Lower case title with tikzposter package

Question

I'm new at using tikzposter and would like my poster title to be all lower case except for the first letter of the first word. Something like this:

"Work-in-progress poster title" instead of "WORK-IN-PROGRESS POSTER TITLE"

I have tried using these commands without success:

 \MakeLowercase{} 
 \lowercase{}
 \MakeTextLowercase{} (with the textcase package)

Any ideas?

Answer 1

The tikzposter class does

\gdef\TP@maketitle{
    \centering
    \vbox{
    \@titlegraphic
        \\[\TP@titlegraphictotitledistance]
        \centering
        \color{titlefgcolor}
        {\bfseries \Huge \sc \@title \par}
        \vspace*{1em}
        {\huge \@author \par}
        \vspace*{1em}
        {\LARGE \@institute}
    }
}

By the way, the class does \usepackage{ae}, which is very silly. Using \sc is sillier.

Anyway, taking the example file as a template,

\documentclass[
  25pt,
  a0paper,
  portrait,
  margin=0mm,
  innermargin=15mm,
  blockverticalspace=15mm,
  colspace=15mm,
  subcolspace=8mm
]{tikzposter} %Default values for poster format options.

 \tikzposterlatexaffectionproofon %shows small comment on how the poster was made at bottom of poster

%%% Added for avoding small caps in the title
\usepackage{etoolbox}
\makeatletter
\patchcmd{\TP@maketitle}
  {\bfseries \Huge \sc}
  {\bfseries\Huge}
  {}{}
\makeatother

%%% added for using a good font
\usepackage{lmodern}
\usepackage{amsmath}
\usepackage{substitutefont}
\substitutefont{OMX}{lmex}{cmex}

% Commands
\newcommand{\bs}{\textbackslash}   % backslash
\newcommand{\cmd}[1]{{\bfseries\color{red}#1}}   % highlights command

% Title, Author, Institute
\title{Using tikzposter}
\author{Pascal Richter, Elena Botoeva, Richard Barnard, \& Dirk Surmann}
\institute{}

% -- PREDEFINED THEMES ---------------------- %
% Choose LAYOUT:  Default, Basic, Rays, Simple, Envelope, Wave, Board, Autumn, Desert,
\usetheme{Autumn}
\usecolorstyle[colorPalette=BrownBlueOrange]{Germany}

\begin{document}

\maketitle

% omitted the rest

\end{document}

Answer 2

Works regardless of initial case

EDITED for tikzposter. The addition of \upshape was required to nullify the small caps:

\documentclass{tikzposter}
\newcommand\capone[1]{\caponehelp#1\relax}
\def\caponehelp#1#2\relax{\upshape\uppercase{#1}\lowercase{#2}}
\title{
\capone{work-in-progress}
vs.
\capone{WORK-IN-PROGRESS}
}
\begin{document}
\maketitle
\end{document}

Here with article

\documentclass{article}
\newcommand\capone[1]{\caponehelp#1\relax}
\def\caponehelp#1#2\relax{\uppercase{#1}\lowercase{#2}}

\begin{document}
\capone{work-in-progress poster title}

\capone{WORK-IN-PROGRESS POSTER TITLE}
\end{document}

Answer 3

\documentclass{tikzposter}

\makeatletter
\gdef\TP@maketitle{
    \centering
    \vbox{
    \@titlegraphic
        \\[\TP@titlegraphictotitledistance]
        \centering
        \color{titlefgcolor}
        {\bfseries \Huge \@title \par} % <-- removed \sc
        \vspace*{1em}
        {\huge \@author \par}
        \vspace*{1em}
        {\LARGE \@institute}
    }
}
\makeatother


\title{Work in progress}

\begin{document}

\maketitle


\end{document}
