Example

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

VB.NET


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


/// <summary>

public void GetAndSaveCrwRawImage(string crwFilename)
{
    // open CRW-file stream
    using (System.IO.FileStream fs = new System.IO.FileStream(crwFilename, System.IO.FileMode.Open, System.IO.FileAccess.Read))
    {
        // open CRW-file
        Vintasoft.Imaging.Codecs.ImageFiles.Raw.RawImageFile rawImageFile =
            new Vintasoft.Imaging.Codecs.ImageFiles.Raw.RawImageFile(fs);
        // get CRW-page
        Vintasoft.Imaging.Codecs.ImageFiles.Raw.CrwPage crwPage =

        // if CRW-page is found in RAW-file
        if (crwPage != null)
        {
            // get RAW-image as 48-bpp RGB image
            using (Vintasoft.Imaging.VintasoftImage rawImage = crwPage.GetImage())
            {
                // save 48-bpp RGB image to a PNG file
                rawImage.Save(crwFilename + ".png");
            }
        }
    }
}
