Form has some class side methods to create Forms from arrays, too.

Thanks you for your answer, however there is something I missed here.
I've tried following code
| w h bytes form |
w := 200.
h := 200.
bytes := ((1 to: w*h) collect: [:i | 255 ]) asByteArray.
(1 to: w) do: [ :x |
(1 to: h) do: [ :y |
x = y ifTrue: [ bytes at: (w*(y - 1) + x) put: 0 ]
