Error codes

Post by fabrice4821 » 2016-09-28T12:02:21-07:00

Hi,

I'm using imagemagick in my php code to convert PDF file in JPG pictures.

I'm using :

Code: Select all

exec('convert -density 300 -trim "'.$pdf_file.'" -quality 80 -resize 800 "'.$save_to.'"', $output, $return_var);
Some times, in the return_var I have the error number 9 or 1.

What are this errors ?

Best regard.

I do not know. They sound like unix numbers. I believe IM only shows 0 or 1.

You should put your -trim after reading the PDF file and include +repage, for proper IM 6 or 7 syntax.

Please always provide your IM version and platform when asking questions, since syntax may differ.

If you want to see actual error messsages then change your command to

Code: Select all

<?php
exec('convert -density 300 "'.$pdf_file.'" -trim +repage -resize 800 -quality 80  "'.$save_to.'"' 2>&1, $output, $return_var);
foreach($output as $text)
{echo "$text<br>";}
?>
You do not say what the output image format is? If JPG then -quality is OK. But if some other format such as PNG, then -quality values are totally different. See http://www.imagemagick.org/script/comma ... hp#quality

Hi,

The output image format is jpg.

When I have the error 9 in $return_var, there are not information in $output

When I have the error 1 in $return_var, there are in $output:

It tells you that your very old version (v8.71) of Ghostscript had problems reading the PDF. Try upgrading GS.

The return is:
Array ( [0] => Version: ImageMagick 6.6.0-4 2015-11-27 Q16 http://www.imagemagick.org [1] => Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC [2] => Features: OpenMP [3] => [4] => 8.71 )
I'm on shared hosting and I can't upgrade the ImageMagick version.
Is there another solution for use this libraries ?

That version is over 350 versions old. I suggest you try to get your ISP to upgrade or threaten to go to a different ISP.

You never answered the question about what version of ghostscript you are using.
