vertically centered aligment of different sized texts

vertically centered aligment of different sized texts

[frantisek holop]

hi there,

another question to which shamefully i cannot find the answer.
perhaps it's just too late...


consider the following example:


\definefont[BigFont][Regular sa 3]
\starttext
{\tfc The {\BigFont 7}\high{th} Seal}
\stoptext


how can i make that line vertically centered, like
    --,
the  /th seal
    /

:)


is \startalignment used for this?

I do not know if this is the best way to do this, but you can exploit 
inframed.

{\tfc The \inframed[foregroundstyle=\BigFont,frame=off]{ 7}\high{th} Seal}
or
{\tfc The \inframed[foregroundstyle=\BigFont,frame=off]{ 7\high{th}} Seal}

depending on what you want.

I think that startalignment is only for horizontal alignment, but I 
may be wrong here.

Hi,

Vertical positioning requires a \strut as an anchor. Hereafter you might 
use \vfill .... \vfill

\starttext
    \strut
    \vfill
        Your Text
    \vfill
\stoptext

Abusing math mode is easiest:

   \def\vcentered#1%
     {\dontleavehmode\mathematics{\vcenter{\hbox{#1}}}}
   \starttext
   {\tfc The \vcentered{{\BigFont 7}\high{th}} Seal}
   \stoptext

thanks a lot.
but if this is the "easiest" then what is the hardest? :)

i certainly envy the html/css people here.
some things are just much more easier.
of course, don't get me wrong, with less
powerful constructs come the limitations.

The mathematical center of the line is not necesarily the
optical center, so a somewhat more correct approach would
put all the stuff in an \hbox and then compute manually
how far it has to drop down.

For a more pleasing look, it would perhaps be even better
to line up a normal '7' as if it was an oldstyle numeral,
and then enlarging it while keeping the same vertical
alignment ratio.

Cheers, Taco

i haven't used latex for quite some time now, so i can't
recall how problematic it was to accomplish something like this,
but i find it interesting that there is no easy approach to this.

i've tried the old style numeral but i didn't like it.
by "keeping the same vertical alignment ratio" do you
mean something like \raise?

there probably is, so can you describe your problem in more detail?

when i tried to explain it, i found out that i lack a lot
of printing jargon :)

so here's just a link for a pdf which
uses Taco's mathmode vcentered macro.

http://obiit.org/minusf/tex/7th-seal.pdf
http://obiit.org/minusf/tex/7th-seal.tex


basically it's just having different sized
fonts aligned based on the bigest one, vertically centered

taco's solution is pretty clean and texie; (btw, in supp-box you can 
find many boxing macros, but it's hard to keep an overview of what is 
needed and provided since each situation differs)

Take the 'normal' 7 in the 'normal' tf size, but place it
as if it was an old-style numeral (using something like 
\lower2pt\hbox{7}). Measure the height of the result box.
Now you have a  box that is say 4.5pt above (and 2pt below
the baseline). Create a new box with the 7 in the increased
font size, and use \lower to make sure that 4.5/6 of it is
above the baseline.  You asked for 'complicated', right?

i think this is something else.  this centers the line in some context,
but not the contents of the line if the line contains fonts in different
sizes.

i used to use this construct even in latex, very good for title pages,
but intead of \strut i just put a used a non breakable space: ~

1 + 2 = 3; therefore, 4 + 5 = 6.
