CHAPTER 4. SPECIAL DOCUMENT CLASSES
4.8.1
Overview
The LYX document classes article (koma-script), report (koma-script), book
(koma-script), and letter (koma-script) correspond to the LATEX document classes
scrartcl.cls, scrreprt.cls, scrbook.cls, and scrlettr.cls, resp. of the
Koma-Script family. They are replacements for the standard document classes
article.cls, report.cls, book.cls and letter.cls, resp., and fit better to
European typography conventions in a number of points.
• Standard character size is 11pt in article (koma-script), report (komascript), and book (koma-script), and 12pt in letter (koma-script).
• Headings, labels of the description environment, and a number of elements
of the letter (koma-script) document class are set in a bold sans serif
font.2 The numbering of chapter headings is made in the same way as the
numbering of section headings, that is without the extra line “Chapter. . . ”.
In addition, the appearance of the headings can be modified by using a
number of options (in LYX to be entered in the field Extra Options of the
dialog Layout ! Document). A detailed German description of these options
can be found in the Koma-Script documentation scrguide.
• The main means in the Koma-Script document classes to design the type
area are the options BCOR and DIV (in LYX to be entered in the extra class options field in the dialog Document ! Settings). They make a
clearer modification of page margins possible as do the options of the
dialog Document ! Settings. A detailed German description of these and
other type area options can be found in the Koma-Script documentation
scrguide.
• The LATEX document classes of the Koma-Script family define a number
of additional commands. Those part of it which makes sense in LYX is
implemented in corresponding paragraph types.
A detailed German description of the LATEX document classes of the KomaScript family can be found in the Koma-Script documentation scrguide.3 The
following sections describe only those aspects, which are relevant in LYX.
4.8.2
article (koma-script), report (koma-script), and book
(koma-script)
The document classes article (koma-script), report (koma-script), and book (komascript) are implemented in the layout files scrartcl.layout, scrreprt.layout,
2 There is a big difference between the bold sans serif old cm fonts and new ec fonts,
especially in the appearance of headings. In comparison, the ec bold sans serif fonts look a bit
thin. Here the LATEX package cmsd.sty by Walter Schmidt helps to produce the “usual”
appearance when using the ec fonts.
3 There is an English translation screnggu, but it is not a complete one.
