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

Hi, it's my first message on this list. I've searched in ConTeXt manuals, TeX.SX and here, but couldn't find a way to achieve these 4 requirements altogether:

• Place a figure as full-page figure • Change orientation accordingly (if it's a landscape PDF, for instance) • Make that using \setupfloat (or other setup), not directly in \placefloat • Place captions in another page (ideally on opposite page) Problems: • I can't get # 1 and # 3 at same time • \setupfloat doesn't have before option, which I could use to change orientation • I have no idea how to accomplish # 4 A minimal working example (PDF in attachment):

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \definepapersize[default][A4, portrait] \definelayout[default][topspace=0.6cm, topdistance=0cm, header=1cm, headerdistance=0cm, height=27.3cm, footer=0cm, backspace=4.2cm, width=13.6cm] \setuppapersize[default] \setuplayout[default] \setuppagenumbering[alternative=doublesided, location={header}] \setupexternalfigures[location={default}]

\definepapersize[rotate][A4, landscape] \definefloat[bigfigure][bigfigures][figure] \setupfloat[bigfigure][default={page}, width=1\textwidth, height=1\textheight, before={\setuppapersize[rotate]}] % there's no before in setupfloat \setupcaption[bigfigure][location={opposite}] % there's no opposite location in setupcaption

\starttext \showframe \dorecurse{2}{\input{knuth}}

\setuppapersize[rotate] % this doesn't work because is in same page \startplacebigfigure[title={A cow}]{\externalfigure[cow]}\stopplacebigfigure \setuppapersize[default]

\dorecurse{2}{\input{knuth}} \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
