let me put it this way: if there was an official way of doing what you want, a package like showframe would have support for it---but I don't see it.
Of course, you could fiddle around with
\parshape
, like
Code: Select all
\documentclass{scrartcl}
\usepackage[english]{babel}
\usepackage[T1]{fontenc}
\usepackage{blindtext}
\usepackage{wallpaper}
\usepackage[left=1.6cm, top=2.54cm, bottom=8.35cm, right=1.6cm, ignoreheadfoot]{geometry}
\usepackage{showframe}
\newlength\ia
\newlength\ib
\newlength\ic
\newlength\id
\newlength\la
\newlength\lb
\newlength\lc
\newlength\ld
\AtBeginDocument{%
\setlength\ia{378.422pt}% indent first area
\setlength\la{\linewidth}%
\addtolength\la{-\ia}% text length first area
\setlength\ib{90.2pt}% indent second area
\setlength\ic{\ib}% indent third area
\setlength\id{0pt}% indent fourth area
\setlength\lb{\linewidth}%
\addtolength\lb{-\ib}% 2nd text length
\setlength\lc{300pt}%
\setlength\ld{\lc}% 4th text length
\addtolength\lc{-\ic}% 3rd text length
\parshape=23 \ia \la \ia \la \ia \la \ia \la \ia \la \ia \la \ia \la \ia \la \ib \lb \ib \lb \ib \lb \ib \lb \ib \lb \ib \lb \ib \lb \ib \lb \ib \lb \ib \lb \ic \lc \ic \lc \ic \lc \ic \lc \id \ld
}
\CenterWallPaper{1}{page}
\begin{document}
\noindent\blindtext[3]
But look what happens, if you introduce a paragraph break (the empty line in the code just above this text)\ldots
\end{document}
but this approach would only work within a
single paragraph: any paragraph break would also break the
\parshape
command, as demonstrated above.
If you wish to pursue this further, you'd have to decide between `redefining
\par
'---IMHO not a good idea to begin with---and `reestablishing the wanted layout after a possible paragraph break' (where, say,
\everypar
might come in handy).
What's more, you'd have to take care about page breaks, too, otherwise the
\parshape
's current instruction would carry over to the beginning of the next page...
If you really want a page layout like this, you're probably better off using a DTP program.
