Example

This example will load an image and then flip it before saving it back to disk.

Java

	string flipExamplesImage2 = Path.Combine(LEAD_VARS.ImagesDir, "Image1_horizontal.bmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
 
	// Flip the image horizontally (reverse)
