Parsing an image with JAI
<p>I use JAI, because I want to work with a tif. I read the image into a PlanarImage</p>

<p>The whole problem:
Now I have to do some calculations on this image. First I have to read the RGB values, then do some calculations on blocks with 16x16 pixels.</p>

<p>What's the best way to do this?</p>

<p>Does anyone have an idea?</p>
