LabelRecognizerModule Class

The LabelRecognizerModule Class is defined in the namespace Dynamsoft.DLR.

getVersion

Returns the version of the LabelRecognizer module.

static getVersion(): string;

Code snippet

const version = Dynamsoft.DLR.LabelRecognizerModule.getVersion();
console.log(version);

loadRecognitionData

Loads a specific data file containing recognition information to aid in identifying text composed of predetermined characters. This file typically comprises a Convolutional Neural Networks (CNN) model.

static loadRecognitionData(dataName: string, dataPath?: string): Promise<void>;

Parameters

• dataName: specifies the name of the recognition data. Available values are “MRZ”, “VIN”, “Letter”, “Number”, “NumberLetter”, “UpperCase”, “NumberUppercase”.
• dataPath: specifies the path to find the data file. If not specified, the default path points to the package “dynamsoft-label-recognizer-data” which has the same root path as the package “dynamsoft-label-recognizer”.

Code snippet

await Dynamsoft.DLR.LabelRecognizerModule.loadRecognitionData("NumberLetter");

onDataLoadProgressChanged

An event that repeatedly fires during the loading of a recognition data file (.data).

static onDataLoadProgressChanged: (filePath: string, tag: "starting" | "in progress" | "completed", progress: { loaded: number, total: number }) => {};

Properties

• filePath: Returns the path of the recognition data file.
• tag: Indicates the ongoing status of the file download. Available values are “starting”, “in progress”, “completed”.
• progress: Shows the numerical progress of the download.

Code snippet

Dynamsoft.DLR.LabelRecognizerModule.onDataLoadProgressChanged = (filePath, tag, progress) => {
    console.log("The loading of the file " + filePath + " is " + tag +" ( " + progress.loaded + "/" + progress.total+ ").");
}
await Dynamsoft.DLR.LabelRecognizerModule.loadRecognitionData("NumberLetter");
