hi there
ImageMagick doesn't actually convert pdfs, all it does is to invoke
Ghostscript. You might want to call GS directly to gain more control
over it. Example of a GS command:
gs -q -sDEVICE=jpeg -dBATCH -dNOPAUSE -dFirstPage=1 -dLastPage=1
-r<OUTPUT RESOLUTION> -sOutputFile=<OUTPUT>.jpg <INPUT>.pdf 2>&1
this rasterizes first page of <INPUT>.pdf into <OUTPUT>.jpg with
resolution 300.
