Process Params

Document processing

Multipage Processing

Multipage processing allows to read more than one page. Turn on/off multipage:

DocumentReader.setConfig({
  "processParams": {"multipageProcessing": true}
});

Info

If multipage processing is enabled, the SDK processes the front side of the document recognizes document type and checks in the database how many pages are available for this document. If there are any child documents (second page, back side) for this document type, multipage processing is triggered. It concerns scenarios which recognize document type.

The only exception is MrzAndLocate and Locate scenarios. In this case, if SDK detects an ID1-sized document, it will ask for the second page. Multi-page processing is not triggered for documents of other formats.

Double-page spread processing

Allows to process up to two pages of the document (so-called "a double-page spread") for one-shot if they are presented on the frame (image):

Info

This option is available for the following scenarios: DocType, Ocr, FullProcess, MrzOrBarcodeOrOcr, MrzOrOcr, LocateVisual_And_MrzOrOcr.

DocumentReader.setConfig({
  "processParams": {"doublePageSpread": true}
});

Authenticity

Allows you to define whether a document's holograms have to be checked:

DocumentReader.setConfig({
  "processParams": {"checkHologram": true}
});

Timeouts

Allows you to set the time limit for document recognition (in seconds), beyond which the recognition does not continue regardless of its result. The countdown starts from the moment the scenario starts:

DocumentReader.setConfig({
  "processParams": {"timeout": 20.0}
});

Allows you to set the time limit for document recognition (in seconds), beyond which the recognition does not continue regardless of its result. The countdown starts from the moment the document is detected:

DocumentReader.setConfig({
  "processParams": {"timeoutFromFirstDetect": 5.0}
});

Allows you to set the time limit for document recognition (in seconds), beyond which the recognition does not continue regardless of its result. The countdown starts from the moment the document type is recognized:

DocumentReader.setConfig({
  "processParams": {"timeoutFromFirstDocType": 3.0}
});

Display formats

You can change the format string of displayed dates in the results. Mask examples: "dd/mm/yyyy", "mm/dd/yyyy", "dd-mm-yyyy", "mm-dd-yyyy", "dd/mm/yy":

DocumentReader.setConfig({
  "processParams": {"dateFormat":  "dd-mm-yy"}
});

If you want to change the measure system, use one of the RGLMeasureSystem members:

DocumentReader.setConfig({
  "processParams": {"measureSystem":  RGLMeasureSystem.METRIC}
});

Logs

If set, Core logs will be written to the console:

DocumentReader.setConfig({
  "processParams": {"logs": true}
});

If set, deep logs will be saved (in case of reading problems). Turn on/off logs saving:

DocumentReader.setConfig({
  "processParams": {"debugSaveLogs": true}
});

If set, input images will be saved (in case of reading problems). Turn on/off images saving:

DocumentReader.setConfig({
  "processParams": {"debugSaveImages": true}
});

If set, input images will be cropped and saved. Turn on/off image saving:

DocumentReader.setConfig({
  "processParams": {"debugSaveCroppedImages": true}
});

Allows to save RFID session data to the file in binary format:

DocumentReader.setConfig({
  "processParams": {"debugSaveRFIDSession": true}
});

Scenario

DocumentReader.setConfig({
  "processParams": {"scenario": ScenarioIdentifier.SCENARIO_BARCODE}
});

You can assign a scenario to the Capture button. This scenario will be used if you press the button:

DocumentReader.setConfig({
  "processParams": {"captureButtonScenario": ScenarioIdentifier.SCENARIO_LOCATE}
});

Barcode types

Set the types of barcodes that you wish to process:

DocumentReader.setConfig({
  "processParams": {"barcodeTypes": [BarcodeType.PDF417, BarcodeType.QRCODE]}
});

There are documents that contain barcodes which data can be parsed only if document type verification is performed. The following property allows setting the barcode parser type which should be used during recognition. It allows parsing barcode data without performing document type verification:

DocumentReader.setConfig({
  "processParams": {"barcodeParserType": 123}
});

Filters

Set the list of the document ID's to process. All documents will be processed, if empty:

DocumentReader.setConfig({
  "processParams": {"documentIDList": [-274257313, -2004898043]}
});

If you read document which contains MRZ, all fields will be extracted. If you read document with OCR, you can set the list of field types that you wish to extract, other fields will be skipped during processing. All fields will be extracted, if the fieldTypesFilter is empty:

DocumentReader.setConfig({
  "processParams": {"fieldTypesFilter": [eVisualFieldType.FT_DATE_OF_EXPIRY]}
});

If set, in case required fields are not read, their values will be empty:

DocumentReader.setConfig({
  "processParams": {"checkRequiredTextFields": true}
});
