title: Java image Tile Processing, byte binary image
body: <p>I'm processing the large <strong>tiff</strong> image in <strong>java</strong>. My object is just read pixel value, calculate the ink area. </p>
  
  <p>The tiff image is black &amp; white image, byte binary image.
  So I think pixel values are either 0 or 1 that white is 1, black is 0. 
  But some sample files are correct. some files are not.
  In some files 0 is black, 1 is white.</p>
  
  <p>Is it possible?</p>
  
  <p>The common point is 0:black, 1:white file is processed in windows photo editor.
  0:white, 1:black is processed in EskoArtwork imaging engine.</p>
  
  <p>Can the definition of an image pixel change depending on the engine?</p>
