Pixels are laid out in a one-dimensional array, where the first (size.width * 4) bytes are the first (top-most) row of pixels in the image such that the first pixel is the top left one, the next (size.width * 4 bytes) are the second row of pixels, etc, up to the number of rows indicated by size.height. The total length of the pixels array must therefore be (size.width*4) * size.height."}
