fake feature “extend” behaving weirdly
Hi Hans, this got posted on the DANTE list today. \definefontfeature [quite_wide] [extend=1.5] \definefont [mainfont] [file:Iwona-Regular.otf] \definefont [widefont] [file:Iwona-Regular.otf*quite_wide] \starttext \mainfont {\widefont foo} %% comment this line and “bar” is fine bar {\widefont baz} \stoptext The example defines two fonts with the same base font. If the scaled variant is used before the regular one then the latter will appear scaled as well and the spacing (bboxes?) gets messed up. I suspect a relation to this old issue: http://tracker.luatex.org/view.php?id=829 but if I substitute “slant” for “extend” the behavior is different. Best, Philipp

indeed a known bug in the backend that will be resolved once that part of the code has been cleaned up (extend etc is a seldom used hack so has a low priority) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Ah, so it’s the same bug. Thanks for clarifying! Philipp
