Uau! Thanks a lot for a very nice hint. So you can make something like that:
-------------------------------------------------- \setupcolors[state=start] \starttext \setupMPvariables[CircleSomething][dimension={(100,100)},center={(50,50)},r=10] \startuseMPgraphic{CircleSomething} pair dimension, center; % TODO: this also has to be passed as parameter!!! % now it stands for: width=10cm scale := 10cm/(xpart \MPvar{dimension}); picture bboxpicture; dimension := \MPvar{dimension} scaled scale; center := \MPvar{center} scaled scale; r := \MPvar{r}*scale; pickup pencircle scaled 2pt; % proper bounding box fill unitsquare xyscaled dimension; bboxpicture := currentpicture; currentpicture := nullpicture; draw fullcircle scaled (2*r) shifted center withcolor red; setbounds currentpicture to boundingbox bboxpicture; \stopuseMPgraphic \defineoverlay[CircleBlueTulip][\uniqueMPgraphic{CircleSomething}{dimension={(400,460)},center={(222,460-330)},r=25}] \defineoverlay[CircleRedTulip][\useMPgraphic{CircleSomething}{dimension={(400,460)},center={(148,460-330)},r=25}] \framed[background={foreground,CircleBlueTulip},offset=0pt,strut=no]{\externalfigure[Kochloewe_c][width=10cm]} \framed[background={foreground,CircleRedTulip},offset=0pt,strut=no]{\externalfigure[Kochloewe_c][width=10cm]} \stoptext -------------------------------------------------- So, do you get any real output (besides the image)? I cannot see any circles in the pdf. ConTeXt ver: 2005.06.07 fmt: 2005.6.7 int: english mes: english Patrick -- ConTeXt wiki and more: http://contextgarden.net
