The easiest way to get jpeg output?

The easiest way to get jpeg output?

[context]

Hello,

 I need transform some presentation into series of
 jpeg files. Is it possible directly from ConTeXt or
 I have to use some external tools for conversion?
 What is the easiest way in any case?

-- 
best regards
ml.

Hi

You can make a script to export pages from your document using ghostscript like that:

gs -dFirstPage=1 -dLastPage=1 -sDEVICE=jpeg -r150 -sOutputFile=page1.jpg -dBATCH -q -dNOPAUSE -dGraphicsAlphaBits=4 -dTextAlphaBits=4  -dMaxBitmap=50000000 document.pdf

use ghostview/ghostscript to convert your pdf presentation into jpg
(device jpg). but i'm clueless, why someone wants a pixel based
representation, when (s)he already has a pdf document.

And incase you do need that, please go for png instead of jpeg. Jpeg 
is a horrible for format to store a few black stokes on a white 
background.
