Like with all LEADTOOLS applications you will first need to provide a valid License and Key file that needs to be passed through the RasterSupport.setLicense() method.

Below is a simple Rotate command that can be implemented with the LEADTOOLS SDK in Java
In some cases the rotation of a document page can work as a security method.

Code:

import leadtools.*;
import leadtools.codecs.*;
import leadtools.imageprocessing.*;

public class simpleRotate {
	public static void main(String[] args) {
		
		try{
			
			Platform.setLibPath("C:\\LEADTOOLS 20\\Bin\\CDLL\\x64");
			
			Platform.loadLibrary(LTLibrary.LEADTOOLS);
			Platform.loadLibrary(LTLibrary.DOCUMENT_WRITER);
	         
	        //String licensePath = "C:\\LEADTOOLS 20\\Support\\Common\\License\\LEADTOOLS.LIC";
			String licensePath = "ENTER FILE PATH TO LICENSE HERE";
			String developerKey = "ENTER STRING FROM KEY HERE";
			
			// Set your license
	        RasterSupport.setLicense(licensePath, developerKey);

	        if (RasterSupport.getKernelExpired()) {
	            System.out.println("License NOT Set Successfully");
	        } else {
	            System.out.println("License Set Successfully");
	        }
	    	
	        String fileName = "C:\\Users\\cthompson\\Desktop\\Leadtools.tif";
			String outFileName = "C:\\Users\\cthompson\\Desktop\\AfterRotation_Tif_Test.tif";
			
			RasterCodecs codecs = new RasterCodecs();
			
			RasterImage image = codecs.load(fileName, 0, CodecsLoadByteOrder.BGR_OR_GRAY, 1, -1);
			
			RotateCommand command = new RotateCommand();
			command.setAngle(90 * 100);
			command.run(image);
			
			codecs.save(image, outFileName, RasterImageFormat.TIF, 0);
			
			image.dispose();
			codecs.dispose();
	        
		}catch (Exception ex) {
			ex.printStackTrace();
		}
	}
}
