I've added the last line of the snippet I previously posted,but after
about four 
iterations (during which however the Raster remains black), the program
receives a
 "Segmentation fault 0x61053592 in _size_of_stack__reserve()" when
[raster setWidth: [self getWidth] Height: [self getHeight]] is invoked.
Another thing I've noticed is that the raster's width is greater that
its height even if I set
the same value both for width and height.
