                      2: .CT 1 graphics
                      3: .SH NAME
                      4: view2d \- movie of a function f(x, y, t)
                      5: .SH DESCRIPTION
                      6: Files of this format are produced by functions in
                      7: .IR view2d (3),
                      8: and displayed by commands in
                      9: .IR view2d (1).
                     10: A movie file consists of one or more frames,
                     11: each consisting of a header and a sequence
                     12: of 16-bit signed integer values for each
                     13: pixel, scanned left to right and bottom to top.
                     14: (Left-to-right is the inner loop.)
                     15: .PP
                     16: The header consists of the 32-bit magic number 0135246,
                     17: then eight 16-bit integers:
                     18: .TP
                     19: .I VER
                     20: The version number.
                     21: .TP
                     22: .I NX, NY
                     23: The number of pixels in the frame.
                     24: These may not vary from frame to frame.
                     25: .TP
                     26: .I u, v
                     27: relate pixel values
                     28: .I p
                     29: in the file to user function values
                     30: .I f
                     31: by
                     32: .IP

                     34: =
                     35: .I u
                     36: \+
                     37: .if t .I f\^\(mu2\u\-v\d.
                     38: .if n .IR f/ 2 **v.
                     39: .TP
                     40: .I FIXUV
                     41: normally 0;  1 if
                     42: .I u, v, PMIN, PMAX
                     43: of first frame
                     44: give a bound on the data in the entire file.
                     45: .TP
                     46: .I PMIN, PMAX
                     47: limits of the data; only used when
                     48: .IR FIXUV =1.
                     49: .LP
                     50: and finally a 16-byte
                     51: .SM ASCII
                     52: representation of a floating point value:
                     53: .TP
                     54: .I TIME
                     55: is a frame index, typically set to simulated time or
                     56: to an iteration counter.
                     57: This need not be uniformly spaced from frame to frame,
                     58: but should be nondecreasing.
                     59: .PP
                     60: The range of displayable pixel values is [\-32765,32765].
                     61: Values below this range are deemed out of bounds
                     62: and not plotted; values above are reserved.
                     63: .SH "SEE ALSO"
