feature request: clipping option for externalfigure
Hello, I would like to clip an external eps-figure as LaTeX does with the clip option. Please consider the attachment as an example for en eps with white border and the following LaTeX and ConTeXt code: \starttext % no clipping possible here bla bla bla bla bla bla bla bla bla bla bla bla \externalfigure[test-img][width=0.5\textwidth] bla bla bla bla bla bla bla bla bla bla bla bla \stoptext \documentclass{article} \usepackage{graphicx} \begin{document} % here the white border is clipped away bla bla bla bla bla bla bla bla bla bla bla bla \includegraphics[clip,width=0.5\textwidth]{test-img} bla bla bla bla bla bla bla bla bla bla bla bla \end{document} Or is there already such (undocumented) feature? Cheers, Peter -- http://pmrb.free.fr/contact/

Please browse through core-fig.tex. Around line 2100 there is documentation for the \clip and \setiupclipping commands. Cheers, taco

Thanks! I tried different options (x=1,y=1 or width=0.5\textwidth etc) but whenever I use \clip[...]{\externalfigure...} the figure disappears. What options should I use, to clip just exactly to the bounding-box (as the LaTeX clip-option)? Cheers, Peter -- http://pmrb.free.fr/contact/

Peter was asking for something different, I believe. \clip do the thing well but you have to measure a bb somewhere, e.g. in GhostView. Since \externalfigure have to know bb then an option 'clip' can do that without manual measuring. There might be even en extension: apart from 'clip' option there could also be 'bb=10 20 100 200' option for overwritting original boundingbox. Clipping a figures would be a bit more strightforward.

i dunno what the intended effect is but here's an example \starttext \startuseMPgraphic{test} draw fullcircle scaled 4cm withpen pencircle scaled 1cm ; setbounds currentpicture to boundingbox fullcircle scaled 4cm ; \stopuseMPgraphic \ruledhbox{\useMPgraphic{test}} \vskip3cm \ruledhbox{\clip{\useMPgraphic{test}}} \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

\ruledhbox{\useMPgraphic{test}}
\vskip3cm
\ruledhbox{\clip{\useMPgraphic{test}}}
\stoptext
I see, I did not realize such simple usage of \clip (without options). That do exactly what was thinking about. One character of typing difference between: \clip{\externalfigure{test}} and \externalfigure[clip]{test} is not crutial:) So sorry for noise. But as far as I know, \clip works only with left|top,width|height params. Could right|bottom be added (assuming at least one from left-width-right and top-height-bottom is missing - if not width|height is ignored)? Or there is again some secret that I missed? Vit

Hello Hans, of course, I've already tried \clip{\externalfigure[...][...]} but the figure disappears completely. \clip{\useMPgraphic{test}} disappears too. And now I see: it works for PDF output, so there is probably just an error in the dvi driver. Cheers and thanks, Peter -- http://pmrb.free.fr/contact/

well, if you can find out what the problem is we can fix it (i dunno if it's in dvips or in the special driver of context; maybe something changes in dvips - which is probably only tested with latex -) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Probably I won't be able to find out the details, but I can make some tests. I can already say, that dvips and xdvi behave the same: only white area instead of the figure. Cheers, Peter -- http://pmrb.free.fr/contact/
