title: How to convert TIFF to JPEG/PNG in java
body: <p>recently i'm facing problem when try to display an image file. Unfortunately, the image format is TIFF format which not supported by major web browser (as i know only Safari support this format). Due to certain constraint, i have to convert this format to others format that supported by major browser. However, it bring a lots of problem for me when i try to converting the format.</p>
  
  <p>I had search through the web and although there been posted similar issue in this link <a href="https://stackoverflow.com/questions/2291358/how-do-i-convert-a-tif-to-png-in-java">How do I convert a TIF to PNG in Java?</a>" but i can't have the result as it proposed..</p>
  
  <p>Therefore i raise this Question again to wish that can have better explanation and guideline from you all..</p>
  
  <p>There were few issue i'm faced during go through with the solution that proposed:</p>
  
  <p>1) According to the answer that proposed by <strong>Jonathan Feinberg</strong>, it need to install JAI and JAI/ImageIO. 
  However, after i installed both of them i still couldn't import the file in Netbean 7.2. NetBean 7.2 remain propose import default imageIO library.</p>
  
  <p>2) when i'm using default ImageIO library Read method, it will return NULL value and i cannot continue to proceed.</p>
  
  <p>3) I also tried others method such as convert TIFF file to BIN File by using BufferedOutputStream method but the result file is greater than 11 MB which is too large to load and end up loading failed.</p>
  
  <pre><code> if (this.selectedDO != null) {
          String tempDO = this.selectedDO.DONo;
          String inPath = "J:\\" + tempDO + ".TIF";
          String otPath = "J:\\" + tempDO + ".bin";
  
          File opFile = new File(otPath);
  
          File inFile = new File(inPath);
  
          BufferedInputStream input = null;
          BufferedOutputStream output = null;
          try {
              input = new BufferedInputStream(new FileInputStream(inPath), DEFAULT_BUFFER_SIZE);
              output = new BufferedOutputStream(new FileOutputStream(otPath), DEFAULT_BUFFER_SIZE);
  
              byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
              int length;
              while ((length = input.read(buffer)) &gt; 0) {
                  output.write(buffer, 0, length);
              }
  
          } finally {
              try {
                  output.flush();
                  output.close();
                  input.close();
              } catch (IOException e) {
                  e.printStackTrace();
              }
          }
  </code></pre>
  
  <p>Hence, hope that can get help and advise from you all so that i can convert TIFF format to other format such as JPEG/PNG.</p>
