Imagemagick Convert PDF to JPEG: FailedToExecuteCommand `"gswin32c.exe" / PDFDelegateFailed
I have PDFs that I need to convert to images. I have installed Imagemagick. I have a PDF named a.pdf that I can open (it is not corrupt) in the folder C:\Convert\
From the command line I am trying
C:\Convert>convert a.pdf a.jpg
And I am getting the error.
convert.exe: FailedToExecuteCommand `"gswin32c.exe" -q -dQUIET -dSAFER -dBATCH -

UPDATE:
After the SO community helped me solve this issue I put together a little tool to batch convert images. Hope it helps somebody.

You need to install Ghostscript in order to rasterize vector files (PDF, EPS, PS, etc.) with ImageMagick. IM will shell out to Ghostscript when doing these manipulations (you can see it if you use the -verbose tag in your IM invocation). You could also use Ghostscript by itself to rasterize vector files.
