placefigure feature request ?

placefigure feature request ?

[-- Attachment #1.1: Type: text/plain, Size: 306 bytes --]


Hi all,

It seems this is for you, Hans:

It would be nice if placefigure can be able to detect if the best place
is the top or the bottom of the page accordingly to its call, i.e.:
if placefigure call is near to the top -> figure will go to the top
else figure will go to the bottom...

Cheers,

Renaud

hm, as long as it's ok that it's a rough heuristic ... i'll send you something to play with

A related point, which I didn't fiugre out how for my own TeX
figure-placement macros, is correct sequential numbering when some
figures are at the top of the page.  Some pseudocode on one page:

=============== snip ===================
\ref{figure:narrow} is a narrow figure.

\figuremacro{figure:narrow}{narrowfig.1}{A narrow figure.}

\ref{figure:wide} is a wide figure.

\figuremacro{figure:wide}{widefig.1}{A wide figure}
=============== snip ===================

Here \figuremacro figures out (sorry) that narrow figures go in the
margin and wide figures go at the top of the page.  But the page will
look funny: The narrow figure will be numbered, say, Figure 10, and
the wide figure will be Figure 11, but Figure 11 will appear before
Figure 10 on the page.  Which is disconcerting to the reader.  

One solution is to look at all the figures on the page and then number
them, instead of numbering them when \figuremacro is executed.  I
couldn't figure out how to do that in my TeX macros, but maybe there
are hooks into the context output routine for such tricks?

\setupfloats[numbering=nocheck]

I think I want the opposite.  The documentation for \setupfloats at
<http://texshow.contextgarden.net/> says

  New option:
  numbering           yes nocheck (default yes)
    nocheck causes no renumbering so it preserves figure's source order

My problem was that the source order (which is the order of first
reference, probably) is not the order on the page.  The wide figure
floats to the top of the page (because it's wide) even though its
source position is later than the narrower figure that fits in the
margin.

So 'numbering=yes' will number according to position on the page?

no, actually floats will be renumbered automatically unless nocheck is given; the problem is that the order in which margins etc flush plays a role then. 

I can imagine another solution but i need a dark rainy non-busy day for that

To avoid confusion:

When 'page' refers to the typeset result, then Hans' answer actually
means 'yes'. Or it should, at least. I remember files where I had to
run texexec twice though. I am not sure if that bug still happens,
so be careful.

Right, I meant in pages of the typeset result.  I'll watch for the need
to run texexec and make a minimal example if I find the problem.  

Meanwhile I've been experimenting in baby steps, and numbering=yes does
what I want, as does specifying nothing about numbering.  But
numbering=nocheck doesn't stop it, so I'm confused by what the nocheck
option does (doesn't cause me problems since the default is what I want,
but I'm curious).

Probaby I'm just using an old version of context since the texshow-web
says that numbering=nocheck is a new option.  My last attempt at
upgrading didn't go well (I have tetex-3.0) but maybe it's time to try
again.

$ texexec --version

               cont-en : ver: 2005.01.31  fmt: 2006.3.28  mes: english

With this output on the file 

$ texexec 2m

So the figures get renumbered.

even more minimal:

\useMPlibrary[dum]

\setupfloats[numbering=nocheck]

\starttext
\input tufte \placefigure[rightmargin]{first} {\externalfigure[dummy]} \par
\input knuth \placefigure[top]        {second}{\externalfigure[dummy]} \par
\stoptext


does commenting the no check line makes a differnece? 

nocheck: top=2, margin=1 
yes    : top=1, margin=2  (default behaviour)

No difference.  I get the default behavior in both cases, and both log
files mention the renumbering:

$ texexec 3.tex > somewhere
$ mv 3.log 3-nocheck.log
[comment out the nocheck line]
$ texexec 3.tex > somewhereelse
$ grep renumber 3{,-nocheck}.log
3.log:floatblocks     : 1 renumbered / figure 1 => 2
3.log:floatblocks     : 2 renumbered / figure 2 => 1
3-nocheck.log:floatblocks     : 1 renumbered / figure 1 => 2
3-nocheck.log:floatblocks     : 2 renumbered / figure 2 => 1

Maybe this context installation is too old for nocheck.  On the other
hand, it should complain then?

I tried it on context live (2006.04.04), and it works as hoped (figure 2
is the on on top of the page with numbering=nocheck, otherwise it's
numbered in page order).  Definitely I need to do an upgrade.

But I noticed another problem: The context-live pdf is black/white,
whereas on my system the figures come out in color.  I could reproduce
the difference with the following:

$ texexec --pdf 3  => 3.pdf is B/W

versus

$ texexec 3.tex
$ dvips 3
$ ps2pdf 3.ps   => 3.pdf is in color

texexec --color makes the two pathways give identical pdf files, but
shouldn't they also be identical (and B/W) without the --color?  Or is
that too much of a mess, to inquire into what colors the metapost (or
other EPS) figures are doing.

This is 'wrong'. Normally, your output should be b/w unless
you have \setupcolors[state=start] in your document somewhere,
but ConTeXt does not know how to convert your images to
greyscale in the dvips case.

(actually, with a newish dvips, it should be possible to add
a postscript header file to do the conversion, but I do not
know enough about that to set it up).

Taco's msg about no meaning yes made me wonder: what's the special case
or problem you were thinking of?

Perhaps Holland in the winter can offer the dark, rainy day (just like
here in Boston, USA) but the 'non-busy' may be more difficult.

I've been experimenting a bit with the code, and it is much appreciated.

I added \unprotect..\protect and it compiled fine.  The figure numbering
is the order in the source files, thanks to the numbering=nocheck;
reading down the page it is 3->1->2.  Then I felt bold and commented out
the numbering=nocheck.  It does one clockwise rotation of the numbers:

floatblocks     : no block given
floatblocks     : 1 renumbered / figure 1 => 3
(/home/sanjoy/texmf/tex/context/base/pdfr-ec.tex)
floatblocks     : 1 placed
(/home/sanjoy/texmf/tex/context/sample/tufte.tex)
floatblocks     : no block given
floatblocks     : 2 renumbered / figure 2 => 1
floatblocks     : 2 placed
(/home/sanjoy/texmf/tex/context/sample/tufte.tex)
floatblocks     : 3 renumbered / figure 3 => 2
floatblocks     : 3 placed

If it had done a anticlockwise rotation, the figure numbers would have
been right (1->2->3 reading down the page).  Is it because the figure
renumbering does not know of the change to fallback=bottom (from
fallback=here)?

I included the code for numbering=text, to make the tex file below.
Sadly, the figures are numbered 3->1->2 (i.e. as if numbering=nocheck
were given).  I also tried the context live and got the same order.  Am
I doing something silly?

are you sure that you put the code in the right spot? (both float order patched!)

I hadn't thought the location mattered until just now!  But I'm not sure
where the ideal spot is.  Oh, do you mean that I should patch
page-flt.tex itself (and rebuild the formats, of course)?  It has one
\redofloatorder.  Instead I had just been inserting your magic in the
example source file itself, like so:
