       fbanim -	animate	small images on	framebuffer using hardware pan and

       fbanim [-irv] [-S screen	squaresize] [-W	screen width]
	      [-N screen height] [-s file squaresize] [-w file width]
	      [-n file height] [-p npasses] width nframes [fps]

       Fbanim assumes that the current framebuffer (determined by environment
       variable	FB_FILE) contains a collection of small	square images
       AcAAtiledAcAA together by pixtile(1). This permits a limited sequence
       of low resolution images	to be viewed at	various	speeds,	to create the
       sensation of motion, or to highlight the	differences between the
       frames. The typical use of this program is to animate sequences of
       64x64 or	128x128	tiles generated	by animation studies. It can also be
       used to create AcAAblink	comparisonsAcAA	between	a small	number of
       large images.

       The width of each tile is specified by the width	argument, and the
       number of tiles is specified by the nframes argument. The optional
       argument	fps specifies the number of frames (tiles) per second to be
       displayed. 24 fps is the	standard movie rate, 30	the standard video
       rate. Slower rates may also be used. The	default	is 8 frames/second.

       By default, the framebuffer is assumed to be loaded with	a 512x512
       pixel image. Alternatively, the -SWN flags can be used in the normal
       way to specify the size of the screen (see brlcad(1)).

       By default, the sequence	of tiles is considered to be a circular
       (repeating) sequence, i.e., the first tile immediately follows the last
       one. If this is not the case, the -r flag will cause the	sequence to
       AcAArockAcAA from beginning to end to beginning,	which is sometimes
       more pleasing.

       The -v flag will	cause the frame	number and center coordinates of each
       frame to	be printed as they are passed to fb_window(), for debugging

       By default, the fbanim program repeats for 100 passes. When creating
       demonstration scripts, it may be	desirable to specify the number	of
       passes through the animation. The -p~A npasses option is used to
       indicate	this.

       For compatibility with old animation images which were generated	by
       fourth-quadrant programs, where the first image starts in the upper
       left corner of the screen rather	than the lower left corner, the	-i
       flag is used to indicate	this inverse order.
