to your LaTeX file. Let us suppose that the name of this file is
image.tex. Compile it with LaTeX and then apply dvips to the
image.dvi file, doing

dvips -E -o image.eps image

Then use Ghostscript with the -dEPSCrop option to turn it into a JPEG
file. Under Windows, I would do something like:

gswin32c -dSAFER -dBATCH -dNOPAUSE -sDEVICE#jpeg -dEPSCrop
   -sOutputFile#image.jpg image.eps
