    How to acquire 48-bit color images from scanner?
    In This Topic

    16-bit gray images and 48-bit color images can be acquired from the device only in Memory transfer mode.


    Example: Here is an example that shows how to acquire 48-bit color images from the device.

    ''' <summary>
    ''' Acquire 48-bpp color images.
    ''' </summary>
    Public Sub Acquire48BppColorImages(ByVal device As Vintasoft.Twain.Device)
        ' use the Memory transfer mode
        device.TransferMode = Vintasoft.Twain.TransferMode.Memory
        ' disable UI
        device.ShowUI = False
    
        ' open the device
        device.Open()
        ' specify that color images must be acquired
        device.PixelType = Vintasoft.Twain.PixelType.RGB
        ' specify the bit depth for acquired images (16 - for Epson scanners, 48 - for Canon scanners)
        device.BitDepth = 16
    
        ' acquire images asynchronously
        device.Acquire()
    End Sub
                  
    
    /// <summary>
    /// Acquire 48-bpp color images.
    /// </summary>
    public void Acquire48BppColorImages(Vintasoft.Twain.Device device)
    {
        // use the Memory transfer mode
        device.TransferMode = Vintasoft.Twain.TransferMode.Memory;
        // disable UI
        device.ShowUI = false;
    
        // open the device
        device.Open();
        // specify that color images must be acquired
        device.PixelType = Vintasoft.Twain.PixelType.RGB;
        // specify the bit depth for acquired images (16 - for Epson scanners, 48 - for Canon scanners)
        device.BitDepth = 16;
    
        // acquire images asynchronously
        device.Acquire();
    }
