[MetaFun] Trying to understand outlinetext, 'stretch' effect and \kerncharacters

Dear list, I have the following graphic \startuseMPgraphic{TitleGraphic} draw outlinetext.b (\MPstring{TitleText}) (withcolor "titlefg") (withcolor "titleoutline"); \stopuseMPgraphic which I tried to use as follows to produce a stylized 'title' head: \setupMPtext{TitleText}{% \starteffect[stretch]\bfc\namedstructurevariable{title}{title}\stopeffect} \useMPgraphic{TitleGraphic} [colors "titlefg" and "titleoutline" are set using \definecolor] But, the 'stretch' effect caused by \starteffect[stretch]…\stopeffect does not work with 'outlinetext' method in the MPgraphic. I have verified that the desired effect is produced using 'textext' method instead. But in that case I have to cheat (i.e draw twice; once with blownup) to get the text outline. Now, if I write instead \setupMPtext{TitleText}{% \kerncharacters[0.15]\bfc\namedstructurevariable{title}{title}} \useMPgraphic{TitleGraphic} then the desired effect is produced. As such, my purpose is served well by using \kerncharacters. Nonetheless, I request your kind help in understanding why this is happening and/or if I am doing something wrong. Thanks, kauśika

Please read '\setupMPtext' as '\setMPtext' in the above. Apologies for the typos. kauśika

low level pdf magic ... so not done in mp

tex magic so done in tex pseudo font feature effect in mkiv / lmtx which then makes a real font instance instead of mixing in some pdf magic Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
