Hi,

How do you get a uniform line spacing in the following frames where it's not
the case ?

\setuplayout[header=0pt,footer=0pt]

\def\myFrameSetupA{\setupframed[width=\textwidth,frame=on,top=\vss,bottom=\vss,align=middle]}
\def\myFrameSetupB{\setupframed[width=\textwidth,frame=on,location=middle,align=middle,offset=15pt]}

\def\myFrameTextA{Text\\In A\\Frame}
\def\myFrameTextB{Text\blank[medium]In A\blank[medium]Frame}

\def\myFrameA{\framed[height=50mm]{\bf\myFrameTextA}}
\def\myFrameB{\framed[height=50mm]{\bf\myFrameTextB}}
\def\myFrameC{\framed[height=50mm]{\switchtobodyfont[35pt]\bf\myFrameTextA}}
\def\myFrameD{\framed[height=50mm]{\switchtobodyfont[35pt]\bf\myFrameTextB}}

\def\myFrameOne{\myFrameSetupA\myFrameA}  % OK
\def\myFrameTwo{\myFrameSetupA\myFrameB}   % OK
\def\myFrameThree{\myFrameSetupA\myFrameC}  % line spacing is not uniform
\def\myFrameFour{\myFrameSetupA\myFrameD}  % line spacing is not uniform

\def\myFrameFive{\myFrameSetupB\myFrameA}  % OK
\def\myFrameSix{\myFrameSetupB\myFrameB}   % OK
\def\myFrameSeven{\myFrameSetupB\myFrameC} % line spacing is not uniform
\def\myFrameEight{\myFrameSetupB\myFrameD}  % line spacing is not uniform

\starttext
 \myFrameOne
 \blank
 \myFrameTwo
 \blank
 \myFrameThree
 \blank
 \myFrameFour

 \page

 \myFrameFive
 \blank
 \myFrameSix
 \blank
 \myFrameSeven

\stoptext

Add a \par after the last line.

\def\myFrameTextA{Text\\In A\\Frame\par}
\def\myFrameTextB{Text\blank[medium]In A\blank[medium]Frame\par}

Re: files in attachment

Why is the (local) interline space (set to 30pt or 2ex) so small compared to
the frame's local (switched to 38pt) bodyfont ?

At first I thought it was related to \setupbodyfont but \setupbodyfont[38pt]
doesn't make a difference.

How do you get the (local) interline spacing (pt or ex) in proportion to the
local (switched to) bodyfont ?

You're funny, as you can see in my example below your text alone has
a height of 26.18pt and you set a line distance of 30pt.

\starttext

\setbox\scratchbox\hbox{\switchtobodyfont[38pt]Text In A Frame}

\the\htdp\scratchbox

\stoptext

What do you expect? TeX does only what you tell him but you get
a better result with a bigger line distance, the default value from
ConTeXt is 2.8ex.

What do you not understand in my example?

The 26.18pt are only the height of the sample text, not each character
has the height of the font size which includes the height and depth.

You can see here the output is correct and only characters with large
height and depth match the given fontsize.

\starttext
\setbox\scratchbox\hbox{\switchtobodyfont[38pt](}
\the\htdp\scratchbox % 37.45pt
\stoptext

I show you in another example why you value for the interlinespace
is to small for characters with depth.

\starttext

\vbox
   {\switchtobodyfont[38pt]
    \setupinterlinespace[line=30pt]
    \lineskiplimit-\maxdimen
    Big text\crlf written in\crlf three rows\par}

\stoptext

Thanks a lot for the clarification Wolfgang.

I guess I was still playing with this kind of major flawed thinking coming
from WYSIWYG wordprocessors where isn't concerned thinking about these
technical aspects (what's underneath), instead type/edit as characters
appear on screen in real time, then when switching to typesetting systems
extrapolate and expect things to work in the same way.

I'll digg into the manuals' corresponding chapters to get more familiar
with these technicalities and let them sink in.

Alan

Indeed, I goofed big time...

It was most useful to refresh my (lack of) understanding about how
TeX's interline spacing works. <grin>
