NAME
zoom - wander around magnified 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 takes an image, magnifies it, and scrolls around it,
fatbits-style.
The image that it manipulates will be grabbed from the portion of the
screen underlying the window, or from the system's video input, or from
a random file on disk, as indicated by the grabDesktopImages, grabVide-
oFrames, and chooseRandomImages options in the ~/.xscreensaver file;
see xscreensaver-demo(1) for more details.
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 consecutive copied regions
(only effective when -lenses used).
-lensoffsety pixels
Distance in Y direction between consecutive 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.

On most web browsers you can double click any word on this page to see what definitions I have for that word.
This dictionary server is not an authoratative source of information for anything. Like almost everything at sorabji.com, I set this up for my own purposes. In this case the purpose is to
browse words and ideas at random. An automatically generated page that produces 1000 Random Words
is my gateway to this resource. I also attempt a word of the day project,
in which I attempt to write something about myself starting with interesting words that I find through the Wordswarm Random Words Pages. I have made
available the complete 1828 Webster's Dictionary, which many feel is the greatest English dictionary ever published.
Other random links of mine include the Sorabji.com Random Link, which sends you to one of
over 7,000 pages on my web sites; the Face Server produces random images of
human faces; clicking the Random WAYD link shows you a random posting to my "What Are You Doing?" board; the Random USPS
Mailbox link sends you to a page with information about a random mailbox; and the random pictures page page of sorabji.com shows one of over 11,000 random images any time you load the page. On an unrelated note, I have begun making several thousand pages of legal documents searchable.
