    Example
    Removing lines from a black and white tiff image.
    using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    {
        // LoadInMemory parameter is set to true in order to be able to update the input file.
        int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.tif", true);
     
        // Remove vertical and horizontal lines using default parameters.
        gdpictureImaging.RemoveLines(imageID, LineRemoveOrientation.Horizontal | LineRemoveOrientation.Vertical);
        gdpictureImaging.SaveAsTIFF(imageID, "image.tif", TiffCompression.TiffCompressionCCITT4);
        gdpictureImaging.ReleaseGdPictureImage(imageID);
