Userparams and
systemparams
The following keys have been added to the userparams and
systemparams dictionaries to let the user modify the Image Menu
options from a PostScript job. The new keys, their possible values,
and the corresponding Image Menu values are shown below.

ImageInvert
ImageScaling
ImageOrientation
The Values in the table are integers.
When set using the setsystemparams operator, the values persist
from job to job, like when they are set using the Image Menu.
When set using the setuserparams operator, the values only persist
until reset or the end of the job. Changes to userparams are subject
to Save and Restore. The default userparams at the beginning of a
job are equal to the current systemparams values.
