NAMEzoom - wander around magnified desktop
SYNOPSISzoom [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-duration secs] [-lenses] [-pixwidth pixels] [-pixheight pixels] [-pixspacex pixels] [-pixspacey pixels] [-lensoffsetx pixels] [-lensoffsety pixels] [-fps]
DESCRIPTIONThe 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.
OPTIONSzoom accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- If on a color display, pretend we're on a monochrome display.
- 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.
- -duration seconds
- How long to run before loading a new image. Default 120 seconds.
- 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 consecutive copied regions (only effective when -lenses used).
- -lensoffsety pixels
- Distance in Y direction between consecutive copied regions (only effective when -lenses used).
- to get the default host and display number.
- to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
