Hi,
This sounds quite complicated, really.
I am not at all sure how this page rotation should work but I assume you plan a
pdf-only document then? Otherwise, I would expect rotating the figure instead
of the whole page. Also, rotating the paper does not rotate the layout, at
least not if you use a fixed height and width. You would need something like
this for auto-resizing \textheight and \textwidth:
\definelayout[default][topspace=0.6cm, topdistance=0cm, header=1cm,
headerdistance=0cm,
height=fit, footer=0cm,
backspace=4.2cm, width=fit]
Another problem is that setting the width and height of a float does not affect
any externafigure side. You need to do a \setupexternalfigure for that.
And there is (afaik) no support for having a “two-page” float. The “opposite”
key is used to put the float (including caption) on the opposite side of the
current page.
But at least there is a command to typeset a caption standalone, so perhaps
that will help? You would then *not* use the \startplacebigfigure, but place
the caption and the image manually:
\page
\placefloatcaption[bigfigure][title={A cow}]
\page
\externalfigure[cow]
\page
Best wishes,
Taco
