"externalfigure" vs. "draw externalfigure" in metafun
Dear Hans, I have problems with externalfigure inside metapost. In MKII, only externalfigure "something.png"; works, while in MKIV only draw externalfigure "something.png"; is accepted. Is there any chance to accept one of the syntaxes in both flavours? Thank you, Mojca Minimal example: \starttext \startMPpage % only good for MKII externalfigure "abc.png" xyscaled (5cm,8cm); % only good for MKIV % draw externalfigure "abc.png" xyscaled (5cm,8cm); \stopMPpage \stoptext

Hmm, I noticed that too. However I'm sure that plain "externalfigure" used to work in MkIV too, so I guess the change happened (more or less) recently. -- Best Regards, Andreas

Does the following workaround work for you? def mydraw text t = def f = begingroup t endgroup enddef; if picture f : draw f ; fi enddef; mydraw externalfigure "abc.png" xyscaled (5cm,8cm); Nicola

This may be better: def mydraw text t = _mydraw begingroup t endgroup enddef; def _mydraw primary f = if picture f : draw f ; fi enddef; mydraw externalfigure "abc.png" xyscaled (5cm,8cm); Nicola

If Hans is willing to fix metafun, I would prefer to avoid workarounds. (I don't care which syntax is used, but I would be grateful if the same syntax worked in both mkii and mkiv.) Since you seem to be a metapost expert: do you have any idea what exactly would have to be fixed in ConTeXt core code? If ConTeXt won't be fixed for whatever reason, I will write a wrapper function using your code, but I would like to avoid that. Hans? Mojca

is in "too busy mode" currently .. more later (but the metafun mkiv way is conceptually more ok so we might need to change metafun mkii) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Edit mp-spec.mp and change the line draw p withcolor ... with image(draw p withcolor ...) The line is in the body of the doexternalfigure macro. Then, 'draw externalfigure ...' should work in mkii, too. Note: knowledge of ConTeXt internals - which I don't have - is needed to be sure that the patch doesn't break anything. Hence, the above is to be considered as a wild guess of mine. Nicola
