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:
...
Does anyone have any ideas or insights?
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.
