Example

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

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing;

{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string flipExamplesImage1 = Path.Combine(LEAD_VARS.ImagesDir, "Image1_horizontal.bmp"); 
	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) 
	FlipCommand cmd = new FlipCommand(); 
	cmd.Horizontal = true; 
	cmd.Run(image); 
 
	// Save the image to disk 
	codecs.Save( 
	   image,
