eSCL device manager

In This Topic

eSCL is a driverless scanning protocol developed by the Mopria Alliance. eSCL is a RESTful interface to scanners, designed to simplify client-side scanning by requiring only the specification of an intent.

VintaSoft TWAIN .NET SDK provides the eSCL device manager that provides access to the eSCL devices.

For working with eSCL device manager it is necessary to create an instance of EsclDeviceManager class.

Here is an example that demonstrates how to open eSCL device manager and display information about all available eSCL devices:

/// <summary>
/// Opens eSCL device manager and displays information about available local eSCL image scanners.
/// </summary>
void GetEsclDevicesInfo()
{
    // create eSCL device manager
    using (Vintasoft.EsclImageScanning.EsclDeviceManager deviceManager = new Vintasoft.EsclImageScanning.EsclDeviceManager())
    {
        // open device manager
        deviceManager.Open();

        // wait while the eSCL device manager searches for eSCL devices
        System.Threading.Thread.Sleep(deviceManager.DeviceSearchTimeout);
        // get count of eSCL devices
        int deviceCount = deviceManager.Devices.Count;
        if (deviceCount == 0)
        {
            System.Console.WriteLine("Devices are not found.");
            return;
        }

        Vintasoft.EsclImageScanning.EsclDeviceCollection devices = deviceManager.Devices;
        // for each eSCL device
        for (int i = 0; i < devices.Count; i++)
        {
            // output the device name
            System.Console.WriteLine(string.Format("Device '{0}'", devices[i].Name));
        }
    }
}
