```
sub resize_pane($self, %args)
```

`resize_pane(pane => Pane|pane_id, width => positive_integer?, height => positive_integer?)`.

Resize a [`LibTmux::Pane`](/en/perl/latest/reference/libtmux-pane/) to the supplied positive width and/or height. tmux's layout constraints may affect the resulting dimensions; inspect another [`LibTmux::Snapshot`](/en/perl/latest/reference/libtmux-snapshot/) for observed values.

Returns `undef` after command acceptance. Performs I/O; failures propagate through [`LibTmux::X`](/en/perl/latest/reference/libtmux-x/). Captured objects are not modified.


```perl
    $server->resize_pane(pane => $pane, width => 100);
```
