Hi everybody,
I am creating Text2D shapes with labels for some points. When I create
them near 0 with say a font size around up to 100 everything is okay.
In my real application my points are somewhere around x 3500000 and z
-5000000. That is why I want to go back and make the font size bigger, so
that I still can see my labels. But then I can only see the rectangular
area of the texture, which is no longer transparent.
You can verify this with the attached example program. Changing the font
size from 660 to 560 and the text will show.
I tested the
//text2D.setRectangleScaleFactor(2);
//text2D.setString("new 2D Text");
methods, but it did not understand the effects.
With enlarging the font size I additionally get often an out of memory
error.
Thanks for your help in advance
Desiree
