pub fn PEC(s: Option<PresentationExpandContract>) -> ControlFunction<'static>
Expand description
Presentation Expand or Contract.
PEC
is used to establish the spacing and the extent of the graphic characters for subsequent text. The spacing is
specified in the line as multiples of the spacing established by the most recent occurrence of SET CHARACTER SPACING
(SCS
) or of SELECT CHARACTER SPACING (SHS
) or of SPACING INCREMENT (SPI
) in the data stream. The extent
of the characters is implicitly established by these control functions. The established spacing and the extent
remain in effect until the next occurrence of PEC
, of SCS
, of SHS
or of SPI
in the data stream.
The default value for s
is PresentationExpandContract::Normal
.
