epstopdf extracts the bounding box from the EPS file and prefixes the file
with some additional Postscript code to shift the lower left corner to
(0,0) and to set the pagesize to the size of the EPS. After that the gs
command is quite simple:

gs -q -sDEVICE=pdfwrite -dAutoRotatePages=/None -sOutputFile='$OutputFilename' '$InputFilename' -c quit

-r res -sDEVICE=png256

You could give the pagesize as gs option (-g'width'x'height'). The lower
left corner might already be at (0.0)
