8 If you want to make ALL white pixels transparent, it would be easier
9 to use imagemagick
10
11 convert <inputfilename> -transparent <color> <outputfilename>
12
13 <color> can be specified by name (white) or rgb values. cf.
14 http://www.imagemagick.org/script/convert.php
15
16 And since the file is created in pbrush, there's a slight possibility
17 the file didn't support transparency to start with. You can set the
18 outputfilename to foo.png and let convert change to format also...
