tunately this causes bitblt to have a couple of strange restrictions.
Wraparound does not work correctly if from-raster is an indirect array with
an index offset. bitblt signals an error if the widths of from-raster and
to-raster are not both integral multiples of the machine word length. For
sys:art-lb arrays, width must be a multiple of 32., for sys:art-2b arrays it
must be a multiple of 16., and so on.
bit-eqv first second &optional third Function
Performs logical exclusive nor operations on bit arrays. The arguments
must be bit arrays of the same rank and dimensions. A new array is
created to contain the result if the third argument is nil or omitted. If the
third argument is t, the first array is used to hold the result.
bit-ior first second &optional third Function
Performs logical inclusive or operations on bit arrays. The arguments must
be bit arrays of the same rank and dimensions. A new array is created to
contain the result if the third argument is nil or omitted. If the third argument
is t, the first array is used to hold the result.
bit-nand first second &optional third Function
Performs logical not and operations on bit arrays. The arguments must be
bit arrays of the same rank and dimensions. A new array is created to
contain the result if the third argument is nil or omitted. If the third argument
is t, the first array is used to hold the result.
bit-nor first second &optional third Function
Performs logical not or operations on bit arrays. The arguments must be
bit arrays of the same rank and dimensions. A new array is created to
contain the result if the third argument is nil or omitted. If the third argument
is t, the first array is used to hold the result.
bit-not source &optional destination Function
source must be a bit-array. bit-not returns a bit-array of the same rank
and dimensions that contains a copy of the argument with all the bits inverted.
If destination is nil or omitted, a new array is created to contain
the result. If destination is t, the result is destructively placed in the
source array.
bit-orcl first second &optional third Function
Performs logical or operations on the complement of first with second on
bit arrays. The arguments must be bit arrays of the same rank and dimensions.
A new array is created to contain the result if the third argument
is nil or omitted. If the third argument is t, the first array is used to hold
the result.
