QRCode is a two dimensional barcode representing symbology that enables effective handling of numeric, alphanumeric and byte data. This barcode can encode up to 7,366 characters.
The below image displays QRCode barcode in a PDF document.
You can set QRCode in a worksheet using the following formula:
=BC_QRCODE(value, color, backgroundColor, errorCorrectionLevel, model, version, mask, connection, connectionNo, charCode, charset, quietZoneLeft, quietZoneRight, quietZoneTop, quietZoneBottom)
Name | Description |
---|---|
value | A string that represents encode on the symbol of QRCode. |
color | A color that represents the barcode color. The default value is 'rgb(0,0,0)'. |
backgroundColor | A color that represents the barcode backgroundcolor. The default value is 'rgb(255, 255, 255)' |
errorCorrectionLevel | A string that represents the error correction level of QRCode. It has 'L|M|Q|H' four error correction levels. The default value is 'L'. |
model | A value that represents the model of QRCode. It has 1 and 2 models. The default value is 2. |
version | Vesion range is 1-14 for model1 and model 2. It has 'auto|1-14|1-40' values. The default value is 'auto'. |
mask | A value that represents mask pattern for QRCode. It has 'auto and 0-7' eight mask pattern. |
connection | A value that represents whether the symbol is part of a structured append message. The default value is false. |
connectionNo | Specifies which block the symbol is in the structured append message. It has '0-15' values. The default value is '0'. |
charCode | A value that represents the collection of characters of QRCode. |
charset | A value that represents which charset to use. It has 'UTF-8 and Shift-JIS'. |
quietZoneLeft | A value that represents the size of left quiet zone. |
quietZoneRight | A value that represents the size of right quiet zone. |
quietZoneTop | A value that represents the size of top quiet zone. |
quietZoneBottom | A value that represents the size of bottom quiet zone. |
