NAME
magnifier - standalone magnification service for GNOME
SYNOPSIS
magnifier --fullscreen | --horizontal | --vertical [--border-color=long] [--border-size=int] [--cursor-color=long] [--cursor-scale-fac- tor=float] [--cursor-set=string] [--cursor-size=int] [--help] [--invert-image] [--mouse-follow] [--mouse-latency=int] [--no-initial-region] [--override-redirect] [--refresh-time=int] [--smooth-scrolling] [--smoothing-type=string] [--source-display=string] [--target-dis- play=string] [--timing-delta-x=int] [--timing-delta-y=int] [--timing-iterations=int] [--timing-output] [--timing-pan-rate=int] [--usage] [--use-test-pattern] [--zoom-factor=float]
DESCRIPTION
magnifier provides a simple fullscreen or splitscreen magnifier for GNOME. magnifier also provides a magnification service API for use by assistive technologies such as orca, and is more commonly used in this ser- vice mode.
OPTIONS
The following options are supported: --border-color=long Specify the border color as (A)RGB 23-bit value, Alpha-MSB. You can also use -c to specify this option. --border-size=int Specify the width of the border. You can also use -b to specify this option. --cursor-color=long Specify the cursor color, applied to 'black'pixels. --cursor-scale-f=float Specify the cursor scale factor. --cursor-set=string Specify the cursor set touse in the target display. --cursor-size=int Specify the cursor size to use. This option overrides the --cursor-scale-factor option. --fullscreen Specify fullscreen magnification, which covers the entire target display. If you specify this option, you must also specify the --source-display and --target-display options. You can also use -f to specify this option. --help Display help message. You can also use -? to specify this option. --horizontal Split the screen horizontally, if the target display is the same as the source display. You can also use -h to specify this option. --invert-image Invert the image colormap. You can also use -i to specify this option. --mouse-follow Track mouse movements. You can also use -m to specify this option. --mouse-latency=int Specify the maximum mouse latency time, in ms. --no-initial-region Do not create an initial zoom region. --override-redirect Make the magnifier window completely unmanaged by the window manager. --refresh-time=int Specify the minimum refresh time for idle, in ms. You can also use -r to specify this option. --smooth-scrolling Use smooth scrolling. --smoothing-type=string Specify the image smoothing algorithm to apply: either bilinear-interpolation or none. --source-display=string Specify the display to magnify. You can also use -s to specify this option. --target-display=string Specify the display on which to show the magnifie view. You can also use -t to specify this option. --timing-delta-x=int Specify the number of pixels to pan in the x-dimension each frame in the timing update test. --timing-delta-y=int Specify the number of pixels to pan in the y-dimension each frame in the timing update test. --timing-iterations=int Specify the number of iterations to run the timing benchmark test (0=continuous) --timing-output Display performance output. --timing-pan-rate=int Specify the timing pan rate in lines per frame. --usage Display a brief usage message. --use-test-pattern Use the test pattern as the source. --vertical Split the screen vertically, if the target display is the same as the source display. You can also use -v to spec- ify this option. --zoom-factor=float Specify the zoom (scale) factor used to mag-nify the source display. You can also use -z to specify this option.
EXTENDED DESCRIPTION
magnifier provides a simple screen magnification utility for GNOME, offering splitscreen or fullscreen magnification. You should specify one of the following options: -v (vertical splitscreen magnification), -h (horizontal splitscreen mag-nification), or -f (fullscreen magni- fication). If fullscreen magnification is specified, the source and target displays must also be specified. Note that fullscreen magnification requires that two separate X server graphical screens are available. The source display can be virtual, that is, not connected to a physical graphics subsystem. The target display must be connected to a physical display device. Source and tar- get displays are of the following form: [hostname]:server_number.screen_number Most users of magnifier in standalone mode specify the -m option, which causes the magnified region to be continually recentered on the onscreen pointer position in the source display. magnifier capabilities include recoloring the mouse pointer, specifying the magnification factor for source to target conversion, separate magnification factors for the mouse pointer, and whether or not to apply smoothing or averaging to the resized image.
EXAMPLES
Example 1: Displaying a Fullscreen Magnified Image of Screen ":0.0" on Target Display ":0.1", at a Magnification Factor of 3.5, With Mouse Tracking: example% magnifier -f -m -s:0.0 -t:0.1 -z3.5 Example 2: Displaying a Vertical Splitscreen Magnified Image on the Default Display, With a Scale Factor of 4 and a Horizontal Scale Factor of 3, Using Bilinear Interpolation to Smooth Resulting Image example% magnifier -v -m -z 4 --cursor-scale-factor=3 --smoothing-type=bilinear-interpolation
ENVIRONMENT VARIABLES
magnifier uses $DISPLAY if the source or target displays are unspecified at startup.

NOTES
If you need fullscreen magnification due to visual difficulties, you might benefit from using a full-featured assistive technology such as orca instead. Written by Bill Haneman, Sun Microsystems Inc., 2004. SunOS 5.11 7 Aug 2008 magnifier(1)
