Float placement problem

Float placement problem

[Pontus Lurcock]

Hello,

I've recently updated my standalone (32-bit Linux) ConTeXT from
2011.02.25 to 2011.09.20, and I'm now having some trouble with float
placement. I'm using MkIV. I'm trying to have figures protruding into
the outer margins with a double-sided layout, as described here:

http://wiki.contextgarden.net/Floating_Objects#Protruding_Floats_in_Double-Sided_Documents

Here is my minimal example:

\setuplayout[location=doublesided]
\setuppagenumbering[alternative=doublesided,location={margin,header}]
\setupfloat[figure][location=inner]
\showframe
\starttext
% An extra page. \page[yes]
\dorecurse{4}{
\placefigure[]{caption}{\externalfigure[cow.pdf][width=17cm]}}
\stoptext

With version 2011.02.25 this produces the desired result; with
2011.09.20, the first figure is placed correctly, and all subsequent
figures protrude in the same direction, whether they're on an even or
odd page. So in the given example they all protrude to the right. If
an extra page is inserted at the start so that the first figure is on
an even page, they all protrude to the left.

Does anyone have any ideas or insights?

Thanks in advance,

Pont

Hmm, I guess not. I will put a note on the wiki page and revert to my
old ConTeXt version for now. If anyone has an idea for a workaround I
would be glad to know of it.

hm , it looks like a bad match with  between width=17cm and textwidth
This extreme example seems to works
\setuplayout[location=doublesided,width=20pc]
\setuppagenumbering[alternative=doublesided,location={margin,header}]
\setupfloat[figure][location=inner]
\showframe
\starttext
% An extra page. \page[yes]
\dorecurse{4}{
\placefigure[]{caption}{\externalfigure[cow.pdf][width=30pc]}\page}
\stoptext

Thanks! The \page after the figure certainly seems to fix it.
Unfortunately a page break after every figure is impractical in my
real document, but this might put me on the track of a solution (once
I've read the layout manual a couple more times).

I 've put \page just to show quickly the effect, but maybe there are
still problems

\setuplayout[location=doublesided,width=20pc]
\setuppagenumbering[alternative=doublesided,location={margin,header}]
\setupfloat[figure][location=inner]
\showframe
\starttext
% An extra page. \page[yes]
\dorecurse{40}{
\placefigure[here]{caption}{\externalfigure[cow.pdf][width=30pc]}}
\stoptext

Yes, that's pretty bad... in subsequent tests I've found that
‘diluting’ the figures with sufficient text (like adding \page) fixes
the problem -- unfortunately mixing [here] and [page] placement (as I
need to do in my document) messes it up again. In addition, several of
my tests crash ConTeXt with the error ‘Argument of \rootfloatparameter
has an extra }’, for example:

\setuplayout[location=doublesided]
\setuppagenumbering[alternative=doublesided,location={margin,header}]
\setupfloat[figure][location=inner]
\showframe
\starttext
\input knuth
\dorecurse{4}{
\placefigure[here]{caption}{\externalfigure[cow.pdf][width=17cm]}
\input knuth
\placefigure[page]{caption}{\externalfigure[cow.pdf][width=17cm]}
\input knuth
% \input knuth % uncomment this line to make the file work
}
\stoptext

Again, this works with v2011.02.25 (although figure numbers are mixed
up).

I think I'll have to give up on this now and revert to the old version,
but I'll put a pointer to this thread on the Wiki in case anyone else
runs into similar problems.

Should be fixed in the next beta.

Many thanks! I confirm that my original example works as expected with
ConTeXt 2011.10.01. However, for certain files (including my
dissertation) ConTeXt stops with the error ‘Argument of
\rootfloatparameter has an extra }’. Here's a minimal example which
causes the problem:

\starttext
\dorecurse{3}{
\placefigure[]{}{\externalfigure[cow.pdf]}
\input knuth
\placefigure[]{}{\externalfigure[cow.pdf]}
}
\stoptext

The example works if I comment out any of the three lines in the
\dorecurse, or if I change \dorecurse{3} to \dorecurse{2}. The example
also fails with 2011.09.20, but works with 2011.02.25.

Thank you once more; this now works as expected for me, both on the
example and on my dissertation.
