README

This library is a simple tool to convert pixelated images to SVG.

It optimises the svg file size by merging pixels in a single path.

Installation

composer require arnapou/pixelsvg

Renderer

The logic of the path rendering is in the Renderer you give to PixelSvg

Renderers	Example 1	Example 2	Example 3	Description

ByPixelRenderer	18.4 KB	7.6 KB	25.5 KB	One svg path by pixel.

From code

$filename = '/some/file/to/convert.gif';

$renderer = new \Arnapou\PixelSvg\Renderer\ByColorRenderer();
$pixelSvg = new \Arnapou\PixelSvg\PixelSvg($renderer);

$reader = new \Arnapou\PixelSvg\ImageReader\ImagickReader::fromFilename($filename);
$svgContent = $pixelSvg->render($reader);

⚠️ Prefer the use of Imagick for animated GIFs, because GD does not support it.
