convert works from command line but not php shell PDF

[Jeremy]

Hey guys I'm working with Imagick version Version: ImageMagick 6.9.3-6 Q16 x86_64 2016-04-12

From the command line I can type: convert test.pdf test.png and it works flawlessly.

From a php script if I type exec('convert test.pdf test.png') I get the error convert: no images defined `test.jpg' @ error/convert.c/ConvertImageCommand/3252.

I can also do exec('convert test.png test.jpg') and it works. It seems to just dislike PDF's from exec.

The file exists. Any clues to what's going on?

Thanks.

From a php script if I type exec('convert test.pdf test.png') I get the error convert: no images defined `test.jpg' @ error/convert.c/ConvertImageCommand/3252.

Are you sure you have the correct message? How can you have a message about JPG, when your input and output are not even JPG?


Best guess - It would appear that your Imagick cannot find where ghostscript is located

[Jeremy]

Ok I ran
$cmd = "convert -list delegate | grep -Ei '(PDF|PS|EPS|JPG|PNG)'";
exec($cmd, $out);

(from a php script) and got:

I believe that list is the IM defaults and not what delegates you actually have registered with IM. I think this problem has been answered before. I suggest you search the archives and see if you can find the issue. You could try putting the full path to gs in your delegates.xml file. Also what do you get via PHP from

convert -version

Does it list gs or gslib?

Sorry I am not an expert on PHP or Imagick.

[Jeremy]

It lists:

array(5) {
[0]=>
string(77) "Version: ImageMagick 6.9.3-6 Q16 x86_64 2016-04-12 http://www.imagemagick.org"
[1]=>
string(57) "Copyright: Copyright (C) 1999-2016 ImageMagick Studio LLC"
[2]=>
string(54) "License: http://www.imagemagick.org/script/license.php"
[3]=>
string(28) "Features: Cipher DPC Modules"
[4]=>
string(73) "Delegates (built-in): bzlib freetype jng jpeg ltdl lzma png tiff xml zlib"
}

[fmw42]

It does not list gs. So IM cannot find GS under PHP. If you do the same in a terminal (convert -version) do you get gs listed?

Find were Ghostscript resides?

find / | grep "gs"

see if it is at /usr/local/bin/gs or /usr/bin/gs or somewhere else.

Then in a terminal

echo $path

Then do the same via PHP exec().

Is gs in the $PATH for PHP?

[Jeremy]

The problem is though it lists the same from the command line when I run

convert -version

and the command line works fine.

My gs path is:
/usr/local/bin/gs

[fmw42]

What platform? I am told that gs is not listed from Windows from convert -version.

On my Mac I get:

convert -version

try editing your delegates.xml file to add the full path to gs

Heres the contents of my Delegates file:

Delegate command file.

Commands which specify

specify the rules for converting from in_format to out_format These
rules may be used to translate directly between formats.

Commands which specify only

decode="in_format"

specify the rules for converting from in_format to some format that
ImageMagick will automatically recognize. These rules are used to
decode formats.

Commands which specify only

specify the rules for an "encoder" which may accept any input format.

For delegates other than ps:*, pcl:*, and mpeg:* the substitution rules are
as follows:

%i input image filename

%u unique temporary filename
%Z unique temporary filename
%# input image signature
%b image file size
%c input image comment
%g image geometry
%h image rows (height)

%m input image format
%p page number
%q input image depth
%s scene number
%w image columns (width)
%x input image x resolution
%y input image y resolution

Set option delegate:bimodal=true to process bimodal delegates otherwise they

[fmw42]

try editing it where I marked the blue gs in my previous post.

[Jeremy]

Yeah the only thing that did was break my command line version.

[fmw42]

Did you answer my earlier questions:

Find were Ghostscript resides?

find / | grep "gs"

see if it is at /usr/local/bin/gs or /usr/bin/gs or somewhere else.

Then in a terminal

echo $path

Then do the same via PHP exec().

Is gs in the $PATH for PHP?

What are the above two PATHs?

Your PHP environment probably needs to know where ghostscript resides. But I do not know enough about PHP to tell you where or how.

Did you install the Ghostscript fonts also? Did you install Ghostscript at the same place as where Imagick gets installed? Perhaps you need a copy there (along with the GS fonts).

Have you searched this forum for similar problems? It seems to me that it has come up before.

see for example:
http://stackoverflow.com/questions/2759 ... -pdf-input
http://php.net/manual/en/imagick.construct.php
https://github.com/delphian/drupal-conv ... P-and-MAMP

Sorry, after the above, if it still does not work, then I am out of ideas.

[Jeremy]

Thanks for the research, I believe I've read those but I'll take another look.

I do think it knows where GS is because I can go from something to a PDF via exec.

I.E.

exec('convert test.jpg test.pdf');

[snibgo]

I do think it knows where GS is because I can go from something to a PDF via exec.

This doesn't prove GS is working.

GS is used only to read PDF. It isn't used to write PDF.

[EDIT for clarity.]

[fmw42]

GS is used only to read PDF. It isn't used to write PDF.

Snibgo is correct. But to be clear, the original discussion was about conversion from pdf to png, so that would depend upon Ghostscript.

I still believe you need to get the path to ghostscript into your PHP environment PATH and you have not answered my questions about that twice now.
