Limitations

Timeouts

Use the parameter to set the time limit (in seconds) for the document recognition, beyond which the recognition does not continue regardless of its result.

You can define the moment for the countdown to start.

• Start the countdown from the moment the scenario starts:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.timeout = 20

[RGLDocReader shared].processParams.timeout = @20;

DocumentReader.Instance().processParams().timeout = 20.0

DocumentReader.Instance().processParams().timeout = 20.0;

DocumentReader.instance.processParams.timeout = 20;

DocumentReader.setProcessParams({
    timeout: 20.0
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    timeout: 20.0
});

DocumentReader.setProcessParams({
    timeout: 20.0
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().Timeout = (Java.Lang.Double)20.0;

// iOS
RGLDocReader.Shared.ProcessParams.Timeout = 20.0;

• Start the countdown from the moment the document is detected:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.timeoutFromFirstDetect = 5

[RGLDocReader shared].processParams.timeoutFromFirstDetect = @5;

DocumentReader.Instance().processParams().timeoutFromFirstDetect = 5.0

DocumentReader.Instance().processParams().timeoutFromFirstDetect = 5.0;

DocumentReader.instance.processParams.timeoutFromFirstDetect = 5;

DocumentReader.setProcessParams({
    timeoutFromFirstDetect: 5.0
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    timeoutFromFirstDetect: 5.0
});

DocumentReader.setProcessParams({
    timeoutFromFirstDetect: 5.0
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().TimeoutFromFirstDetect = (Java.Lang.Double)5.0;

// iOS
RGLDocReader.Shared.ProcessParams.TimeoutFromFirstDetect = 5.0;

• Start the countdown from the moment the document type is recognized:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.timeoutFromFirstDocType = 3

[RGLDocReader shared].processParams.timeoutFromFirstDocType = @3;

DocumentReader.Instance().processParams().timeoutFromFirstDocType = 3.0

DocumentReader.Instance().processParams().timeoutFromFirstDocType = 3.0;

DocumentReader.instance.processParams.timeoutFromFirstDocType = 3;

DocumentReader.setProcessParams({
    timeoutFromFirstDocType: 3.0
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    timeoutFromFirstDocType: 3.0
});

DocumentReader.setProcessParams({
    timeoutFromFirstDocType: 3.0
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().TimeoutFromFirstDocType = (Java.Lang.Double)3.0;

// iOS
RGLDocReader.Shared.ProcessParams.TimeoutFromFirstDocType = 3.0;

Barcode recognition

Set the types of barcodes to process:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.barcodeTypes = [BarcodeType.QRCODE.rawValue as NSNumber, BarcodeType.AZTEC.rawValue as NSNumber]

[RGLDocReader shared].processParams.barcodeTypes = @[@(RGLBarcodeTypeQRCODE), @(RGLBarcodeTypeAZTEC)];

DocumentReader.Instance().processParams().doBarcodes = arrayOf(BarcodeType.valueOf(BarcodeType.PDF417), BarcodeType.valueOf(BarcodeType.QRCODE))

DocumentReader.Instance().processParams().doBarcodes = new String[]{BarcodeType.valueOf(BarcodeType.PDF417), BarcodeType.valueOf(BarcodeType.QRCODE)};

DocumentReader.instance.processParams.barcodeTypes = [
  BarcodeType.PDF417,
  BarcodeType.QRCODE
];

DocumentReader.setProcessParams({
    barcodeTypes: [BarcodeType.PDF417, BarcodeType.QRCODE]
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    barcodeTypes: [Enum.BarcodeType.PDF417, Enum.BarcodeType.QRCODE]
});

DocumentReader.setProcessParams({
    barcodeTypes: [DocumentReader.Enum.BarcodeType.PDF417, DocumentReader.Enum.BarcodeType.QRCODE]
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().DoBarcodes = new String[] { BarcodeType.ValueOf(BarcodeType.Pdf417), BarcodeType.ValueOf(BarcodeType.Qrcode) };

// iOS
RGLDocReader.Shared.ProcessParams.BarcodeTypes = new NSNumber[] { (int)RGLBarcodeType.Pdf417, (int)RGLBarcodeType.Qrcode };

Document recognition

• Set the list of the document IDs to process. If left empty, all documents are processed:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.documentIDList = [-274257313, -2004898043]

[RGLDocReader shared].processParams.documentIDList = @[@(-274257313), @(-2004898043)];

DocumentReader.Instance().processParams().documentIDList = intArrayOf(-274257313, -2004898043)

DocumentReader.Instance().processParams().documentIDList = new int[]{-274257313, -2004898043};

DocumentReader.instance.processParams.documentIDList = [
  -274257313,
  -2004898043
];

DocumentReader.setProcessParams({
    documentIDList: [-274257313, -2004898043]
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    documentIDList: [-274257313, -2004898043]
});

DocumentReader.setProcessParams({
    documentIDList: [-274257313, -2004898043]
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().DocumentIDList = new int[] { -274257313, -2004898043 };

// iOS
RGLDocReader.Shared.ProcessParams.DocumentIDList = new NSNumber[] { -274257313, -2004898043 };

• Set the minimum acceptable DPI value:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.minDPI = 100

[RGLDocReader shared].processParams.minDPI = @100;

DocumentReader.Instance().processParams().minDPI = 100

DocumentReader.Instance().processParams().minDPI = 100;

DocumentReader.instance.processParams.minDPI = 100;

DocumentReader.setProcessParams({
    minDPI: 100
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    minDPI: 100
});

DocumentReader.setProcessParams({
    minDPI: 100
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().MinDPI = (Java.Lang.Integer)100;

// iOS
RGLDocReader.Shared.ProcessParams.MinDPI = 100;

• Use a specific template ID and skip the document type identification step:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.forceDocID = 123

RGLDocReader.shared.processParams.forceDocID = @123;

DocumentReader.Instance().processParams().forceDocID = 123

DocumentReader.Instance().processParams().forceDocID = 123;

DocumentReader.instance.processParams.forceDocID = 123;

DocumentReader.setProcessParams({
    forceDocID: 123
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    forceDocID: 123
});

DocumentReader.setProcessParams({
    forceDocID: 123
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().ForceDocID = (Java.Lang.Integer)123;

// iOS
RGLDocReader.Shared.ProcessParams.ForceDocID = 123;

• Ignore assumptions based on the field mask in the template:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.matchTextFieldMask = true

RGLDocReader.shared.processParams.matchTextFieldMask = @YES;

DocumentReader.Instance().processParams().matchTextFieldMask = true

DocumentReader.Instance().processParams().matchTextFieldMask = true;

DocumentReader.instance.processParams.matchTextFieldMask = true;

DocumentReader.setProcessParams({
    matchTextFieldMask: true
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    matchTextFieldMask: true
});

DocumentReader.setProcessParams({
    matchTextFieldMask: true
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().MatchTextFieldMask = (Java.Lang.Boolean)true;

// iOS
RGLDocReader.Shared.ProcessParams.MatchTextFieldMask = true;

• Guarantee that an output image contains the correct MRZ on it in the series process mode:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.forceReadMrzBeforeLocate = true

RGLDocReader.shared.processParams.forceReadMrzBeforeLocate = @YES;

DocumentReader.Instance().processParams().forceReadMrzBeforeLocate = true

DocumentReader.Instance().processParams().forceReadMrzBeforeLocate = true;

DocumentReader.instance.processParams.forceReadMrzBeforeLocate = true;

DocumentReader.setProcessParams({
    forceReadMrzBeforeLocate: true
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    forceReadMrzBeforeLocate: true
});

DocumentReader.setProcessParams({
    forceReadMrzBeforeLocate: true
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().ForceReadMrzBeforeLocate = (Java.Lang.Boolean)true;

// iOS
RGLDocReader.Shared.ProcessParams.ForceReadMrzBeforeLocate = true;

• Limit MRZ formats to be recognized by specifying them in array:

SwiftObjective-C Kotlin Java Flutter React Native Ionic Cordova.NET MAUI

DocReader.shared.processParams.mrzFormatsFilter = [MRZFormat.ID2.rawValue as NSNumber, MRZFormat.ID1.rawValue as NSNumber]

RGLDocReader.shared.processParams.mrzFormatsFilter = @[@(RGLMRZFormatID2), @(RGLMRZFormatID1)];

DocumentReader.Instance().processParams().mrzFormatsFilter = arrayOf(MRZFormat.FORMAT_2X44, MRZFormat.FORMAT_3X30)

DocumentReader.Instance().processParams().mrzFormatsFilter = new String[]{MRZFormat.FORMAT_2X44, MRZFormat.FORMAT_3X30};

DocumentReader.instance.processParams.mrzFormatsFilter = [
  MRZFormat.FORMAT_2X44,
  MRZFormat.FORMAT_3X30
];

DocumentReader.setProcessParams({
    mrzFormatsFilter: [MRZFormat.ID2, MRZFormat.ID1]
}, (str) => { console.log(str) }, (error) => { console.log(error) });

DocumentReader.setProcessParams({
    mrzFormatsFilter: [MRZFormat.ID2, MRZFormat.ID1]
});

DocumentReader.setProcessParams({
    mrzFormatsFilter: [MRZFormat.ID2, MRZFormat.ID1]
}, function (m) { }, function (e) { console.log(e); });

// Android
DocumentReader.Instance().ProcessParams().MrzFormatsFilter = new string[] { MRZFormat.Format2x44, MRZFormat.Format3x30 };

// iOS
RGLDocReader.Shared.ProcessParams.MrzFormatsFilter = new NSNumber[] { (int)RGLMRZFormat.Id2, (int)RGLMRZFormat.Id1 };
