       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.


       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.


       -t, --target-display=STRING
              specify display on which to show magnified view

       -s, --source-display=STRING
              specify display to magnify

              cursor set to use in target display

              cursor size to use (overrides cursor-scale-factor)

              cursor scale factor

              cursor color (applied to 'black' pixels

       -v, -vertical
              split screen vertically (if target display = source display)

       -h, --horizontal
              split screen horizontally (if target display = source display)

       -m, --mouse-follow
              track mouse movements

       -r, --refresh-time=INT
              minimum refresh time for idle, in ms

              maximum mouse latency time, in ms

       -z, --zoom-factor=FLOAT
              zoom (scale) factor used to magnify source display

       -i, --invert-image
              invert the image colormap

              don't create an initial zoom region

              iterations to run timing benchmark test (0=continuous)

              display performance ouput

              timing pan rate in lines per frame

              pixels to pan in x-dimension each frame in timing update test

              pixels to pan in y-dimension each frame in timing update test

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

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

              use smooth scrolling

       -b, --border-size=INT
              width of border

       -c, --border-color=LONG
              border color specified as (A)RGB 23-bit value, Alpha-MSB

              use test pattern as source

              make the magnifier window totally unmanaged by the window manager

              ignore the X server DAMAGE extension, if present

       -?, --help
              command line help
