Can you try \pagefigure, my solution was to scale a image to the
papersize and remove parts. \pagefigure includes a figure within a
TEXpage and you scale now the figure to the size of the document.
\starttext
\pagefigure[cow][width=\paperwidth,height=\paperheight]

Re: [NTG-context] Images centered on page : Solved
you can use \dontleavehmode in this case. yes, i know. \meaning\ \dontleavehmode gives \quitvmode \meaning\quitvmode gives \quitvmode hence \quitvmode is a primitive . \quitvmode The primitive instructs pdfTEX to quit the vertical mode and start typesetting a paragraph. \quitvmode has the same effect as \leavevmode definition from plain macro package. Note however, that \leavevmode may conflict with \everypar tokens list. No such risk while using \quitvmode instead The primitive has been introduced in pdfTEX 1.21a. \hskip1sp give more the sense of invisible touch ... -- luigi ... it's new . it's powerful . it's luatex . http://www.luatex.org ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

your mail remind me to something I wanted a long time ago but I was now
motivated enough to write it. Below is solution to fit a given image to
a page with the normal width and height but remove parts at the top and
bottom or left and right if the width height relation is different from
the one of the document.
I think Hans would be ablo to write a better solution but this all I
can do by myself at the moment.

[NTG-context] Images centered on page : Solved
Hello,
Thank you all very much. I'm pleased with number and quality of solutions to my
problem.
The winner solution is provided by Wolfgang Schuster. Simple \centeredbox{}
makes all the magic I need.
I was also amazed with quick porting of my Lua code for batch image processing
to native TeX script. I'm an imperative programmer to the marrow and never will
be able to do such things. Luckily, now we have embedded Lua!
