VB.NET


' open the original image
Using originalImage As New Vintasoft.Imaging.VintasoftImage("c:\original-image.tif")
    ' open the overlay image
    Using overlayImage As New Vintasoft.Imaging.VintasoftImage("c:\overlay-image.tif")
        Dim g As System.Drawing.Graphics = Vintasoft.Imaging.VintasoftImageGdiExtensions.OpenGraphics(originalImage)
        ' draw the overlay image on the original image
        Vintasoft.Imaging.VintasoftImageGdiExtensions.Draw(overlayImage, g, New System.Drawing.Rectangle(300, 400, 500, 600), New System.Drawing.Rectangle(1000, 200, 1000, 700))
    End Using

    ' close Graphics of the overlay image
    Vintasoft.Imaging.VintasoftImageGdiExtensions.CloseGraphics(originalImage)

    ' save original image
    originalImage.Save("c:\processed-image.tif")
End Using


// open the original image
using (Vintasoft.Imaging.VintasoftImage originalImage =
    new Vintasoft.Imaging.VintasoftImage(@"c:\original-image.tif"))
{
    // open the overlay image
    using (Vintasoft.Imaging.VintasoftImage overlayImage =
        new Vintasoft.Imaging.VintasoftImage(@"c:\overlay-image.tif"))
    {
        System.Drawing.Graphics g = Vintasoft.Imaging.VintasoftImageGdiExtensions.OpenGraphics(originalImage);
        // draw the overlay image on the original image
        Vintasoft.Imaging.VintasoftImageGdiExtensions.Draw(overlayImage, g,
                            new System.Drawing.Rectangle(300, 400, 500, 600),
                            new System.Drawing.Rectangle(1000, 200, 1000, 700));
    }

    // close Graphics of the overlay image
    Vintasoft.Imaging.VintasoftImageGdiExtensions.CloseGraphics(originalImage);

    // save original image
    originalImage.Save(@"c:\processed-image.tif");
}
