jigsaw - permute an image like a jigsaw puzzle


jigsaw [-display host:display.screen] [-delay usecs] [-speed ratio] [-complexity ratio] [-resolution int] [-thickness float] [-no-wobble] [-fps]


The jigsaw program loads an image, carves it up into a jigsaw puzzle, shuffles it, and then solves it.

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.


jigsaw accepts the following options:
-delay microseconds
 How long to wait between animation frames; default 20000.
-speed ratio
 Less than 1 for slower, greater than 1 for faster. Default 1.
-complexity ratio
 Less than 1 for simpler puzzles (fewer pieces), greater than 1 for more complex puzzles (more pieces). Default 1.
-resolution ratio
 Smoothness of the edges of the pieces. Less than 1 for rougher pieces (fewer polygons), greater than 1 for more smoother pieces (more polygons). Default 1.
-thickness float
 Thickness of the puzzle pieces (relative to their width). Default 0.06.
-no-wobble Keep the display stationary instead of very slowly wobbling back and forth.
-fps Display the current frame rate, polygon count, and CPU load.
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-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.


DISPLAY 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.
