Hi,
in documentations I can find various examples of circled text. But copying them I had no success till now.
I want to place text in half circles of various radiuses. Is there anywhere a simple example?
The Metafun experts would probably tear this apart...
\startuniqueMPgraphic{half circle} path p, q ; p := fullcircle scaled OverlayWidth; q := (p cutafter (point .5 along p)) shifted (0,-.5BodyFontSize) ; fill q -- cycle withcolor lightgray ; draw q withpen pencircle scaled 2pt withcolor darkred ; setbounds currentpicture to boundingbox p ; \stopuniqueMPgraphic
\defineoverlay[half circle][\uniqueMPgraphic{half circle}]
\starttext
\framed[background=half circle,frame=off]{Text width half circle.}
\stoptext
Well, if you really want a tear down ... \startuniqueMPgraphic{half circle} path p ; p := halfcircle scaled OverlayWidth shifted center OverlayBox ; path q ; q := p shifted (0,-StrutDepth) ; draw image ( fill q -- cycle withcolor OverlayColor ; draw q withcolor OverlayLineColor ; ) withpen pencircle scaled 2pt ; setbounds currentpicture to boundingbox OverlayBox ; \stopuniqueMPgraphic \defineoverlay[half circle][\uniqueMPgraphic{half circle}] \starttext \framed [background=half circle, frame=off, framecolor=red, backgroundcolor=lightgray] {Text width half circle.} \framed [background=half circle, frame=off, framecolor=red, backgroundcolor=lightgray] {Text width half circle and more.} \stoptext
My greatest problems seem to be in the embedding code.
