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.
