Draw in a lcd with a Wacom?

HI List ,

I have a big problem and I don't find any solutions ..
I would like to draw in a lcd like you draw when you use the mouse inside but with a wacom .

I tried to use the coordinates of the wacom (with the wacom~ object ) and put "setpixel" before , but the problem it's I work just pixel by pixel ...

I would like give location from my wacom to the lcd (coordinates like the first output of lcd object reports) and use also the pensize function to have a more or less bigger pen size

someone have an a idea ? it's a little bit urgent ...

thanks by advance.
