How are the pixels placed in an int[] array of pixels when getting pixels from a Android Bitmap?

I really need to know some detail about bitmap.getPixels(...), that the documentation does not say. I want to know how are the pixels displayed in the int[] array. Is it row after row or column after column?

To be more specifi:

imagine image: [0,0][0,1][0,2][0,3]
               [1,0][1,1][1,2][1,3]
array looks like this?: [0,0],[0,1],[0,2],[0,3],[1,0],[1,1],[1,2],[1,3]
or it looks like this?: [0,0],[1,0],[0,1],[1,1],[0,2],[1,2]...

Thank you!

The third parameter of getPixels function (int stride), is necessary to say at the function how many pixels there are for each row. So the function know that after X pixels have to skip at new row.

Here you can find the documentation!
