Create a document class based on a KOMA-Script class: paper size problem

Question

I want to create a document class based on a KOMA-Script class. First I would like change paper size, which would be defined in cls file. I see that similar problem was questioned in here, but without clear solution. Has anyone of you an example of own document class based on a scrbook?

wikibook.cls:

\ProvidesClass{wikibook}[2013/06/30]
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{scrbook}}
\ProcessOptions\relax
\LoadClass[paper=b4]{scrbook}

or alternative:

\ProvidesClass{wikibook}[2013/06/30]
\PassOptionsToPackage{b4paper}{typearea}
\LoadClass{scrbook}

test.tex:

\documentclass[12pt]{wikibook}   
\usepackage{bookman} 
\usepackage{lipsum}    
\begin{document}    
   \chapter{First example} 
     \section{Section one}    
       \lipsum[2-8]   
   \chapter{Second example} 
     \section{Section two} 
\end{document}

Generated pdf size is persistently a4.

You can define your own option paper and pass the value to typearea. — Marco Daniel, Jun 30 '13 at 09:38
Or, even better, \PassOptionsToPackage{paper=b4}{typearea} \LoadClass{scrbook} — karlkoeller, Jun 30 '13 at 09:41
I try karlkoeller recomendations, but without any effects. Generated pdf size is persistently a4. :-( — JardaFait, Jun 30 '13 at 10:16
Override typeare with \RequirePackage[b4paper]{geometry} after \LoadClass{scrartcls} and set the page parameters using \geometry. — egreg, Jun 30 '13 at 10:36

Package typearea does support ISO paper sizes including the B series. But the package does not automatically tell the paper size to the output driver. Then the layout is calculated for the specified paper size, but the media size of the PDF file gets the default size of the output driver. Package typearea provides option pagesize for telling the paper size to the output driver, see "Table 2.6.: Output driver for option pagesize=output driver" of KOMA-Script's documentation.

Example for the class file:

\ProvidesClass{wikibook}[2013/06/30]
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{scrbook}}
\ProcessOptions\relax
\PassOptionsToPackage{paper=b5,pagesize=auto}{typearea}
\LoadClass{scrbook}

jafan wanted to use b4 paper. Using such a format you get a warning from typearea package. Do you know why? – karlkoeller Jun 30 '13 at 14:36
@karlkoeller: Which warning? – Heiko Oberdiek Jun 30 '13 at 14:44
Package typearea Warning: Bad type area settings! – karlkoeller Jun 30 '13 at 14:45
@karlkoeller: I cannot reproduce it, because I do not get any warning (except for Overfull \hbox messages). – Heiko Oberdiek Jun 30 '13 at 15:30
Is it somehow possible to take an option such as paper=a5 given to my own class, pass this option to typearea and all other options to the koma script class? – Dan Sep 18 '13 at 21:36
@Dan: \DeclareOption{paper=a5}{\PassOptionsToPackage{\CurrentOption}{typearea}}. Supporting any paper sizes is more difficult. Then a key value option parser would be needed, see package kvoptions. – Heiko Oberdiek Sep 18 '13 at 21:41
