What you say is true, but it seems unlikely to me that an imaging
operation would be coded with fixed dimensions. More likely that each
operation is a function taking image arguments with specified
dimensions. In the 2d case
fun(pixel **image, ...)
the pixels are accessed as image[y][x], and in the 1d case
fun(pixel *image, int w, ...)
one would have to write image[y * w + x].

There seems to be some confusion.
In C, the following two arrays are interchangeable:
int twoDArray[100][500];
int oneDArray[100 * 500];
Both occupy the same amount of memory. They can be cast back and
forth harmlessly. Both are of the following assignments are legal
and meaningful:
int *array = twoDArray;
int *array = oneDArray;
Both styles of array decalartion are usable with -
initWithBitmapDataPlanes:pixelsWide:pixelsHigh:bitsPerSample:samplesPerPixel:hasAlpha:isPlanar:colorSpaceName:bitmapFormat:bytesPerRow:bitsPerPixel
and with openGL.
