Unable to convert from PNG to SVG using rest7.php

[sibbu2005]

Here is my code `<?php include 'api-master/rest7.php';

$im = imagecreatefrompng('bhobj_282.png');

$svg = convertImage7($im, 'svg');

if ($svg) { $myTextfile = fopen('output.svg', "w"); file_put_contents('output.svg', $svg); fclose($myTextfile); } else { die('Unable to convert');

} ?>`
