    NAME

    vidwhacker - grab images and apply random filters to them
     
    

    SYNOPSIS

    vidwhacker [-display host:display.screen] [-root] [-verbose] [-stdin] [-stdout] [-delay seconds] [-directory directory]  

    DESCRIPTION

    The vidwhacker program grabs an image from disk, or from the system's video input, then applies random image filters to it, and displays the result. The vidwhacker program does not terminate until killed.

    It depends heavily on the various PBM tools (e.g., ppmrelief(1).)

    Selection of random image files is done by running the xscreensaver-getimage-file(1) program. Capture of video frames (if requested) is done by running the xscreensaver-getimage-video(1) program. The options of whether to do video, and which directory to search for images, are specified in the ~/.xscreensaver file.  

    OPTIONS

    vidwhacker accepts the following options:
    -root
    Draw on the root window. This is the default.
    -verbose
    Print diagnostics.
    -stdin
    Instead of grabbing an image from disk or video, read an image to maniupulate from stdin. This image must be in ppm(5) format. The program will still perform repeated random image transformations, but it will always use this one image as its starting point.
    -delay seconds
    How long to sleep between images. Default 5 seconds (the actual elapsed time is significantly longer, due to processing time.)
    -stdout
    Instead of displaying the image on a window or on the root, write the new image on stdout, and exit.
    -directory directory
    Use this directory instead of the imageDirectory specified in the ~/.xscreensaver file.
     

    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.
     

    BUGS

    It's slow.  

    TO DO

    It might be interesting to rewrite this to use gimp(1) plugins instead of the pbm tools. It probably wouldn't be any faster, but there would be a wider variety of effects available.
