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.
