Hi guys,

I'm a bit of a n00b to ImageMagick and I'm having trouble converting a PDF document to a JPG. The conversion seems to work on initial inspection but the output file is an unreadable JPG file. I'm running ImageMagick and GhostScript on a linux server. Has anyone had a similar issue?

Cheers in advance!

Supply some more info:
Imagemagick version
How are you working - command line, php etc.
Example input image if possible.
Example of output if possible.

ImageMagick-6.5.2-7

Currently working command line but the intention is to exec it in a PHP script.

PM'ed input and output.

I have had that problem I believe. I think it is due to the pdf being cmyk format and my ghostscript cannot handle that. To get around that, if that is the problem, try

convert -colorspace rgb image.pdf image.jpg

Thanks for the suggestion, I had a go but to no avail. I've tried to change the document in case it is also a document permissions issue (I had to try!), but again, no joy.

Strange thing is that the convert creates an image file of what looks to be correct filesize.

I think there is a problem with your input pdf; I have tried different things including Freds suggestion but get this error everytime using php. I didn't even get the output you did !

can you post your pdf?

I'll find one that I'm generating using FPDF, which will ultimately be my input, bear with me a second...

I have just created a pdf using Microsoft office 2007 and I get the same results. How did you create your pdf ?

404 Error with that link

Should be okay now, otherwise is there a way of attaching the doc to the board?

WOOPS New PC and I do not think I have installed Ghost script

Back in a 1/2hr or so - Dinner ready.

The link works now.

Very sorry for the false leads - installed Ghostscript now and it all works OK on the posted sample.

IM version 6.5.1

What result do you get for your posted pdf ?

This works just fine for me on IM 6.5.2-7 Q16 Mac OSX Tiger with Ghostscript ghostscript-8.61.tar.gz
