Example

Here is an example that shows how to open Nikon NEF-file, get RAW-image from NEF-file and save image to a PNG-file:

VB.NET

''' <summary>
''' Opens Nikon NEF-file, gets RAW-image from NEF-file and saves image to a PNG-file.
''' </summary>
''' <param name="crwFilename">The name of NEF-file.</param>
Public Sub GetAndSaveNefRawImage(crwFilename As String)
    ' open NEF-file stream
    Using fs As New System.IO.FileStream(crwFilename, System.IO.FileMode.Open, System.IO.FileAccess.Read)
        ' open NEF-file
        Dim rawImageFile As New Vintasoft.Imaging.Codecs.ImageFiles.Raw.RawImageFile(fs)
        ' get NEF-page
        Dim nefPage As Vintasoft.Imaging.Codecs.ImageFiles.Raw.NefPage = TryCast(rawImageFile.Page, Vintasoft.Imaging.Codecs.ImageFiles.Raw.NefPage)
        ' if NEF-page is found in RAW-file
        If nefPage IsNot Nothing Then
            ' get RAW-image as 48-bpp RGB image
            Using rawImage As Vintasoft.Imaging.VintasoftImage = nefPage.GetImage()
                ' save 48-bpp RGB image to a PNG file
                rawImage.Save(crwFilename & ".png")
            End Using
        End If
    End Using
End Sub

/// <summary>
/// Opens Nikon NEF-file, gets RAW-image from NEF-file and saves image to a PNG-file.
/// </summary>
/// <param name="crwFilename">The name of NEF-file.</param>
public void GetAndSaveNefRawImage(string crwFilename)
{
    // open NEF-file stream
    using (System.IO.FileStream fs = new System.IO.FileStream(crwFilename, System.IO.FileMode.Open, System.IO.FileAccess.Read))
    {
        // open NEF-file
        Vintasoft.Imaging.Codecs.ImageFiles.Raw.RawImageFile rawImageFile =
            new Vintasoft.Imaging.Codecs.ImageFiles.Raw.RawImageFile(fs);
        // get NEF-page
        Vintasoft.Imaging.Codecs.ImageFiles.Raw.NefPage nefPage =
            rawImageFile.Page as Vintasoft.Imaging.Codecs.ImageFiles.Raw.NefPage;
        // if NEF-page is found in RAW-file
        if (nefPage != null)
        {
            // get RAW-image as 48-bpp RGB image
            using (Vintasoft.Imaging.VintasoftImage rawImage = nefPage.GetImage())
            {
                // save 48-bpp RGB image to a PNG file
                rawImage.Save(crwFilename + ".png");
            }
        }
    }
}
