Vector Graphics Library
PHP library for OO-modeling of vector graphics.
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
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:
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);
