Hello,

I'm looking to rotate an externalfigure inside of its bounding box in increments of 90 deg. Its real easy with 0 and 180, you can just do:

\externalfigure[blah.pdf][width=5.0in, height=2.0in] \rotate[rotation=180]{\externalfigure[blah.pdf][width=5.0in, height=2.0in]}

Both commands result with an image that is 5.0in wide and 2.0in tall.

But the problem comes when rotating a externalfigure at 90 and 270 degrees (or more generally, anything besides 0 and 180). The rotation is applied to the whole bounding box instead of rotating the picture within a bounding box. The following images will be rendered 2.0in wide and 5.0in tall.

\rotate[rotation=90]{\externalfigure[blah.pdf][width=5.0in, height=2.0in]} \rotate[rotation=270]{\externalfigure[blah.pdf][width=5.0in, height=2.0in]}

Are there any plans to add support for specify an externalfigure's rotation within its bounding box, similar to this: \externalfigure[blah.pdf][width=5.0in, height=2.0in, rotation=90]

Cheers, Mike

Hi Mike, you can control the rotation placement with the location key and the value middle for location seems to be what you want but the the result looks to me weird or broken and tried to fix this with the new value center, you can see the results in small example below. \unprotect \def\dodorotatenextbox#1#2% quite some trial and error -) {\dontshowcomposition \dontcomplain \ifnum#2=\plusfour % new, location=middle \!!widthb \nextboxwd \!!heightb\nextboxht \!!depthb \nextboxdp \setbox\nextbox\vbox{\vskip.5\nextboxht\hskip-.5\nextboxwd \flushnextbox}% \smashbox\nextbox \else\ifnum#2=\plusfive % wolf: location=center \!!widthb \nextboxwd \!!heightb\nextboxht \!!depthb \nextboxdp \setbox\nextbox\vbox{\vskip.5\nextboxht\hskip-.5\nextboxwd \flushnextbox}% \smashbox\nextbox \fi\fi \!!widtha \nextboxwd \!!heighta\nextboxht \!!deptha \nextboxdp \!!doneafalse \!!donebfalse \ifcase#2\or % 1: fit \or % 2: depth, not fit \!!doneatrue \!!donebtrue \or % 3: depth, fit \!!donebtrue \fi \setbox\nextbox\vbox{\hbox{\raise\nextboxdp\flushnextbox}}% \!!dimena \nextboxht \calculatecos\@@rorotation\edef\cos{\calculatedcos\@@rorotation}% \calculatesin\@@rorotation\edef\sin{\calculatedsin\@@rorotation}% \@@layerxpos\zeropoint \@@layerypos\zeropoint \@@layerxoff\zeropoint \@@layeryoff\zeropoint \ifdim\sin\points>\zeropoint \ifdim\cos\points>\zeropoint \@@layerxsiz \cos\!!widtha \@@layerysiz \sin\!!widtha \advance\@@layerxsiz \sin\!!dimena \advance\@@layerysiz \cos\!!dimena \@@layerypos \cos\!!dimena \if!!donea \@@layerxoff \negated\sin\!!dimena \advance\@@layerxoff \sin\!!deptha \fi \if!!doneb \@@layeryoff \cos\!!deptha \fi \dododorotatenextbox \else \@@layerxsiz \negated\cos\!!widtha \@@layerysiz \sin\!!widtha \advance\@@layerxsiz \sin\!!dimena \advance\@@layerysiz \negated\cos\!!dimena \@@layerxpos \negated\cos\!!widtha \if!!donea \@@layerxoff -\@@layerxsiz \advance\@@layerxoff \sin\!!deptha \fi \if!!doneb \@@layeryoff \negated\cos\!!heighta \fi \dododorotatenextbox \wd\nextbox\if!!donea\sin\!!deptha\else\@@layerxsiz\fi \fi \else \ifdim\cos\points<\zeropoint \@@layerxsiz \negated\cos\!!widtha \@@layerysiz \negated\sin\!!widtha \advance\@@layerxsiz \negated\sin\!!dimena \advance\@@layerysiz \negated\cos\!!dimena \@@layerxpos \@@layerxsiz \@@layerypos \negated\sin\!!widtha \if!!donea \@@layerxoff -\@@layerxsiz \advance\@@layerxoff \negated\sin\!!heighta \fi \if!!doneb \@@layeryoff \@@layerysiz \advance\@@layeryoff \cos\!!deptha \fi \dododorotatenextbox \wd\nextbox\if!!donea\negated\sin\!!heighta\else\@@layerxsiz\fi \else \@@layerxsiz \cos\!!widtha \@@layerysiz \negated\sin\!!widtha \advance\@@layerxsiz \negated\sin\!!dimena \advance\@@layerysiz \cos\!!dimena \ifdim\sin\points=\zeropoint \@@layerxpos \zeropoint \@@layerxoff \zeropoint \@@layerypos \@@layerysiz \if!!doneb \@@layeryoff \!!deptha \fi \else \@@layerypos \@@layerysiz \@@layerxpos \negated\sin\!!dimena \if!!donea \@@layerxoff -\@@layerxsiz \advance\@@layerxoff \negated\sin\!!heighta \fi \if!!doneb \@@layeryoff \negated\sin\!!deptha \fi \fi \dododorotatenextbox \ifdim\sin\points=\zeropoint \else \wd\nextbox\if!!donea\negated\sin\!!heighta\else\@@layerxsiz\fi \fi \fi \fi % new, location=middle \ifnum#2=\plusfour \setbox\nextbox\vbox{\vskip-.5\!!heightb\hskip.5\!!heightb \flushnextbox}% \nextboxwd\!!widthb \nextboxht\!!heightb \nextboxdp\!!depthb \else\ifnum#2=\plusfive % wolf: location=center \setbox\nextbox\vbox{\vskip.5\!!heightb\ifnum#1=270\relax\hskip2\!! heightb\fi\flushnextbox}% \nextboxwd\!!widthb \nextboxht\!!heightb \nextboxdp\!!depthb \fi\fi} \def\complexrotate[#1]% framed met diepte ! {\getparameters[\??ro][#1]% \processaction [\@@rolocation] [ \v!depth=>\!!counta\plusthree\donefalse,% depth fit - raw box \v!fit=>\!!counta\plustwo \donefalse,% depth tight - raw box \v!broad=>\!!counta\plusone \donefalse,% nodepth fit - raw box \v!high=>\!!counta\plusone \donetrue ,% nodepth fit - framed \v!middle=>\!!counta\plusfour \donefalse,% centered, keep dimensions \v!center=>\!!counta\plusfive \donefalse,% \s!default=>\!!counta\plusthree\donetrue ,% depth fit - framed \s!unknown=>\!!counta\plusthree\donetrue ]% depth fit - framed \ifdone \def\docommand{\localframed[\??ro][#1,\c!location=]}% \else \let\docommand\relax \fi \dowithnextbox{\dorotatenextbox\@@rorotation\!!counta\egroup}\vbox \docommand} \protect \setuppapersize[A4,landscape][A4,landscape] \starttext \input knuth \rotate[rotation=0]{\framed[width=4cm,height=2cm,align={middle,lohi}] {Text}} text \rotate[rotation=90,location=center]{\framed [width=4cm,height=2cm,align={middle,lohi}]{Text}} text \rotate [rotation=180]{\framed[width=4cm,height=2cm,align={middle,lohi}]{Text}} text \rotate[rotation=270,location=center]{\framed [width=4cm,height=2cm,align={middle,lohi}]{Text}} text %\rotate [rotation=270]{\framed[width=4cm,height=2cm,align={middle,lohi}]{Text}} \input knuth \stoptext Wolfgang
