Package Exports

qr-image

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (qr-image) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

qr.image(text, [ec_level | options]) — returns Readable stream with image data. qr.matrix(text, [ec_level]) — returns 2D array.

text — text to encode;
ec_level — error correction level. One of L, M, Q, H. Default M.
options — image options object:
- ec_level — default M.
- type — image type. Possible values png (default), svg (svgpath), pdf and eps.
