QRCodeFactory

qrcode(typeNumber, errorCorrectionLevel) => <code>QRCode</code>

Create a QRCode Object.

| Param | Type | Description | | ---------------------| ------------------- | ---------------------------------------------- | | typeNumber | <code>number</code> | Type number (1 ~ 40), or 0 for auto detection. | | errorCorrectionLevel | <code>string</code> | Error correction level ('L', 'M', 'Q', 'H') |

qrcode.stringToBytes(s) : <code>number[]</code>

Encodes a string into an array of number(byte) using any charset. This function is used by internal. Overwrite this function to encode using a multibyte charset.

| Param | Type | Description | | ------ | ------------------- | ---------------- | | s | <code>string</code> | string to encode |

QRCode

addData(data, mode) => <code>void</code>

Add a data to encode.

| Param | Type | Description | | ------ | ------------------- | ---------------------------------------------------------- | | data | <code>string</code> | string to encode | | mode | <code>string</code> | Mode ('Numeric', 'Alphanumeric', 'Byte'(default), 'Kanji') |

make() => <code>void</code>

Make a QR Code.

getModuleCount() => <code>number</code>

The number of modules(cells) for each orientation. [Note] call make() before this function.

isDark(row, col) => <code>boolean</code>

The module at row and col is dark or not. [Note] call make() before this function.

| Param | Type | Description | | ----- | ------------------- | ------------------- | | row | <code>number</code> | 0 ~ moduleCount - 1 | | col | <code>number</code> | 0 ~ moduleCount - 1 |

createDataURL(cellSize, margin) => <code>string</code>

createImgTag(cellSize, margin, alt) => <code>string</code>

createSvgTag(cellSize, margin) => <code>string</code>

createTableTag(cellSize, margin) => <code>string</code>

createASCII(cellSize, margin) => <code>string</code>

Helper functions for HTML. [Note] call make() before these functions.

| Param | Type | Description | | -------- | ------------------- | --------------------- | | cellSize | <code>number</code> | default: 2 | | margin | <code>number</code> | default: cellSize * 4 | | alt | <code>string</code> | (optional) |

createSvgTag(opts) => <code>string</code>

| Param | Type | Description | | ------------- | -------------------- | --------------------- | | opts | <code>object</code> | default: {} | | opts.cellSize | <code>number</code> | default: 2 | | opts.margin | <code>number</code> | default: cellSize * 4 | | opts.scalable | <code>boolean</code> | default: false |

renderTo2dContext(context, cellSize) => <code>void</code>
