Re: How to Join two images

Question

Do you want to side by side the images so one is on the left and the other on the right? If so just make them the appropriate size and copy them to the correct locations.
If you want to overlay on onto the other then xor them.

Answer 1

i have tried following code but it gives me image of 2 strips
public static void joinImage()throws Exception{
          //loads two images with ImageIO
          //for testing purpose both header and content image are same
          BufferedImage imageHeader=ImageIO.read(new File("/home/g.pol/images/DSC04249.JPG"));
          System.out.println(""+imageHeader.getHeight()+" "+imageHeader.getWidth());
     BufferedImage imageContent=ImageIO.read(new File("/home/g.pol/images/DSC04249.JPG"));
     //create new BufferedImage instance of same width and height as that of merging images
     BufferedImage resultantImage=new BufferedImage(imageHeader.getWidth(),imageHeader.getHeight()*2,BufferedImage.TYPE_INT_ARGB);
     //get graphichs of resultant image
     Graphics resultantGraphics=resultantImage.getGraphics();
     //draw image on graphics with width is same as that of test images but height 1/2 of test image
     resultantGraphics.drawImage(imageHeader,0,0,null);
     resultantGraphics.drawImage(imageContent,0,50,null);
     ImageIO.write(resultantImage,"jpg",new File("/home/g.pol/images/result.JPG"));
     System.out.println("success");
     }
