适用于与lib16 SVG Builder一起使用。

使用Composer安装

此包可在 packagist 上找到，因此您可以使用 Composer 安装它。在您的shell中运行以下命令

composer require lib16/graphics

基本用法

<?php
require_once 'vendor/autoload.php';

use Lib16\Utils\NumberFormatter;
use Lib16\Graphics\Geometry\VectorGraphics as G;

$center1 = G::point(100, 150);
$center2 = G::point(80, 290);
$center3 = G::point(210, 290);

$star = G::star($center3, -7, 40, 40 * G::STAR_RADIUS_7_3);
$rect = G::rectangle($center3->copy()->translate(-50, -52), 100, 100);
G::skewX($center3, G::deg(-30), $star, $rect);

$path = G::path()
    ->star(G::point(50, 50), 5, 40, 40 * G::STAR_RADIUS_5_2)
    ->star(G::point(150, 50), 8, 40 * G::STAR_RADIUS_8_3, 40)
    ->star(G::point(250, 50), 6, 30, 40, 40)
    ->star($center1, 6, 70)
    ->ellipse($center1, 60, 20, G::deg(30), true)
    ->ellipse($center1, 60, 20, G::deg(90), true)
    ->ellipse($center1, 60, 20, G::deg(150), true)
    ->rectangle(G::point(170, 95), 110, 110)
    ->roundedRectangle(G::point(175, 100), 100, 100, 20, true)
    ->circle(G::point(225, 150), 45)
    ->sector($center2, G::deg(30), G::deg(175), 50)
    ->sector($center2, G::deg(290), G::deg(325), 50)
    ->ringSector($center2, G::deg(175), G::deg(275), 60, 50)
    ->polygon($rect)
    ->polygon($star)
    ->toSvg(new NumberFormatter(4), new NumberFormatter(2));
