바운더리와 관련된 Listener (확장 가능한 벡터 그래픽의 "노드"라고 생각 함)가있는 Map을 만들기위한 .svg 파일이 있습니다. 그러나 JPanel 위에 BufferedImage로이 파일을 추가하려고합니다. (저는 스윙 구성 요소에 대한 초보자입니다. 더 좋은 아이디어가 있으면 공유하십시오.) 또한, 나는 Batik 라이브러리를 사용하고 대한 몇 가지 정보를 읽고 난 BufferedImage로서이 .svg 파일을 얻기 위해이 코드 샘플을 사용java.lang.NoClassDefFoundError BufferedImage로 svg 파일을 읽는 중

내가 BufferedImage를 사용하려고 곳이 내 GUI 구성 요소를 사용하는 클래스와 부분이다
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class JRisk {
private JFrame mainMap;
public JRisk() throws IOException{
initComponents();
}
private void initComponents() throws IOException{
mainMap = new JFrame();
mainMap.setResizable(false);
JPanel mainPanel = new JPanel();
File riskMap = new File("src\\src\\risk.svg");
BufferedImage bufImage = SVGRasterizer.rasterize(riskMap);
mainMap.setIconImage(bufImage);
mainMap.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
mainMap.add(mainPanel);
mainMap.pack();
mainMap.setVisible(true);
}
}
