Convert JPG/PNG to SVG format using PHP

Question

How do I convert JPG/PNG to SVG using PHP?

I know that it will not be vectorised, but I need it in a SVG-format.

I dont want to use any other software than PHP.

Something like this:

<?php

$image_to_cenvert = 'image.jpg';

$content = file_get_contents($image_to_cenvert);

$svg_file = fopen('image.svg','w+');

fputs($svg_file,$content);
fclose($svg_file);

?>

Answer 1

You can embed PNG/JPEG to SVG, by php. Look there.

<?php
$file = __DIR__ . $path2image;
$path = pathinfo($file);
$ext = mb_strtolower($path['extension']);
 
if (in_array($ext, array('jpeg', 'jpg', 'gif', 'png', 'webp'))) {     
    $size = getimagesize($file);  
    $img = 'data:' . $size['mime'] . ';base64,' . base64_encode(file_get_contents($file));
}
?>
 
<img src="<?php echo $img; ?>">

If type == svg

$img = 'data:image/svg+xml;base64,' . base64_encode(file_get_contents($file));

For this conversion you need to install ImageMagick and potrace. potrace can convert pbm/pgm/ppm/bmp to svg. So at first we need to convert png/jpg to pbm/pgm/ppm/bmp using imagemagick. Than we will convert it to svg using potrace via command line. raster to svg

As i know your only chance to achieve that is to use imagick library but the format available depend on the settings so if you're on a shared server could not be possible do it.
