If you want to resize a vector-graphics image (such as SVG) to a certain dimension in pixels, without losing quality, you have to do this:



<?php



$im = new Imagick();

$im->readImage("/path/to/image.svg");

$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->readImage("/path/to/image.svg");

// Now you can do anything with the image, such as convert to a raster image and output it to the browser:

$im->setImageFormat("png");

header("Content-Type: image/png");

echo $im;



?>



It took me a couple or so days to figure this out, I hope this saves someone else's time! Have fun! :-)
