No output file from GhostScript PDF to PNG conversion

Question

I have a two-page PDF I'm trying to convert to a PNG file. When I run:

gs -sDevice=pngalpha -o=gs-output-%d.png -r400 test1-0.pdf

I get:

GPL Ghostscript 9.07 (2013-02-14)
Copyright (C) 2012 Artifex Software, Inc.  All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
Processing pages 1 through 2.

%%HiResBoundingBox: 35.910001 35.910001 576.090022 756.090029

And then... nothing. No output files at all. Where am I going wrong?

You're so close you'll be mad ;-)

After a bit of manpage reading here's what worked for me:

gs -sDEVICE=pngalpha -ogs-output-%d.png -r400 test1-0.pdf

i.e. DEVICE instead of Device, and -o instead of -o=

In case it matters, my gs version is:

GPL Ghostscript 9.05 (2012-02-08)

Beautiful! Works like a charm on GPL Ghostscript 9.07 (2013-02-14) as well.

try this which works perfectly with me and it get a very good results:

-sDEVICE=pngalpha -o "$OUTPUTIMAGEFILE" -dFirstPage=1 -dLastPage=2 -dNOPAUSE -dGraphicsAlphaBits=4 -dTextAlphaBits=4   "$INPUTPDFFILE"

However i guess that using -r400 is for JPEG images not PNGS
