Placing boxes anywhere on the page

Placing boxes anywhere on the page

[Peter Davis]

[-- Attachment #1.1: Type: text/plain, Size: 329 bytes --]

Is there a way to place a box at some specified x and y position on the
page, and then typeset one or more paragraphs of text into the box?  I guess
I'm thinking of something like LaTeX's minipage, but with the ability to
specify absolute coordinates, rather than just position relative to the
current baseline.

Thank you,

Use layers (untested):

\definelayer[textbox][width=\paperwidth,height=\paperheight]

\setupbackgrounds[page][background=textbox]

\def\starttextbox
  {\dosingleargument\dostarttextbox}

\def\dostarttextbox[#1]%
  {\def\stoptextbox{\setlayerframed[textbox][#1]{\getbuffer[textbox]}}%
   \startbuffer[textbox][starttextbox][stoptextbox]}

\starttext

\starttextbox[x=2cm,y=4cm,width=8cm,frame=off]
some text ...

more text ...
\stoptextbox

\starttextbox[x=6cm,y=12cm,width=8cm,frame=off]
another example ...
\stoptextbox

\stoptext

Thanks, Worfgang!  I just tried this.  I don't see any errors, but I don't
see any PDF either.  Here's the log file:

Layers or overlays are certainly the right method. But there is also the
\position macro:

\setupframed[foregroundstyle=\bfc]
\setuppositioning[state=overlay, unit=cm, xoffset=0.5\textwidth,
  yoffset=0.5\textheight]
\starttext
\startpositioning
  \position(0,0){\framed{0,0}}
  \position(-5,-5){\framed{-5,-5}}
  \position(-5,5){\framed{-5,5}}
  \position(5,-5){\framed{5,-5}}
  \position(5,5){\framed{5,5}}
\stoppositioning
\input tufte
\input tufte

\stoptext

Force ConTeXt to produce a page with „\page[empty]“ or „\dontleavehmode\page“ when you have enough material for one page or when you’re at the end of your document.

Thanks again!  Now I get output,  But text isn't getting composed inside
these boxes.  It's just all output on one line.  I tried a couple of
paragraphs, and just saw the the end of one and the beginning of the next
one one line.

Sorry if there's some obvious remedy for this.  I'm still new to ConTeXt.

Thank you.

Thanks!  I didn't find much in the ConTeXt reference manual on this.  Is
there more info somewhere?

Thank you.

Here is a complete working and tested example:

\definelayer[textbox][width=\paperwidth,height=\paperheight]

\setupbackgrounds[page][background=textbox]

\def\starttextbox
   {\dosingleargument\dostarttextbox}

\def\dostarttextbox[#1]%
   {\def\stoptextbox{\setlayerframed[textbox][width=6cm,align=normal,frame=off,#1]{\getbuffer[textbox]}}%
    \startbuffer[textbox][starttextbox][stoptextbox]}

\starttext

\starttextbox[x=2cm,y=4cm]
The Earth, as a habitat for animal life, is in old age and
has a fatal illness. Several, in fact. It would be happening
whether humans had ever evolved or not. But our presence is
like the effect of an old-age patient who smokes many packs
of cigarettes per day – and we humans are the cigarettes.
\stoptextbox

\starttextbox[x=6cm,y=12cm,width=8cm]
Thus, I came to the conclusion that the designer of a new
system must not only be the implementer and first
large-scale user; the designer should also write the first
user manual.

The separation of any of these four components would have
hurt \TeX\ significantly. If I had not participated fully in
all these activities, literally hundreds of improvements
would never have been made, because I would never have
thought of them or perceived why they were important.

But a system cannot be successful if it is too strongly
influenced by a single person. Once the initial design is
complete and fairly robust, the real test begins as people
with many different viewpoints undertake their own
experiments. 
\stoptextbox

\page[empty]

\starttextbox[x=4cm,y=6cm,width=8cm,align={right,nothyphenated},frame=on]

So that is still used? (If so, I should look into optimizing and cleanup 
as it's real old code).

Seems like a feature that's nice to have; it mirrors the texpos
package for LaTeX. Please update it.

It does not really mirrors something (so it's not something users expect 
to be there I guess) ... if I remember right I made it for putting 
hyperlinks on specific places as I didn't want to use pictex for that. 
We have layers that provide a better mechanism.

Anyway, it's not that much code so it can stick around (I even see a 
dutch comment so it's real ancient).

\position is (will be) fully documented in the updated reference manual. :)

(I was not aware of positioning, either!)
Again, we see that ConTeXt is quite rich,
and our documentation lags far behind.

As to layers, see:
http://wiki.contextgarden.net/Layers

We also have collectors:

Hans,

1. It would be natural to have \startframed\stopframed

2. A collector may be more natural than layers (used as a page background).
(As seen through "Force ConTeXt to produce a page with „\page[empty]“ or 
„\dontleavehmode\page“ when you have enough material for one page or when 
you’re at the end of your document.")

Is there any need for some helper macros, or do we simply need a
few good examples?

Alan

I upgraded the code a bit and it's now in pack-pos.mkiv.

The \startpositioning macro also accepts an optional settings argument 
now.
