title: Java Graphics Font - How to make sure the characters lie in particular area?
body: <p>I have an Image. On the bottom portion of the image, I would like to create a colored strip say, of height 100. I am already done with creating the strip and I can basically write strings in that portion (e.g. copyright of the image etc). The following is my method.</p>
  
  <pre><code>public static BufferedImage captionMyImage(BufferedImage sourceImage) {
  
      int height=sourceImage.getHeight();
      int width=sourceImage.getWidth();
  
      System.out.println("Image Height: "+height);
      System.out.println("Image Width: "+width);
  
      int min=20; //fifty pixels
      int newHeight=(int) (0.1*height&gt;min ? 1.1*height : height+min);
      int difference=newHeight-height;
      System.out.println("new height:"+newHeight);
      System.out.println("Difference:"+difference);
      BufferedImage bgImage=new BufferedImage(width,newHeight,BufferedImage.TYPE_INT_RGB);
  
  
  
      /**Create a Graphics  from the background image**/
      Graphics2D g = bgImage.createGraphics();
  
      //g.drawRect(0, 0, width, ((int)0.1*height&gt;min) ? (int)1.1*height : height+min);
      g.setColor(Color.RED);
      g.fillRect(0, 0, bgImage.getWidth(), bgImage.getHeight());
      g.setColor(Color.YELLOW);
  
  
  
      /**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(sourceImage, 0, 0, null);
  
      int strX=sourceImage.getWidth()/2;
      int strY=sourceImage.getHeight()+difference/2;
      System.out.println("X: "+strX);
      System.out.println("Y: "+strY);
      g.setFont(new Font(g.getFont().getName(),Font.PLAIN,20));
      g.drawString("(c)www.sanjaal.com",strX ,strY);
  
      g.dispose();
  
      return bgImage;
  }
  </code></pre>
  
  <p>I know the way I have calculated the values for x and y for drawString() method is just a simple one and has problem that the text goes outside the boundary sometimes (depending on image size and text length)</p>
  
  <p>I would like to make sure that the text in the image on the bottom strip that I have defined always aligns to the right portion (boundary) of the image, but does not go out of boundary. How can I achieve that? Remember the text length can be dynamic.</p>
  
  <p>Would the java Graphics experts out there share your ideas on how this can be achieved?</p>
