Converting from PDF to JPG

Post by Rocinant » 2011-02-28T13:37:01-07:00

I am trying to convert a PDF file to a JPG file using the following code:

Code: Select all

<?php
exec("convert -density 100 -colorspace rgb test.pdf -scale 200x200 test.jpg");
?>
but this doesn't do anything. Converting JPG to PDF files or PNG to PDF files is no problem...
The Imagemagick version I am using is ImageMagick 6.2.8 08/03/06 Q16
The Ghostscript version is GNU Ghostscript 7.07 (2003-05-17)
Running on a Unix server

I sincerely hope somebody can help me!
Thanks in advance!
Regards,
Rocinant

Hi,
Don't know about the php bit, but I can confirm that from a command line:

Code: Select all

convert -density 100 -colorspace rgb test.pdf -scale 200x200 test.jpg
works OK for me with gs 9.00, ImageMagick 6.6.6-9
Do you see any useful messages if you run it from a command line?
Cheers,
Peter

probably a stupid question but have to tested that "convert" is working from PHP and that you can get images out of it?

Your 6.2.8 version of IM is ancient (over 400 versions old) as is your Ghostscript. Perhaps you should upgrade if you can.

My kind provider has updated the ImageMagick version. GNU Ghostscript 7.07 is the latest GNU version of Ghostscript. Now, if I use the commands

Code: Select all

convert test.pdf test.jpg
or

Code: Select all

gs -sDEVICE=jpg -sOutputFile=test.jpg test.pdf
I get the following error message:
GNU Ghostscript 7.07: Can't find initialization file gs_init.ps

...
What could that be?

Kind regards,
Rocinant

The last problem, about the missing gs_init.ps seemed to be a directory with the wrong chmod-settings. After my provider solved that, it worked great.

Thank you all for you help!
