lua-zint-svg

Draw barcodes from Lua. 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:
