Resizing .eps and Saving as .jpg with Imagick in PHP

I am trying to resize and save an .eps file to a .jpeg with Imagick,

I have tried resizeImage, scaleImage, setImageResolution, and I've tried writing to .png, but the result is always very bad. I've tried setting the compression quality to 100, and I've tried various resizeImage filter and blur params. 

$imagick = new Imagick();
$imagick->readImage($file);

$imagick->resizeImage($width, $height, imagick::FILTER_CATROM, 1);

$imagick->setImageFormat('jpeg');

return $imagick->writeImage($name);

Is there some magic I am missing?

Edit: I've read somewhere about similar issues being Ghostscript related, I have the Ghostscript port installed. How can I verify it is working?

Solution

  • For the record the solution was to execute image magick via the shell:

    e.g.

    $cmd = escapeshellcmd("convert -resize '{$width}x{$height}' -density 300 -flatten {$file} -colorspace rgb {$jpeg}");
exec($cmd, $out, $return_var);
