Imagemagick PDF to JPG conversion failing
- by Scott
I'm trying to convert the first page of a PDF to a JPG. I'm pretty sure I got this to work with certain PDFs, but is it really possible that certain PDFs are made incorrectly and cannot be converted?
I tried running this first:
$ convert 10-03-26.pdf[1] test.jpg
And I got the follow:
Error: /syntaxerror in readxref
Operand stack:
Execution stack:
%interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push 1 3 %oparray_pop 1 3 %oparray_pop --nostringval-- --nostringval-- --nostringval-- --nostringval-- --nostringval-- --nostringval--

Current allocation mode is local
ESP Ghostscript 7.07.1: Unrecoverable error, exit code 1
convert: Postscript delegate failed `10-03-26.pdf'.
Running this instead:
$ convert -verbose -colorspace rgb '10-03-26.pdf[1]' test.jpg
I get the following:
Error: /syntaxerror in readxref

Why would the conversion fail?
Just as an aside, this is happening on a (gs) Grid-Service on (mt) Media Temple hosting. I cannot install programs on the server, but both Imagemagick and Ghostscript are installed
Thanks!
