im new at java gui, any suggestion to make those image to have smoother edges…
i read alike problems but I couldnt grasp how can I correlate it to my situation…

images has not so good edges

ps. the custom panel class ask for Color color, int x position, int y position, int layoutManager, and ImageIcon…

for (int i = 0; i < 8; i++){
                    playlist[i] = new Panel(new Color(110, 110, 110, 50), 0, 0, null, data.recently_clicked_non_artist.get(i).getImageAsRecentlyPlayed()){
                        @Override
                        protected void paintComponent(Graphics g){
                            super.paintComponent(g);
                            Dimension arcs = new Dimension(arc, arc);
                            int width = getWidth();
                            int height = getHeight();
                            Graphics2D g2d = (Graphics2D)g;
                            g2d.setClip(0, 0, getWidth(), getHeight());
                            g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
            
                            //Draws the rounded opaque panel with borders
                            g2d.setColor(getBackground());
                            g2d.fillRoundRect(0, 0, width-1, height-1, arcs.width, arcs.height);
                            g2d.setColor(Color.RED);
                            // g2d.fillRoundRect(0, 0, 50, height-1, arcs.width, arcs.height);
                            g2d.setClip(new RoundRectangle2D.Float(0, 0, 50, getHeight(), arcs.width, arcs.height));
                            g2d.drawImage(getImageIcon().getImage(), 0, 0, 50, getHeight(), null);
                            
                        }
                    };
                    playlist[i].setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
                    subTopPanel.add(playlist[i]);

I tried putting g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); but it doesnt seem to help me…
