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.
