This function returns the size in pixels of each dimension of an array, together with the total number of dimensions (the size of a dimension is the difference between that dimension’ s upper and lower pixel-index bounds $+$ 1).

void aryDim( Ary $\ast$ary, int ndimx, hdsdim $\ast$dim, int $\ast$ndim, int $\ast$status )

• If the array has fewer than " ndimx" dimensions, then any remaining elements of the " dim" argument will be filled with 1’ s.

• If the array has more than " ndimx" dimensions, then the " ndim" argument will return the actual number of dimensions. In this case only the first " ndimx" dimension sizes will be returned, and an error will result if the size of any of the excluded dimensions exceeds 1.

• The symbolic constant ARY__MXDIM may be used to declare the size of the " dim" argument so that it will be able to hold the maximum number of array dimension sizes that this routine can return. This constant is defined in the header file ary.h.
