Hello people and thank you for your suport

To Bill : 
> Does he need to do cairo_flush(cr) before using the pixels?
 I cannot find this function

> You did not set the current point before drawing the text, so I think it

Well I tried to change that also, without succes; I must say that I can see the surface at the place I want it to be, but it is just a white rectangle with nothing written on it...

> image?

I did; no change untill now.

To Henry :

>You use RGBA as format in glTexImage2D(), make sure your image data is RGBA format.

I don't know how to check that in Cairo;

To everyone : Thank you again
