Salve a tutti.
Ho lavorato al problema posto in questo thread e credo di essere arrivato ad una soluzione decente. Nel farlo ho ricevuto i consigli illuminanti di Claudio Beccari, che ringrazio. La soluzione che presento qui è senz’altro suscettibile di miglioramenti e modifiche future.
Premessa
Intanto, incollo un esempio di layout reale che mi interessa riprodurre:
Il problema in questione è uno di quelli che si risolve semplicemente con un impaginatore tipo Xquark, o simili altri programmi, cose professionali. Alternativamente si può provare con il freeware Scribus. Il mio scopo è di utilizzare LaTeX ed ho cercato una soluzione che non si servisse di strumenti “esterni”.
Soluzione
Ho creato l’ambiente:
`\longmedal[
ispirandomi al nome “medaglione” usato da Beccari nella guida a LaTeX distribuita da GuIT. L’ambiente longmedal si avvale del pacchetto xkeyval per il passaggio dei parametri. Un esempio è il seguente:
`
\definecolor{mylightgray}{rgb}{0.95,0.95,0.95}
%
\longmedal[%
width=1.1\textwidth, height=0.6\textheight,
topfraction=0.65,
innermargin=1.5cm,outermargin=0.2cm,
columns=1,
drawframe=true,drawsideframe=false,
framerule=2pt,frameheadrule=2.5em,framesep=2mm,
framecolor=darkgray,framebgcolor=mylightgray,
label={lmd:OneA}]%
{
Test testo testo testo …
}
`
Uno dei parametri più significativi è “height”: esso indica l’altezza complessiva del medaglione. Un altro parametro interessante è “columns”: ho voluto gestire anche un numero superiore a uno di colonne di testo avvalendomi del pacchetto multicols. Il significato degli altri parametri è intuitivo.
Incollo qui il risultato di due esempi di cui darò il codice più avanti:
esempio 1
esempio 2
L’algoritmo che divide il testo all’interno dell’ambiente e lo fa fluire nei diversi medaglioni è abbastanza semplice:
1. Si raccoglie tutto il “materiale”, cioè il testo, in una vbox.
2. Si comincia ad estrarre la parte alta della vbox con il comando
primitivo \vsplit di TeX di altezza prefissata (height).
3. Si utilizza un nuovo tipo di float (pacchetto float) con specificatore [t]
ed imponendo, tra le altre cose, topfraction=
topnumber = 1, bottomnumber=0, totalnumber=1.
4. Se l’altezza rimanente della vbox è ancora superiore a height
si riparte dal punto 2, altrimenti si applica il punto 3 alla vbox e
si finisce.
Per quanto riguarda l’altezza delle diverse scatole in cui è suddiviso il
testo ho scelto di adottare rigidamente un’altezza costante
e gestire il contenuto con delle \rule di LaTeX opportune
(si vedono passando l’opzione debug=true)
Per controllare la parità del numero di pagina ho usato il pacchetto
chngpage ( http://www.tex.ac.uk/cgi-bin/texfaq2html?label=oddpage ).
Codice
Allego il risultato del mio lavoro fino a questo punto.
