2 개의 이미지 중첩이 제대로 작동하지 않습니다.

Question

JPEG 이미지를 통해 두 이미지의 PNG/TIFF 파일을 병합하려고합니다. 다음 코드

try { 
         image = ImageIO.read(new File("C:\\Users\\user\\Desktop\\test\\a.jpg")); 
        } catch (IOException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 
        BufferedImage overlay = null; 
        try { 
         overlay = ImageIO.read(new File("C:\\Users\\user\\Desktop\\test\\b.png")); 
        } catch (IOException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 

        // create the new image, canvas size is the max. of both image sizes 
        int w = Math.max(image.getWidth(), overlay.getWidth()); 
        int h = Math.max(image.getHeight(), overlay.getHeight()); 
        BufferedImage combined = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB); 

        // paint both images, preserving the alpha channels 
        Graphics2D g = combined.createGraphics(); 
        /**Set Antialias Rendering**/ 
        g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, 
          RenderingHints.VALUE_ANTIALIAS_ON); 
        /** 
         * Draw background image at location (0,0) 
         * You can change the (x,y) value as required 
         */ 
        g.drawImage(image, 0, 0, null); 

        /** 
         * Draw foreground image at location (0,0) 
         * Change (x,y) value as required. 
         */ 
        g.drawImage(overlay, 0, 0, null); 

        g.dispose(); 

        // Save as new image 
        try { 
         ImageIO.write(combined, "JPG", new File("C:\\Users\\user\\Desktop\\test\\c.jpg")); 
        } catch (IOException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 

하지만, 내가 원하는 내용에 따라되지 형성되어 다음 최종 이미지를 사용하고 있습니다. 명확성을 위해 첨부 된 이미지를 참조하십시오. 당신이 아래에있는 이미지를 볼 수 있도록
