{
$image = '<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg     viewBox="0,0,40,30"   version="1.1"
xmlns="http://www.w3.org/2000/svg">
<rect x="0" y="0"     fill="#cd0000"/>
</svg>
';
$filename = 'ef.jpg';
/* $image = stripslashes($_POST['json']);
$filename = $_POST['filename'];*/
$unique = time();
$im = new \Imagick();
$im->readImageBlob($image);
$res = $im->getImageResolution();
$x_ratio = $res['x'] / $im->getImageWidth();
$y_ratio = $res['y'] / $im->getImageHeight();
$im->removeImage();
$im->setResolution($width_in_pixels * $x_ratio, $height_in_pixels * $y_ratio);
$im->readImageBlob($image);
$im->setImageFormat("jpeg");
$im->writeImage(__DIR__ . '/../../../Public/moban/images/1/humourised_'. $filename);
$im->clear();
$im->destroy();
}
