private static void testCODE39(Canvas canvas) throws Exception
{
    Code39 barcode = new Code39();
    
    /*
       Code39 Valid data char set:
            0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (Digits)
            A - Z (Uppercase letters)
            - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus)
    
       Code39 extension Valid data char set:
            All ASCII 128 characters
    */
    // Code39 encodes upper case chars only, for lower case chars, use Code 39 extension
    barcode.setData("123456789012");
    
    barcode.setExtension(false);
    
    barcode.setAddCheckSum(true);
    
    // Code 39 Wide Narrow bar Ratio
    // Valid value is from 2.0 to 3.0 inclusive.
    barcode.setN(3.0f);
    // The space between 2 characters in code 39; This a multiple of X; The default is 1.;
    // Valid value is from 1.0 (inclusive) to 5.3 (exclusive)
    barcode.setI(1.0f);
    barcode.setShowStartStopInText(true);
    
    // Unit of Measure, pixel, cm, or inch
    barcode.setUom(IBarcode.UOM_PIXEL);
    // barcode bar module width (X) in pixel
    barcode.setX(1f);
    // barcode bar module height (Y) in pixel
    barcode.setY(75f);
    
    // barcode image margins
    barcode.setLeftMargin(10f);
    barcode.setRightMargin(10f);
    barcode.setTopMargin(10f);
    barcode.setBottomMargin(10f);
    
    // barcode image resolution in dpi
    barcode.setResolution(72);
    
    // disply barcode encoding data below the barcode
    barcode.setShowText(true);
    // barcode encoding data font style
    barcode.setTextFont(new AndroidFont("Arial", Typeface.NORMAL, 12));
    // space between barcode and barcode encoding data
    barcode.setTextMargin(6);
    barcode.setTextColor(AndroidColor.black);
    
    // barcode bar color and background color in Android device
    barcode.setForeColor(AndroidColor.black);
    barcode.setBackColor(AndroidColor.white);
    
    RectF bounds = new RectF(30, 30, 0, 0);
    barcode.drawBarcode(canvas, bounds);
    
    GeneratedBarcodeInfo barInfo = barcode.getBarcodeInfo();
}
