<li>Create directory <b>/sdcard/Download/volumes/</b></li>

".prop" files are simple jave properties files which consist

<h3>Opacity table</h3>
|
|
opacity tabls consisit of nested arrays of shorts.
|
|
The first being intensity the second being opacity on a 0-255 scale.
|
|
The values for each pixel in the volume are interpolated
|
|
<p></p>
|
|
<h3>Color table</h3>
|
|
The color table
|
|
The values are linearly interpolated from one value to the next
|
