I use ghostscript for that. you can find it using google. You can
run it from the command line, or equivalently, spawn a shell command.

A simple version for windows would be:
gswin32c -sDEVICE=png256 -r300 -dBATCH -dNOPAUSE -q
-sOutputFile=output.png input.eps

And this is a snippet from my makefile for making png's from eps's (I
use Cygwin for a bash shell in windows, and good chunks of this code
are due to stuff I found on the web)
bbox=`cat $< | tr '\015' ' ' | head -100 | egrep "^%%BoundingBox" |
head -1 | sed -e 's/%%BoundingBox://g''` ;\
width=`echo $$bbox | awk '{printf("%i\n",$$3)}'` ;\
height=`echo $$bbox | awk '{printf("%i\n",$$4)}'` ;\
$(GS) -sDEVICE=png256 -r300 -dBATCH -dNOPAUSE -q
-dDEVICEWIDTHPOINTS=$$width -dDEVICEHEIGHTPOINTS=$$height
-sOutputFile=$@ $<

Hope this helps,

Mirko
