AVAILABILITY

       The GNOME magnifier (gnome-mag) provides a  command-line  interface  for  standalone  use,
       although  its  primary goal is to provide a set of magnification services for use by other
       client applications and assistive technologies, like Gnopernicus, Orca or LSR.

       This magnifier is compatible with operating systems using X Window  System,  although  the
       magnifier  will  have  a  better  performance  and functionality when the Damage and Fixes
       extensions are present.

DESCRIPTION

       A desktop screen magnifier.  If present, the Region Of Interest (ROI)  for  the  magnifier
       can  be  driven by a screen reader via the Assistive Technology Service Provider Interface
       (ATSPI); otherwise, the magnifier will be centered to the pointer position.

       --smoothing-type=STRING
              image smoothing algorithm to apply (bilinear-interpolation | none)

       -f, --fullscreen
              fullscreen magnification, covers entire target display  [REQUIRES  --source-display
              and --target-display]

       --smooth-scrolling
