NAME
zoom - wander around magified desktop
SYNOPSIS
zoom [-display host:display.screen] [-foreground color] [-background
color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay
usecs] [-lenses] [-pixwidth pixels] [-pixheight pixels] [-pixspacex
pixels] [-pixspacey pixels] [-lensoffsetx pixels] [-lensoffsety pixels]
DESCRIPTION
The zoom program magnifies a portion of the desktop and moves around.
OPTIONS
zoom accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a monochrome display.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
visual.
-delay microseconds
Slow it down.
-lenses Instead of doing magnification we just copy an offset region
from the original image. If lensoffsetx < pixwidth (and simi‐
larly for Y) then consecutive regions will overlap, giving the
effect of looking through an array of lenses.
-pixwidth pixels
Width of the magnified pixels.
-pixheight pixels
Height of the magnified pixels.
-pixspacex pixels
Amount of black space between magnified pixels (X direction).
-pixspacey pixels
Amount of black space between magnified pixels (Y direction).
-lensoffsetx pixels
Distance in X direction between consective copied regions (only
effective when -lenses used).
-lensoffsety pixels
Distance in Y direction between consective copied regions (only
effective when -lenses used).
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
