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}

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

[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. \starteffect is kind of old (comes from mkii), but you could use the

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 -----------------------------------------------------------------
