@Begin
@PP
scale. @Index { @@Scale symbol }
This symbol geometrically scales its right parameter by the scale factor
given in its left parameter:
@ID @Code "1.0 @Scale Hello 2.0 @Scale Hello 0.5 @Scale Hello"
has result
@ID { 1.0 @Scale Hello 2.0 @Scale Hello 0.5 @Scale Hello }
The left parameter can be two scale factors, in which case the first
applies horizontally, and the second vertically:
@ID @Code "{0.5 2.0} @Scale Hello"
has result
@ID { {0.5 2.0} @Scale Hello }
The left parameter may be empty, in which case Lout will scale the
object by a common factor horizontally and vertically so as to occupy
all available horizontal space:
@ID @Code "{} @Scale { Hello world }"
has result
@LD {} @Scale { Hello world }
The right parameter may be any object. @@Scale has both a @@OneCol and
a @@OneRow effect, and the marks of the result coincide with the principal
marks of the right parameter.
