Vector Graphics Library
=======================

[](#vector-graphics-library)

PHP library for OO-modeling of vector graphics.

Objectives
----------

[](#objectives)

This library is designed to construct and describe general vector graphics independent of its application backend. These descriptions are intended to separate the definition on an graphic/chart/... and its representation.

A graphic could be serialized into various document types using there capabilities for vectorized representations. Currently supported/planed serializations are:

- export as standalone SVG content
- serialize into a Zend-PDF page
- serialize into an Imagine image

Installation
------------

[](#installation)

To add vector-graphics as a local, per-project dependency to your project, simply add a dependency on `mwoerlein/vector-graphics` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file:

```
{
    "require": {
        "mwoerlein/vector-graphics": ">0.2"
    }
}
```

Example Usage
-------------

[](#example-usage)

The following example generates a svg-image containing a pentagram in a red circle inside of a square

```
$graphic = new Graphic();
$graphic->setViewportCorners(-50, -50, 50, 50);

$graphic->addRectangle(-49, -49, 98, 98)->setStrokeWidth(2);
$graphic->addCircle(0, 0, 45)->setFillColor('red', 0.5);

$radius = 40;
$path = new Path($radius * sin(0./5. * pi()), $radius * cos(0./5. * pi()));
$path->lineTo($radius * sin(4./5. * pi()), $radius * cos(4./5. * pi()));
$path->lineTo($radius * sin(8./5. * pi()), $radius * cos(8./5. * pi()));
$path->lineTo($radius * sin(2./5. * pi()), $radius * cos(2./5. * pi()));
$path->lineTo($radius * sin(6./5. * pi()), $radius * cos(6./5. * pi()));
$path->close();
$graphic->addPath($path);

header('Content-Type: image/svg+xml');
echo (new SVGWriter())->toSVG($graphic, 10, 10);

```
