@Section
@Title { Page size and page orientation }
@Tag { pagesize }
@Begin
@PP
This section explains how to use the setup file options that determine
page size and page orientation. Here they are with their default values:
page.type @Index @Code "@PageType"
@ID @OneRow @Code @Verbatim {
@PageType { A4 }
@PageWidth {}
@PageHeight {}
@PageOrientation { Portrait }
}
The default value at your site may be different, since installers of
Lout are recommended to set it to the usual size of a piece of paper
at their location. The easy way to change the page size is to set
the @Code "@PageType" option to the name of the paper you use:
@ID @Tab
vmargin { 0.5vx }
@Fmtb { @Col ! @Col ! @Col @I @RR B ! @Col @I @RR C }
@Fmta { @Col @Code { "@PageType {" A "}" } ! @Col ! @Col @Code @CC B !
@Col @Code @CC C }
{
@Rowb B { width in points } C { height in points }
@Rowa A { Letter } B { 612p } C { 792p }
@Rowa A { Tabloid } B { 792p } C { 1224p }
@Rowa A { Ledger } B { 1224p } C { 792p }
@Rowa A { Legal } B { 612p } C { 1008p }
@Rowa A { Statement } B { 396p } C { 612p }
@Rowa A { Executive } B { 540p } C { 720p }
@Rowa A { A0 } B { 2380p } C { 3368p }
@Rowa A { A1 } B { 1684p } C { 2380p }
@Rowa A { A2 } B { 1190p } C { 1684p }
@Rowa A { A3 } B { 842p } C { 1190p }
@Rowa A { A4 } B { 595p } C { 842p }
@Rowa A { A5 } B { 420p } C { 595p }
@Rowa A { B4 } B { 729p } C { 1032p }
@Rowa A { B5 } B { 516p } C { 729p }
@Rowa A { Folio } B { 612p } C { 936p }
@Rowa A { Quarto } B { 610p } C { 780p }
@Rowa A { 10x14 } B { 720p } C { 1008p }
}
This will automatically assign the widths and heights shown above to
the @Code "@PageWidth" and @Code "@PageHeight" options, so you don't
have to worry about those options. If your paper size is not on this
list, set @Code "@PageType" to @Code Other and supply your own width
and height:
page.width @Index @Code "@PageWidth"
page.height @Index @Code "@PageHeight"
@ID @Tab
vmargin { 0.5vx }
@Fmta { @Col @Code A }
{
@Rowa A { "@PageType { Other }" }
@Rowa A { "@PageWidth { 12.0c }" }
@Rowa A { "@PageHeight { 18.0c }" }
}
The width and height may each be any length (Section {@NumberOf objects}),
and do not have to be in points.
@PP
The basic page orientations are @I portrait and @I landscape:
page.orientation @Index @Code "@PageOrientation"
@ID @Tab
@Fmta { @Col 8c @Wide @Code A ! @Col B }
{
@Rowa
A { "@PageOrientation { Portrait }" }
B { @Box 1.0c @Wide 1.4c @High { Hello } }
@Rowa
@Rowa
A { "@PageOrientation { Landscape }" }
B { @Box 1.4c @Wide 1.0c @High { Hello } }
}
When changing to {@Code Landscape}, do not change the page type, page
width, or page height, and do not change the way you feed your paper
into the printer. Lout knows what to do.
@PP
Two other orientations are provided which are 180@Degree rotations of
the basic ones:
@ID @Tab
@Fmta { @Col 8c @Wide @Code A ! @Col B }
{
@Rowa
A { "@PageOrientation { ReversePortrait }" }
B { @Box 1.0c @Wide 1.4c @High { //1rt &1rt 180d @Rotate Hello } }
@Rowa
@Rowa
A { "@PageOrientation { ReverseLandscape }" }
B { @Box 1.4c @Wide 1.0c @High { //1rt &1rt 180d @Rotate Hello } }
}
@Code ReverseLandscape might be useful when post-processing the PostScript
output to print two landscape pages per sheet. The @Code "@PageOrientation"
symbol is available at the start of a document, as well as in the setup
file, like {@Code "@InitialFont"} and {@Code "@PageHeaders"}.
