Following the association list record is the plane size record:
typedef struct { llvs_integer datatype_again; /* plane data type (redundant) */ llvs_integer row_dimension; /* plane row dimension */ llvs_integer col_dimension; /* plane col dimension */ } LLVS_PLANE_SIZE_HEADER;
This record describes the size of the plane in elements, giving the plane dimensions. The plane data is actually just a two-dimensional array of numerical values, each element of which represents a single picture element (called a ``pixel'').
