detectEnvironment

Detect the current device environment.

detectEnvironment(): Promise<any>

Return Value

Promise<any>

Code snippet

Dynamsoft.CVR.CaptureVisionRouter.detectEnvironment();

preLoadModule

Loads the specified module to speed up the initialization.

Syntax

preLoadModule(moduleName: string | Array<string>): void

Parameter

moduleNameIt: It takes a string or an array of strings representing the module or modules to preload. Valid values for moduleName are ‘DBR’ (Dynamsoft Barcode Reader), ‘DLR’ (Dynamsoft Label Recognizer), ‘DDN’ (Dynamsoft Document Normalizer), and ‘DCP’ (Dynamsoft Code Parser).

Return value

None.

Code snippet

Dynamsoft.CVR.CaptureVisionRouter.preloadModule(["DBR"]);

isModuleLoaded

Returns whether the specified module has been loaded.

Syntax

isModuleLoaded(moduleName: string): boolean;

Parameter

moduleName: It takes a string representing the module to preload. Valid values for moduleName are ‘DBR’ (Dynamsoft Barcode Reader), ‘DLR’ (Dynamsoft Label Recognizer), ‘DDN’ (Dynamsoft Document Normalizer), and ‘DCP’ (Dynamsoft Code Parser).

Return value

A boolean value that indicates whether the required module has been loaded.

Code snippet

if(Dynamsoft.CVR.CaptureVisionRouter.isModuleLoaded('dbr')){
    // Use the router to perform a DBR job.
} else {
    console.log("DBR module is not preloaded.");
}

createInstance

Initializes a new instance of the CaptureVisionRouter class.

Syntax

createInstance(): Promise<CaptureVisionRouter>;

Parameter

None.

Return value

A promise that resolves with the initialized CaptureVisionRouter object.

Code snippet

let router = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();

dispose

Releases all resources used by the CaptureVisionRouter object.

Syntax

dispose(): Promise<void>;

Parameter

None.

Return value

Returns a promise that resolves when the resources have been successfully released.

Code snippet

let router = await Dynamsoft.CVR.CaptureVisionRouter.createInstance();
// Use the router to perform a job.
// ...
// Release the resources after the job is finished.
router.dispose();

disposed

Returns whether the CaptureVisionRouter object has been disposed of.

Syntax

disposed: boolean;

Parameter
