21 The GNOME magnifier (gnome-mag) provides a command-line interface for
22 standalone use, although its primary goal is to provide a set of magni‐
23 fication services for use by other client applications and assistive
24 technologies, like Gnopernicus, Orca or LSR.
25 This magnifier is compatible with operating systems using X Window Sys‐
27 tem, although the magnifier will have a better performance and func‐
28 tionality when the Damage and Fixes extensions are present.
29
31 A desktop screen magnifier. If present, the Region Of Interest (ROI)
32 for the magnifier can be driven by a screen reader via the Assistive
33 Technology Service Provider Interface (ATSPI); otherwise, the magnifier
34 will be centered to the pointer position.
