Finally I came on&nbsp; a good solution: a double buffering,...<br>
the trick is to keep the same draw on an addtional bitmap<br>
and at the end of the plot to derive this buffer on the screen.<br>
<br>
al least it is a temporal solution...<br>
<br>
if anybody knows a better solution<br>
we will listen it with attention.<br>

<pre>"void vsync( )" is a function in Allegro library
to write on the graphics card during the retrace interval
of the electron beam in a monitor ....

but how can I do the same with a Liquid Crystal Screen (LCD)??...
the system refreshes automatically the screen and the graphics is lost....

why??...how can I avoid of losing the images in a LCD  ??.


any help is strongly appreciated.
