Graphics, Figures & Tables ⇒ Graphical size (drawing long line at the baseline of a word)

[karlisrepsons]

All,
perhaps someone of you might suggest how to get a long line and a word on it so that chars like 'a' are above that line, but 'p' or 'ņ' are split? I got the following code to do almost what was intended, but it has a problem with incorrect spacing and if similar construct is used within a tabu environment (possibly elsewhere too), strange problems appear:

Code: Select all

I was thinking to me: "How good it would be, had LaTeX a way to measure the graphical dimensions of some contents not counting any surrounding whitespaces..." Are things bad enough for LaTeX users not to have an exact width, height and depth of, say, a character like 'ļ'?

[Stefan Kottwitz]

Hi,

you could use \settowidth.

I could? Well yes, take a look how mightily bad it all works:

I had a look at the output. Whatever you are doing...

If I just write, let's say

Code: Select all

1
\color{myred}\rule{1pt}{\heightB}\rlap{\rule{\widthB}{1pt}}\usebox{#1}

I get the attached output, which looks meaningful.

Hmm, looks better now: with your idea I made another test, which can produce the following picture...

this look fine...

ok.jpeg (11.64 KiB) Viewed 3881 times

not precisely for width, but close...

Ā reg.jpeg (7.32 KiB) Viewed 3881 times

If italic is used, the situation gets worse however (!zoom problem in effect!):

not so good at all...

Also I didn't realize that my PDF viewer doesn't show correctly while not zoomed close enough (Adobe Acrobat 9, well)...

This could be produced with the following code:

So the question is in part still valid: can I get exact dimensions of some (whatever) element (glyph, table, picture etc), meaning the visible width, height and depth?

[Stefan Kottwitz]

With the mentioned commands you get the size of the box, not the size of the area which might be touched by the box contents. Commands such as \rlap, \llap and \smash change the box but not the contents. Hard to measure a box later if anything inside could have happened.

For typesetting usually the box matters - not if there's something overlapping because of italic or slanted font or because of kerning. The next letter follows the box. Here's the italic example showing what I mean.

Just to explain what \settowidth and \settoheight are expected to do. That's not a solution for measuring the area where ink gets on the paper.
