auto
padEdge
(
string direction = "both"
Iterator
size_t N
SliceKind kind
)
(
Slice!(Iterator, N, kind) s
,
size_t[N] lengths...
)
template padEdge(size_t[] dimensions, string[] directions)

Parameters

direction: padding direction. Direction can be one of the following values: "both", "pre", and "post".
s Slice!(Iterator, N, kind): Slice
lengths size_t[N]: list of lengths for each dimension.

Return Value

Type: auto

Examples

import mir.ndslice.allocation: slice;
import mir.ndslice.topology: iota;

auto pad = iota([3], 1)
    .padEdge([2])
    .slice;

assert(pad == [1, 1,  1, 2, 3,  3, 3]);

import mir.ndslice.allocation: slice;
import mir.ndslice.topology: iota;

auto pad = iota([2, 2], 1)
    .padEdge([2, 1])
    .slice;

assert(pad == [
    [1,  1, 2,  2],
    [1,  1, 2,  2],

    [1,  1, 2,  2],
    [3,  3, 4,  4],

    [3,  3, 4,  4],
