I have this 3 situations: BarCode1.jpg : 2 Barcodes code 128 and 2 Barcodes 39=>All codes are read correctly
CODE_39[39;210;327;210] : ABC-1234
CODE_128[33;105;319;105] : ABC-abc-1234
CODE_128[424;52;600;52] : 123456787
CODE_39[404;213;628;213] : 123456
BarCode2.jpg : 2 Barcodes code 128 (1 horizontal and 1 vertical) and 2 Barcodes 39(1 horizontal and 1 vertical)=>Only horizontal codes are read correctly
CODE_39[39;210;327;210] : ABC-1234
CODE_128[33;105;319;105] : ABC-abc-1234
BarCode3.jpg : 2 Barcodes code 128 (1 horizontal and 1 vertical) and 3 Barcodes 39(2 horizontal and 1 vertical)=>Only horizontal codes are read correctly and the duplicate code was ignored.
CODE_39[39;267;327;267] : ABC-1234
CODE_128[33;133;319;133] : ABC-abc-1234
My code is very simple
private string ScanBarcode(Bitmap bitmap)
{
Bitmap target;
var reader = new ZXing.Windows.Compatibility.BarcodeReader()
{
AutoRotate = true,
Options = new DecodingOptions
{
TryHarder = true,
PureBarcode = false,
ReturnCodabarStartEnd = true,
}
};
Result[] result = reader.DecodeMultiple(bitmap);
if (result==null) return "not found";
string barcodeResult = "";
foreach (var res in result)
{
barcodeResult += res.BarcodeFormat.ToString() +"[" +res.ResultPoints[0].X +";"+ res.ResultPoints[0].Y +";" +res.ResultPoints[1].X + ";" + res.ResultPoints[1].Y + "]" + " : " + res.Text + "\r\n";
}
return barcodeResult;
}
I'm using ZXing.Windows.Compatibility (0.16.13.0) and ZXing (0.16.10.0)
My questions are:
- Exists an option to force read all barcodes regardless of orientation?
- Exists an option to force read all barcodes regardless of whether they are duplicated?
The case of duplication is weird but we have some forms where the same barcode is duplicated, I think, for redundancy reasons if the form is scratched out, but I would still like to get the position of both barcodes.
Thanks
