I am using below library to convert JP2 image to JPG.

 <dependency>
			<groupId>com.github.jai-imageio</groupId>
			<artifactId>jai-imageio-jpeg2000</artifactId>
			<version>1.3.0</version>
		</dependency>

The image after conversion introduce multiple black spots. When i use online image converter (https://www.freefileconvert.com/)then it works fine.

Below is the output jpg, from code i used.
enter image description here

You can observe black spots around the image. I am not able to attached source JP2 file here.

Code i used is as below:

public class CreateImageFileFromGraphicsObject

public static void main(String args) throws IOException 
 int width = 250;
 int height = 250;
 File foundFile = new File("C:\Users\krishnam\Documents\PDFDocs\Arun\arun_Text-2.jp2");
 BufferedImage fb = ImageIO.read(foundFile);

 // Constructs a BufferedImage of one of the predefined image types.
 BufferedImage bufferedImage = new BufferedImage(fb.getWidth(), fb.getHeight(), BufferedImage.TYPE_INT_RGB);

 // Create graphics which can be used to draw into the buffered image
 bufferedImage.createGraphics().drawImage(fb,0,0,Color.WHITE,null);
 Graphics2D g2d = bufferedImage.createGraphics();
 g2d.setBackground(Color.white);
 // create a string with yellow
 g2d.setColor(Color.yellow);
 g2d.drawString("Java Code", 50, 120);
 g2d.dispose();
 // Save as PNG
 File file = new File("C:\Users\krishnam\Documents\PDFDocs\Arun\myimage.png");
 ImageIO.write(bufferedImage, "png", file);

 // Save as JPEG
 file = new File("C:\Users\krishnam\Documents\PDFDocs\Arun\myimage.jpg");
 ImageIO.write(bufferedImage, "jpg", file);
 System.out.println("Completed!!!");

Please suggest how i can upload JP2 file.

Note: I also used an application to convert JP2 to JPG which works fine.

I also downloaded few sample images and tried converting with above code, it works perfectly.
