Images and data structures

The ARGetImage function returns image contents in an ARImageDataStruct:


typedef struct ARImageDataStruct
{
   unsigned int      numItems;      /* length in bytes     */
   unsigned char     *bytes;        /* not NULL terminated */
} ARImageDataStruct;
} ARImageDataStruct;
typedef struct ARImageDataList
{
   unsigned int      numItems;
   ARImageDataStruct *imageList;
   ARImageDataStruct *imageList;
} ARImageDataList;    /* list of 0 or more image data structs */
