Thanks for your reply.

This is to inform you that I am using :
Language:- Java 1.8
Aspose slide for java: 19.4 version
IDE: NetBeans
Operating System: Ubuntu

Code:-

String dataDir = "/home/Ubuntu/Downloads/Slides/Test/";

//Instantiate a Presentation class that represents the PPTX file
Presentation pres = new Presentation(dataDir + "Presentation1.pptx");
		 
//Access the first slide
ISlide sld = pres.getSlides().get_Item(0);
		 
//Create a full scale image
BufferedImage image = sld.getThumbnail(1f, 1f);
		 
//Save the image to disk in JPEG format
ImageIO.write(image,"jpeg",new File(dataDir + "/img/" + "theme 1 img 4.jpg"));

Thanks,
Saquib Shaikh.
