	RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
	byte[] row1 = new byte[image.BytesPerLine]; 
	byte[] row2 = new byte[image.BytesPerLine]; 
 
	image.Access(); 
	for (int y = 0; y < image.Height / 2; y++) 
	{ 
		image.GetRow(y, row1, 0, row1.Length); 
		image.GetRow(image.Height - y - 1, row2, 0, row2.Length); 
 
		image.SetRow(y, row2, 0, row2.Length); 
		image.SetRow(image.Height - y - 1, row1, 0, row1.Length); 
	} 
	image.Release(); 
 
	codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1_getrow.BMP"), RasterImageFormat.Bmp, 0); 
 
	image.Dispose(); 
	codecs.Dispose(); 
}
