Ok, now I you are on the best way to find out something I did not tell
many people so far, I am going to blab out how the generic tools in Jave
1.0 work. Well, I will not tell you how exactly it works but you should
be able to see the idea when doing the following:

  Start Jave, chose one of the (green) generic tools. Chose "Thick1" as
style (should be easiest with this one, though it works with others).
Begin painting, but keep the mouse pressed so you can see the (blue)
preview. Now press and hold the Ctrl-Key while still holdinging the
mouse button.

Now you should see how it works. :-)
In Jave 1.0 there are only two generic conversion algorithms. If you
still want to find out more about them, have a look at
jave/code/convert.txt and /jave/code/convert_thick.txt. But I am not
going to tell you more about this all.

In Jave 1.1 there will be one additional style for generic tools: "Dot"
                                       .........
           ..'''''''..           ..''''         ''''..
        .''           ''.      .'                     '.
      .'                 '.    :                       :
     :                     :    '..                 ..'
    :                       :      ''''.........''''
   :                         :
   :                         :        .'''''.
   '    ......               :      .'       '.
     .''      ''..          .'     :           :.
    .'            :        .'    .'             '':
   .'              :      .'    :
  .'                '.   '   .''
                      '''''''

I have also tested the style with JFL7."_ etc., but it does not work
well with those tools:

                                  ,__
     ________.                 ,_"'  "".
   _"        `_              ,/'       ".
  /            ".           /'          ).
 ,'             `"_       _"             `_
                   "____""                 "_ ,_
                                             "'
So you can see: I have tried those algorithms on tools - in fact you
already have used them without knowing (if you have worked with Jave)
:-)

But I have not integrated them into the image2ascii converter yet :-/
There are so many things to be done... :(
Be patient, Jave1.1 will be released soon :)
