README

Page geometry, boxes, and format definitions for PDF documents.

If this project is useful to you, please consider supporting development via GitHub Sponsors.

Overview

tc-lib-pdf-page manages page sizing, orientation, box definitions, and related geometry metadata.

It provides the structural model that document builders use to define media boxes, orientation changes, and page-level defaults consistently. Centralizing these rules improves correctness in multi-page layouts and simplifies downstream rendering code.

Features

Page Model

• Standard and custom page size handling
• Orientation and unit conversion helpers
• Region and box definitions (CropBox, TrimBox, and related metadata)

Integration

• Supports PDF composition stacks that need deterministic page geometry
• Pairs with color/encryption libraries for complete page objects
• Typed exceptions for invalid layout parameters

Requirements

• PHP 8.2 or later
• Extensions: date, zlib
• Composer

Installation

composer require tecnickcom/tc-lib-pdf-page

Quick Start

<?php

require_once __DIR__ . '/vendor/autoload.php';

    new \Com\Tecnick\Pdf\Encrypt\Encrypt(false),
    false,
    false
);

$dims = $page->setBox([], 'CropBox', 0, 0, 210, 297);
var_dump($dims['CropBox']);
