That's not possible. In detail: this is for an OpenGL-Method, and the array
can be e.g.
height x width x 3 - byte array; e.g. RGB
height x width x 1 - float array; e.g. alpha
height x width x 4 - float array; e.g. RGBA
and so on ....
Via additional call parameters OpenGL is informed about the array structure.

In the original programm it is a field in my test program a local variable at
the moment, but it was there a field too.
