Re: [NTG-context] Absolute positioning of \startcombination... \stopcombination
Thanks for your reply Pablo. I didn't see it till just now because for
some reason it ended up in my junk folder, along with a number of other
ConTeXt messages. You will probably have seen my reply to the list with
the three solutions, now we have four!
Yep, I know that A4 is the default page size and I always start with
that but sometimes I play about with page sizes when typesetting and so
can just change when coding.
In the document I'm working on, some pages will only contain images
and/or combination of images so I went down the Layers route since this
also allows me to absolutely position these images on the page.
Thanks again for your help!
Best Wishes

Hi Keith,
I think the following sample might achieve what you want:
\showframe
\setupexternalfigures[location={default}]
\setuplayout
[backspace=2.5cm,
topspace=1cm,
height=28cm,
width=17cm,
header=0cm,
footer=0.75cm,
]
\definelayer[test3]
%[x=.5\paperwidth, y=.5\paperheight]
[x=.5\textwidth, y=.5\textheight]
%\setupbackgrounds[page]
\setupbackgrounds[text]
[background=test3]
\starttext
\setlayer[test3][location={middle}]
\framed[offset=overlay]{{\startcombination[nx=3,ny=1,distance=15mm]
{\externalfigure[cow][width=15mm]}{}
\rotate[rotation=90]{\externalfigure[cow][width=15mm]}{}
{\externalfigure[cow][width=15mm]}{}
\stopcombination}}
\null
\stoptext
BTW, A4 portrait is the default page size.
\setupbackgrounds is the standard way to place layers.
Page and text centering would require different positions (I have
commented out the option for page centering).
I hope it helps (since I’m not sure I’m getting your point here),
Pablo

Re: [NTG-context] Absolute positioning of \startcombination... \stopcombination
Hi,
I've experimented this morning with the solutions suggested by Wolfgang
and Alan in reply to my post.
The solution is really quite simple as suggested by Wolfgang i.e.
\centerbox{..}. I have applied this to the code and I now have three
different solutions to my initial problem. The Joy of ConTeXt!
Thanks again Wolfgang and Alan.

Or you could put the combination in a frame:
\startparagraph [align=middle]
\startframed [frame=off,offset=\zeropoint]
\startcombination [nx=3,ny=1]
{first} {}
{second}{}
{third} {}
\stopcombination
\stopframed
\stopparagraph
