You should also be able to get them from your distro. \n\n## Library\nThe library can be used via the exported functions `createQRCode`, `byteStringToQR` and `readQRString`, plus their signed counterparts. The first two export to \".png\" while the third can be used on any image format `Zbar` supports.\n\nThe functions `bsToImg` and `objToImg` output JuicyPixels images for your further manipulation.\n\n### Use\n\nCompiling will generate an executable called `qrpipe` which reads from `stdin` and outputs a file as the second argument, e.g.\n\n```\necho 'My name is: Vanessa\" | qrpipe write -v \"nametag.png\"\n```\n\nTo then read the nametag:\n\n```\nqrpipe read \"nametag.png\"\n```\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvmchale%2Fqr-writer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvmchale%2Fqr-writer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvmchale%2Fqr-writer/lists"}
