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

[NTG-context] absolute positioning?
Hello! What is the current most contextish way for absolute positioning of text (still using MK II)? I have to create a title page for a document where several frameless boxes of text have to be placed on the page. Is this still the layer mechanism?

extend your example with
\clip[width=.15\paperwidth,height=,hoffset=0pt,voffset=0pt]{\externalfigure..}
and you can see the difference.. (no picture in the smaller layer).
As I already mentioned, the size is (only?) significant, if you change
the default positioning (reference point). For example, you want to
place something with an offset of 2cm to the right bottom corner of the
layer. Therefore you need the exact width and height of the layer.
All default positioning (relative to top left corner of the layer)
doesn't care about the size, as there is no difference (no calculation
is needed).
I hope I have made myself clear.

{\externalfigure[layTest][width=.75\paperwidth]}
I was expecting to have the layTest figure cut after its width exceeds
the layer's width. It seems that this is unrelevant, i.e.
If I have instead of this:
\definelayer[layer2a][width=.15\paperwidth]
this:
\definelayer[layer2a][width=.75\paperwidth]
It's the same.
So, I cannot understand what width means for layers, as changing it has
no consequences (in my example).

Ah, thanks, I see the point.
In the posted example, I was mumbling about the reference Hans did
about overlays+layers.
As far as I saw, I think that the only solution to absolute positioning
is \setupbackgrounds.
As wiki says, \placelayer offsets to \text dimensions.
Am I right?

Using different layers, you can change the order of appearance
(background={1,2,3}|{1,3,2},..) for the layer content.
Using only one layer, all layer content is placed stack like; the
printing order is then fixed by the appearance order in the document
(last overprints prior).

I think the size is significant, if you use relative positioning
(preset=bottomright and alike).

Now, I tried with overlays and layers. That's fine. In any case, in a
second approach I simply used \setlayer to fill repeatedly the same
layer. The result seems to be the same.
What's the difference? Is it safe to use the second approach?
Then: changing layer dimension in \definelayer, I cannot see any
differences in the output.
Can anyone explain what it should happen?

[NTG-context] absolute positioning of figures
Hi to all, In case of presentations sometimes one has to combine many figures in the page, maybe overlapping for some parts. Something very easy in powerpoint. What's the best technique? Taking a look at the wiki and ot "It's in the details" manual it seems that layers, which can be placed according to absolute positions, are the ConTeXt solution to the problem. Is it so? I was in fact considering to create a simple python GUI app to allow a visual control on position of figures on a page, outputting ConTeXt code to be copied and pasted.

[NTG-context] Absolute positioning of grafics in ConTeXt
Hi all,
I'm quite new to ConTeXt, but I've been working with LaTeX for several years
now. Now I faced a problem which I'm not able to solve in LaTeX which
probably can be solved in ConTeXt:
I need a possibility to set grafics in a book on exact, absolute positions.
Now I found the way for background images, like in the attached example.
But obviously, normal text is written above the background image. I need
now a possibility like this but for foreground grafics.
So, how can I set the position of grafics absolutely in ConTeXt?
Thanks,
Johannes.
My example:

\enableregime [il1]
\mainlanguage [de]
\setuplayout [grid=yes,marking=on,horoffset=2cm,veroffset=2cm]

\setuppapersize [jo][a4]
\useexternalfigure[wr][dpm][type=png, width=5cm, height=4cm]
\definelayer[wr-layer]
\defineoverlay[wr-overlay][\composedlayer{wr-layer}]
\setupbackgrounds[page][background={wr-overlay}]

Yes, AFAIK the mechanism does not support this now (and I do not know, if it
sometimes will do -- it seems to me it is a relatively old part of ConTeXt
and Hans himself recommends you the layers :-).
Anyway, you would have to count positions and coordinates manually.
But there is always a way using generic TeX here:
\position(40,1){%
\hbox to 0pt{%
\hss
\vbox to 0pt{
-- a material to typeset or display --
\vss
}
}
Of course, this solution does not take into account all of ConTeXt dependent
(and very convenient and pretty) features like grid fitting etc.
It is a thing of your needs.
Have a nice day,
Martin

This surely works ok for "top left". But how can I guarantee
that "top right" has its *top right* corner in the position? I
would have to calculate the coordinates manually (depending on

Is this possible without using layers? IOW, it there some kind
of command that allows:
\somecommand[some setups]{content}
where the setups specify where the content should be
positioned, and towards where it should extend? (e.g.,
positioned in the top right corner, extending to the bottom
left)
This can be achieved via layers, but is it possible without?
