NAME
     btree - display an image using a binary tree ordering.

SYNOPSIS
     btree inimage [depth]

DESCRIPTION
     btree displays an image using a progressive technique.  First it is drawn
     as a 2 by 2 array of rectangles, then rectangles are added to make it a 4
     by 4 array.  The resolution is increased in this way to the default level
     which is depth 8.  To manually set the level of resolution to be other
     than 8, specify depth as some integer value.
