Dear gang, Given a set body font and text, how does one replace all characters of that font in that text with the corresponding rectangular bounding boxes? Once an answer to the above is spelled out: How does one control the width of the lines which make up the bounding boxes?

% \showglyphs

or

\definefontfeature[default][default][boundingbox=yes]

\starttext \input sapolsky \stoptext

Many thanks, Hans:

a - Toggling \showglyphs does not have any effect.

b - Is there a way to make the glyphs disappear and show only the boxes?*****

c- Is there a way to make the boxes frames instead backgrounds?

*****\start|stopcolor[white] doesn't work when boundingbox is yes. Well, it's a tracing option so don't expect miracles and integration with other features (like color). I'll add things like

\definefontfeature[default][default][boundingbox=yes] \definefontfeature[default][default][boundingbox=background] \definefontfeature[default][default][boundingbox=frame] \definefontfeature[default][default][boundingbox={background,empty}] \definefontfeature[default][default][boundingbox={frame,empty}] \definefontfeature[default][default][boundingbox={frame,red,empty}] as additional (probably never used) featurecreep but for sure will forget to document it etc etc 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 -----------------------------------------------------------------
