Hello, I really like ImageMagic. I don't want a substitute. It's just taking me a while to get things working. Please bare with me.

MY PROBLEM
*****************************************************************
Whilst I can now convert .tif files to .png, when I attempt to run convert 1.pdf -scale 500 11111.png it fails. I get the output as appended below.

MY SYSTEM
*****************************************************************
Windows 7 64bit
GhostScript 9.04 for Windows 64 bit ( http://www.ghostscript.com/download/gsdnld.html )

C:\tmp>convert 2.pdf -scale 500 22222.png
(get the same error message as above)

I am sure I must be doing something stupid here because I am surely not the only one needing to convert .pdf's to another format. Anyone got any ideas where my ignorance lies?
Thank-you in advance, Michelle

Okay I've got it working. For anyone else with the same problem I think its 64-bit related. I had installed ghost script 64 bit version. I also installed it after installing image magick.

THE FIX WHICH WORKS FOR ME: (on windows 7 64 bit)
1. Uninstall ghost script and image magick
2. Install ghost script 32 bit version
3. Install image-magick 32 bit version

And now this works for me: convert 2.pdf -scale 500 22222.png

@Michelle -

THANK YOU SO VERY MUCH!!!

I have been pulling out what I have left of my hair for the last 4 hours trying to get this to work! Followed your instructions and now I too can convert PDF > JPG !

Same setup: Win 7 - 64 bit, but I too had installed IM first, 64 bit version, then GS and also the 64 bit version.

Now I just have to figure out how to do a batch conversion; all PDFs in a directory to same-named JPGs. I'm sure there's an answer here somewhere ... off to track it down!

Thanks again

Cheers!
Lyle

Found it!

Mogrify

To convert all the PDFs in one folder to JPGs while keeping the same filename for the JPGs as the PDFs:

mogrify -format jpg *.pdf

That's it Exactly what I was looking for!
