plsdidev
: Set parameters that define current
device-space window
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,
jx, and
jy
are all 0. aspect
is set to a device-specific value.
