Hi Hans,

I encountered an issue in fontsizing in math mode that I do not understand. Searched the manual but couldn't find (or missed) the clue.

Using the green presentation style but changed to a somewhat larger fontsize by adding: \setupbodyfont[lbr, sans, 17.3pt] % lucidabright

typesetting the following text: {abc$abc$abc} --- {\tfx abc$abc$abc} --- {\tfx abc}{$\tfx abc$}{\tfx abc}

In the first the abc's have the same size. In the second the math part has kept its size, the other two are smaller. In the third the math part is now so small is doesn't match in size as it did in the first.

I would have thought the math would vary in accordance with the \tfx. However, within $'s the font does not follow the outside \tfx, while inside a different size seems to be chosen. I am baffled. Can you point in the right direction? Thanks.

The x and xx sizes are meant for text purposes, like text super and subscripts and pseudo kaps; opposite to a-d sizes that are meant for heads and so; as a result, x and xx are fast, a-d are slower due to the fact that math is synchronzied (can be turned on/off) When you want to switch to a smaller/larger bodyfont, you should use \smallbodyfont == \switchtobodyfont[smallbodyfont] \bigbodyfont == ... This will switch the whole thing (kee pin mind that for math also the two smaller super/sub sizes have to be set up). When using typescripts (i.e. namespaces font sets with global file resolving) the penalty in terms of time is small. So: use \smallbidyfont instead of \tfx in your case btw, in the third example the second tfx is actually a tfxx, so {text \tfx text \tfx text} makes the last one real small; as said, the main reason for the x sizes in in super/sub scripts and pseudo kaps (we use those a lot in educ docs and these commands also obey the font style) Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE | pragma@wxs.nl Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------
