title: How to create a big image file from many tiles in java?
body: <p>My program produces 10 x 10 tiles images of 3000x3000 pixel, one by one (currently saved to 100 files named <code>image_x_y.jpg</code>)</p>
  
  <p>I want to assemble these 100 images into one big image, without loading everything in memory. My goal is to create one big image file, of 30'000 * 30'000 pixels.</p>
  
  <p>I'm looking for a way to do this <em>without</em> using JAI (which cannot be installed from public maven repositories, I don't understand why)</p>
  
  <p>Is there a way to do this with pure java2D ? Or does another library exist, able to handle this ?</p>
  
  <p>My original idea was to create a very big buffered image, from a DataBuffer backed to a file on the disk. But i'm not sure that this is possible. Did anybody ever do this ?</p>
