Dear list,

I have the following sample:

\startluacode fonts.handlers.otf.addfeature { name = "gpos_test", type = "single", data = { [ '¿' ] = 1000, [ '¡' ] = 1000, } } \stopluacode \definefontfeature[ktest][gpost_tes=yes]

\starttext \startTEXpage[offset=1em] \feature[+][gpos_test] ¿? ¡! \stopTEXpage \stoptext

This tries to move vertically the opening question and exclamation marks, so they are at the same height that its closing counterparts.

I thought there may be a GPOS feature that could achieve this, but I must admit I have no idea about how to achive it.

In my document, this should only work with the slanted feature.

Could anyone tell me how could I move vertically single glyphs?

Many thanks for your help, typos

\definefontfeature[ktest][gpost_tes=yes] and wrong feature name \feature[+][gpos_test] so: \startluacode fonts.handlers.otf.addfeature { name = "gpos_test", type = "single", data = { [ '¿' ] = { 0, 400 }, [ '¡' ] = { 0, 400 }, } } \stopluacode \definefontfeature[ktest][gpos_test=yes] \starttext \startTEXpage[offset=1em] \ruledhbox{¿? xx ¡!} \addfeature{ktest} \ruledhbox{¿? xx ¡!} \stopTEXpage \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
