I want to prepare view of LCD display that can have 8 lines of big text or 16 lines of small text. The sizes may be mixed so some lines will be with small font while some with big font at once.
Unfortunately strange things happen with distance between lines. What am I doing wrong?
Code
\documentclass{article}
\newcommand{\fontsmall}{\fontsize{5pt}{6pt}\selectfont}
\newcommand{\fontnormal}{\fontsize{10pt}{12pt}\selectfont}
\newsavebox{\mybox}
\newenvironment{display}{%
\fontnormal%
\begin{lrbox}{\mybox}%
\begin{minipage}[][8\baselineskip][t]{15\baselineskip}%
}{%
\end{minipage}%
\end{lrbox}\fbox{\usebox{\mybox}}
}
\begin{document}
\begin{display}%
linie 1\\
linie 2\\
linie 3\\
linie 4\\
linie 5\\
linie 6\\
linie 7\\
linie 8
\end{display}%
\begin{display}%

The problem is that you are misusing
\\for line breaks. Changes to the line spread will only take affect if the text in question is ended with a new paragraph. This can be done by leaving an empty line or use\par.
