    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 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, grabVideoFrames, 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 similarly 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.
