NAME
magnifier – GNOME Magnifier (gnome-mag)
SYNOPSIS
magnifier [-vhmif?] [-t|–target-display STRING] [-s|–source-display STRING] [–cursor-set=STRING] [–cursor-size=INT] [–cursor-scale-factor=FLOAT] [–cursor-color=LONG] [-v|–vertical] [-h|–horizontal] [-m|–mouse-follow] [-r|–refresh-time INT] [–mouse-latency=INT] [-z|–zoom-factor FLOAT] [-i|–invert-image] [–no-initial-region] [–timing-iterations=INT] [–timing-output] [–timing-pan-rate=INT] [–timing-delta-x=INT] [–timing-delta-y=INT] [–smoothing-type=STRING] [-f|–fullscreen] [–smooth-scrolling] [-b|–border-size INT] [-c|–border-color LONG] [–use-test-pattern] [–override-redirect] [–ignore-damage] [-?|–help] [–usage]
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.
