aryBound

Enquire the pixel-index bounds of an array

This function returns the lower and upper pixel-index bounds of each dimension of an array, together with the total number of dimensions.

void aryBound( Ary

*

ary, int ndimx, hdsdim

*

lbnd, hdsdim

*

ubnd, int

*

ndim, int

status )

If the array has fewer than " ndimx" dimensions, then any remaining elements of the " lbnd" and " ubnd" arguments 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" sets of bounds will be returned, and an error will result if the size of any of the remaining dimensions exceeds 1.
The symbolic constant ARY__MXDIM may be used to declare the size of the " lbnd" and " ubnd" arguments so that they will be able to hold the maximum number of array bounds that this routine can return. This constant is defined in the header file " ary.h" .

Array identifier.

Maximum number of pixel-index bounds to return (i.e. the declared size of the " lbnd" and " ubnd" arguments).

Returned holding the lower pixel-index bounds for each dimension.

Returned holding the upper pixel-index bounds for each dimension.

Returned holding the total number of array dimensions.
