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.

As well as reference the Library Path and the Platform.loadLibrary() for any libraries that need to be accessed

Code:

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

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.CODECS);
	        
	        //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");
	        }
	    	
		}catch (Exception ex) {
			ex.printStackTrace();
		}

Once that has been done you can include the calls to reference the file that is being converted and saved out to another file format
The LEADTOOLS RasterCodecs.save() method is a very simple yet very powerful method as it will allow you to save out the file, but also simultaneously convert it to another file format.

Code:

try {
			
			String srcFileName = "C:\\Users\\cthompson\\Desktop\\Leadtools.pdf";
			String dstFileName = "C:\\Users\\cthompson\\Desktop\\Leadtools_test.tif";
			
			RasterCodecs codecs = new RasterCodecs();
			RasterImage image = codecs.load(srcFileName);
			
			codecs.save(image, dstFileName, RasterImageFormat.TIF, 0);
			
			codecs.dispose();
			image.dispose();
			
		}catch (Exception ex){
			ex.printStackTrace();
		}
