the report writer. See NOTICE. Needs Lua 5.5 or newer. The rock builds no C.
