TuiBounds

A rectangular region in terminal cell coordinates (`$x`/`$y` from the top-left, in columns/rows), used throughout the TUI layer for viewport, node, and overlay placement.

public function __construct(int $x, int $y, int $width, int $height):

Parameters

Throws

\InvalidArgumentException If any of `$x`, `$y`, `$width`, `$height` is negative.

public function right(): int

The x-coordinate just past this region's right edge (`$x + $width`).

public function bottom(): int

The y-coordinate just past this region's bottom edge (`$y + $height`).

public function inset(int $amount): self

Returns a new region shrunk by `$amount` on every side (e.g. for padding). `$amount` is clamped to non-negative, and the resulting width/height are clamped to zero rather than going negative when `$amount` exceeds half of this region's size.
