    Formula definition

    You can set QRCode sparkline 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.

    Using Code

    This example code sets a QRCode sparkline in the worksheet.

    Copy Code
    var sheet = spread.getActiveSheet();
    // Set QR Code Barcode Sparkline
    sheet.setValue(3, 1, "QR Code", GC.Spread.Sheets.SheetArea.viewport);
    sheet.setValue(3, 2, "Police:911", GC.Spread.Sheets.SheetArea.viewport);
    // Set Style
    sheet.setRowHeight(3, 100);
    for (var col = 1; col < 4; col++)
        sheet.setColumnWidth(col, 200);
    sheet.getRange(3, 0, 1, 4).hAlign(GC.Spread.Sheets.HorizontalAlign.center);
    sheet.getRange(3, 0, 1, 4).vAlign(GC.Spread.Sheets.VerticalAlign.center);
    // Set Formula
    sheet.setFormula(3, 3, '=BC_QRCODE(C4)');
