Take pixels values from pic with specifiec order

[Leite33]

Hi
one good question.
I have one pic 3X3. Width=3 Height=3

let say with values:

0 1 2
3 4 5
6 7 8
With 2 for (1 for width and 1 for height)i was able to take that values and save to one dimension array with that way:
PixelValues=0,3,6,1,4,7,2,5,8
My question:
Is possible to take that values with that order: 4,5,8,7,6,3,0,1,2.
Is possible to do that with for?? Or i need something else???
The method i use is PixelValues=Image1->Canvas->Pixels[i][j];
