Sample code and features for AnyCpu or X86

What is Bridgex86?

Bridgex86 mode is our workaround for a problem of using TwainScanning with 32-bit scanner drivers in 64-bit applications. Previously, that wasn't possible because 64-bit applications can't work with 32-bit scanner drivers but with our Bridgex86 it is possible.

Bridgex86 has less functionality than our standard 32-bit library but supports the most important ones. Also, has a different workflow and it is more simple to use.

EXAMPLES OF Bridgex86 USE

Scanners

This example will list all installed scanners and the default scanner.


    var allScannersResult = Bridgex86.GetAllDevices(); // gets all installed scanners
    if (allScannersResult.Status == StatusType.OK)
    {
        Console.WriteLine("Found scanners:");
        foreach (var scanner in allScannersResult.Value) // Value property holds all scanners
            Console.WriteLine(scanner);
    }
    else
    {
        Console.WriteLine("No scanners found!");
    }

    var defaultScannerResult = Bridgex86.GetDefaultDevice(); // gets the default scanner
    if (defaultScannerResult.Status == StatusType.OK)
    {
        Console.WriteLine("Default scanner is: " + defaultScannerResult.Value); // Value property can also be a single value
    }
    else
    {
        Console.WriteLine("No default scanner found!");
    }

Get all scanner capabilites and check if capability exists

In this sample, we will get all the supported scanner capabilities and check if support for specific capability exists.


    // if scanner is omitted then the default scanner is used
    var allCapsResult = Bridgex86.GetAllSupportedCapabilities(scanner); // gets all supported capabilities
    Console.WriteLine("Supported capabilities:");
    foreach (var cap in allCapsResult.Value) // Value property holds all supported capabilities
        Console.WriteLine(cap);

    var pageSupportResult = Bridgex86.GetIsSupportedCapability("PageSize", scanner); // check support for specific capability, alias can also be used
    bool isSupported = pageSupportResult.Value; // check Value property to see if supported
    if (isSupported)
        Console.WriteLine("It's supported");
    else
        Console.WriteLine("It's not supported");

    var pagesResult = Bridgex86.GetSupportedPageSizes(scanner); // get all supported values for capability by using dedicated method
    Console.WriteLine("Supported pages:");
    foreach (var page in pagesResult.Value) // Value property holds all supported page sizes
        Console.WriteLine(page);

Scanning

Here we will cover a few scanning situations like adjusting scan settings, setting the desired scanner, modifying output file name, checking status, and displaying related messages.


    string scanner = "MyScanner";
    string outputFileName = @"C:\SomeFolder\Some\name.jpeg";

    var settings = new ScanSettings(); // holds all scan settings, if omitted scanner defaults are used
    settings.Device = scanner; // default scanner is used if omitted
    settings.TransferMechanism = TwSX.Native;
    var pgCap = Bridgex86.GetSupportedPageSizes(scanner);
    settings.PageSize = (TwSS)Enum.Parse(typeof(TwSS), pgCap.Value[0]); // some values require parsing

    var scanResult = Bridgex86.Acquire(outputFileName, settings);

    // check status and display related messages
    if (scanResult.Status == StatusType.OK)
    {
        Console.WriteLine("Scan successful!");
    }
    else if (scanResult.Status == StatusType.Warning)
    {
        Console.WriteLine("Scan warnings:");
        Console.WriteLine(scanResult.WarningMessages);
    }
    else if (scanResult.Status == StatusType.Error)
    {
        Console.WriteLine("Scan errors:");
        Console.WriteLine(scanResult.ErrorMessages);
    }
    else
    {
        Console.WriteLine("Unknown issue during scan!");
    }
