#377 BarCodeReader and AVMetadataObjectTypeDataMatrixCode

[Knut Kjeilen]

I'm trying to scan Data Matrix barcodes in an app that I'm developing.

I added support for "AVMetadataObjectTypeDataMatrixCode" in DPF.iOS.BarCodeReader, method TDPFQRCodeScanner.CreateUIControl

---

ObjTypes := TNSMutableArray.Create; 
ObjTypes.addObject( ( AVMetadataObjectTypeDataMatrixCode  as ILocalObject ).GetObjectID );
..
LOutput.setMetadataObjectTypes( ObjTypes );
...

But with no luck - the demo-project is not able to detect Data Matrix codes.

Do you have any idea why AVMetadataObjectTypeDataMatrixCode is not working?
I'm using iOS 9.0.1 / Delphi Seattle - tried both 64bit and 32bit

Found the problem: I had to add support for the format in the delegate method TCaptureDelegate.captureOutput also.

if metadata.&type.isEqualToString( AVMetadataObjectTypeDataMatrixCode ) then begin
....invoke the component-event DoOnScan with the code
end;
