      1 .TH BLIND-TRIANGULAR-WAVE 1 blind
      2 .SH NAME
      3 blind-triangular-wave - Apply triangular-wave repetition to gradient
      4 .SH SYNOPSIS
      5 .B blind-triangular-wave
      6 [-es]
      7 .SH DESCRIPTION
      8 .B blind-triangular-wave
      9 reads a video from stdin, applies a filter to
     10 each channel to it, and prints the result to
     11 stdout. The filter is designed for applying
     12 repetition to a gradient, and thus assumes the
     13 range of visible values is [0, 1]. The applied
     14 filter creates a triangular wave.
     15 .SH OPTIONS
     16 .TP
     17 .B -e
     18 Apply optimisation that assumes all channels
     19 are identical.
     20 .TP
     21 .B -s
     22 Apply a variation of the filter that is
     23 more appropriate for spiral gradient.
