Ah, now I see, why the graphics was at the bottom before.
Thank you very much!
Here an example to show how I use it:
\usemodule[pre-stepwise]
\setupinteraction[state=start]
\definelayer[myBG]
\setupbackgrounds[page][background=myBG]
\def\PlaceAtPos{\dosingleempty\doPlaceAtPos}
\def\doPlaceAtPos[#1]#2#3{%
\getparameters[PAA][dx=0pt, dy=0pt, #1]%
\setbox\scratchbox\hbox{#3}%
\setlayer[myBG][%
x=\the\dimexpr\MPx{#2} - 0.5\wd\scratchbox\relax,
y=\the\dimexpr\paperheight-\MPy{#2}-\ht\scratchbox\relax,
dx=\PAAdx, dy=\PAAdy]{#3}}
\starttext
Place something exactly 2cm left from he\xypos{XXX}re.
Place something exactly 1 line below he\xypos{YYY}re.
Place something exactly he\xypos{ZZZ}re.
\StartSteps
\PlaceAtPos[dx=-2cm]{XXX}{\red something} \FlushStep
\PlaceAtPos[dy=\lineheight]{YYY}{\green something} \FlushStep
\PlaceAtPos{ZZZ}{\blue something} \FlushStep
\StopSteps
\stoptext
Cheers, Peter
