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.Options
