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.
