[...] Everthing is fine when italic fonts aren’t used.
It can be fixed with a strut option for lists, e.g. \setuplist[strut=no]. The problem in this case is that the ex-height for the italic font is larger than the ex-height for the upright font which pushes the text down because add a strut at the begin and end of the entries.
Many thanks for your reply, Wolfgang.
I don’t get \setuplist[strut=no] working in the minimal sample I sent yesterday.
The key isn't supported yet but it could help to avoid the spacing problem.
Below is a minimal example of the problem, the \setstrut setting changes the height of the strut for the italic font.
I must admit that I don’t understand how to handle struts (I’m not sure I understand what they actually are.)
The simple answer is that a strut is a invisible vertical line with the height and depth of a line. When you look at the example below you can see the text in the first box touches the top and bottom boundaries.
When we add a strut at the begin and end of the text we ensure the last line has the depth of a normal line and the first line gets the complete height of a line.
%%%% begin example \starttext
\ruledvbox{\samplefile{weisman}}
\blank
\ruledvbox{\begstrut\samplefile{weisman}\endstrut}
\stoptext %%%% end example
Most fonts (I checked only a small number) don't have such a big difference between the ex-height of the upright and italic styles which makes it hard to notice the problem.
Yesterday I realized that Pagella was an extreme case, because I tried to report this issue before, but Latin Modern didn’t show the issue (so I thought I was doing something wrong).
Yes, pagella is a extreme case but when you use bold text the vertical spacing is also messed up. You can avoid this when you use a fixed lineheight (e.g. \setupinterlinespace[line=14pt]) because the default distance is font dependant (default: 2.8 * ex-height). or one can play with these parameters, that default to:
\setupinterlinespace [height=.72, depth=.28] (maybe we should have recomended values for specific fonts) 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 -----------------------------------------------------------------
