plsdidev
( | mar, |
aspect, | |
jx, | |
jy) ; |
Set relative margin width, aspect ratio, and relative
justification that define current device-space window. If you want to just use the previous value for any of
these, just pass in the magic value PL_NOTSET. It is unlikely that one
should ever need to change the aspect ratio but it's in there for
completeness.
If plsdidev
is not called the default values
of
,
mar
, and
jx
are all 0. jy
is set to a device-specific value.
