issue with logo and aalt

issue with logo and aalt

[Pablo Rodríguez]

Hi there,

the following minimal sample shows one problem I have when using all
small caps (all lowercase and small caps) in titles.

	\setuppapersize[A4,landscape]
	\setuppagenumbering[location=]
	\usemodule[simplefonts][size=200pt]
	\setmainfont[TeX Gyre Pagella]
	\definefontfeature[allcaps][default][aalt=yes]
	\starttext
	\TeX \addfs{allcaps} \TeX
	\stoptext

The logo in small caps has the letter E than in the all caps.

My question is how should I redefine the TeX logo so that the all small
caps version, i.e. that both logos have the letter E at the same height?
(Otherwise, the all small caps logo seems weird.)

Thanks for your help,


Pablo

A bit off topic, but aalt stands for "access all alternates" and just
lists all alternates of a given glyph with no semantics at all, and is
there for GUI apps that present a glyph pallet to allow users select
alternate shapes of any glyph (which can be anything), which is pretty
useless for TeX usage.

 Khaled

Thanks, I knew it, Khaled.

aalt is not the best way to do it, but I didn't know how to get old
style numbers, small caps and all lowercase texts. I cannot achieve it with:

    \definefontfeature[allcaps][default][onum=yes,smcp=yes]

And redefining the setuphead command for chapter:

    \setuphead[chapter][style=\tfb\addfs{allcaps},command=\lowercase]

doesn't do the work (and it breaks the centering in a more elaborate
command).

How could I do it?

Many thanks for your help,


Pablo

\setuphead[chapter][style=\WORD\tfb]

\starttext
\chapter{This was done with \CONTEXT!}
\stoptext

Thanks, Wolfgang, it fixed my ignorance.

I'm afraid I still have the problem reported before.

I have no idea on how the \TeX logo is defined, but the capital E in the
\TeX logo seems to be lowered by the x-height of the font.

This method is as successful as other fonts than Computer Modern have
the same ascender as Computer Modern itself. And it doesn't work with
all small cap letters, because these are defined by having no ascender,
that is, x-height and cap height is the same.

My question is how can I redefine the \TeX logo using the E actual cap
height, so that it is lowered in the same proportion using the standard
form and the all small caps form.

Thanks for your help,


Pablo
