Converting layered AI File to PNG

Post by Lagily » 2018-10-15T14:22:33-07:00

Hello

I cannot seem to be able to convert a layered AI File properly into a PNG, at least one layer seems to be missing. I am able to convert it using command line properly and am wondering how I can achieve the same using the PHP library, can anyone here help me?

This works just fine:

Code: Select all

    $convertCmd = "magick convert " . APP_ROOT . "/user_content/logo_oetwil_ps.ai " . APP_ROOT . "/user_content/logo_oetwil_ps.ai.png";
    exec($convertCmd);
This does not contain all the layers in the PNG:

Code: Select all

    $im = new Imagick();
    $im->readImage(APP_ROOT . "/user_content/logo_oetwil_ps.ai");
    //$im->mergeImageLayers(\Imagick::LAYERMETHOD_FLATTEN); // This does not seem to help either
    
    $im->setImageFormat("png");
    header("Content-Type: image/png");
    echo $im->getImageBlob();

Please always provide your Imagemagick version and Platform/OS. Also provide your input AI file so we can check out the issue.

This works fine for me on Imagemagick 6.9.10.12 Q16 Mac OSX with Ghostscript 9.24.

Code: Select all

convert logo_oetwil_ps.ai ai.png
Check your version of Ghostscript and be sure it is current.

For IM 7, use magick rather than convert.

Yes, the command line one works, but the PHP one does not, that is the problem... any idea why?

It is likely due to an older version of Ghostscript. You can check your version with PHP exec() calling gs --version.

<?php
exec("gs --version",$out,$returnval);
foreach($out as $text)
{echo "$text<br>";}
?>

If you find it old, then you should upgrade it. If you are on a hosted platform, then you will need to ask the hosting provider to do the upgrade.
