### How to use: First run: npm install --save qrcode-generator-es6 Then use it in your code like: import qrcode from 'qrcode-generator-es6'; const qr = new qrcode(0, 'H'); qr.addData('This is my data'); qr.make(); my_element.innerHTML = qr.createSvgTag({}); ## qrcode Displays a QR code. Set the code data with `addData` and, call `make` and then call `createSvgTag` or `createImgTag`. See `gallery.html` for an example. **Parameters** - `typeNumber` **integer** The minimum QR code type number from 1 to 40. Using 0 allows any QR code type number. - `errorCorrectionLevel` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** 'L','M','Q','H' ### isDark **Parameters** - `row` - `col` Returns **[boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** true if the module at `row, col` is dark. ### getModuleCount Returns **integer** The module count in one dimension of the QR code. The total number of modules is the square of this value. ### make Call this when done adding data before getting the generated QR code image. ### createSvgTag **Parameters** - `args` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)** - `args.drawCell` **[function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)?** A callback with arguments `column, row, x, y` to draw a cell. `x, y` are the coordinates to draw it at. `c, y` are the QR code module indexes. Returns the svg element child string for the cell. - `args.cellColor` **[function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)?** A callback which returns the color for the cell. By default, a function that returns `black`. Unused if `drawCell` is provided. - `args.margin` **integer?** The margin to draw around the QR code, by number of cells. - `args.obstruction` **[Object](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object)?** An image to place in the center of the QR code. - `args.obstruction.width` **integer** Width of the obstruction as a percentage of QR code width. - `args.obstruction.height` **integer** Height of the obstruction as a percentage of QR code height. - `args.obstruction.path` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** The path of the obstruction image. - `args.cellSize` Returns **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** An svg tag as a string. ### createImgTag **Parameters** - `cellSize` **integer** The size of a module in pixels. - `margin` **integer** The margin to draw around the QR code in pixels. Returns **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** An img tag as a string. ## stringToBytesFuncs ## stringToBytes ## QRMode ## QRErrorCorrectionLevel ## QRMaskPattern
