What version of IM do you use? What version of Ghostscript?

If Ghostscript is older than 9.19, or is 9.22, I suggest you upgrade it.

If that doesn't help, please link to your input PDF.

I am no expert, but your code does not look like Imagick code. And I do not see Imagick initialized.

See http://us3.php.net/manual/en/book.imagick.php

Sorry, I do not know much about Imagick. So you will need help from someone who actually uses it.

Have you tried creating a simple Imagick command to test that it works independent of any database calls. That is usually a good way to test and develop. Get a small part working, then keep adding until it breaks and figure out then what caused the break.

I suggest you provide a link to your input PDF, so we can try conversions with different versions of IM and Ghostscript.

Following up with what user snibgo has said, do you have Ghostscript installed in your ImageMagick and can PHP Imagick find it. Often with PHP Imagick, it cannot use the same ENV variables as ImageMagick and so cannot find Ghostscript. To solve that, you must add the full path to "gs" within any line for PS, PDF, EPS, that call "gs" in the delegates.xml file.

You should write a simple PHP Imagick call that simply converts a PDF file to say PNG or TIFF or JPG and see if that works. Do not include any database or variables, just write code that does the convert and see if the result looks correct.

hello good afternoon, we had already tried the ghostscript, the problem is apparently the version of php 7.2, which comes to install on ubuntu 18, we did the installation on a server with ubuntu 16, which has php 7.0 and worked perfectly, I do not know the reason for this error but the solution we could do was to make a downgrade of the operating system.

thanks for the help
