.TH BLIND-TRIANGULAR-WAVE 1 blind
.SH NAME
blind-triangular-wave - Apply triangular-wave repetition to gradient
.SH SYNOPSIS
.B blind-triangular-wave
[-es]
.SH DESCRIPTION
.B blind-triangular-wave
reads a video from stdin, applies a filter to
each channel to it, and prints the result to
stdout. The filter is designed for applying
repetition to a gradient, and thus assumes the
range of visible values is [0, 1]. The applied
filter creates a triangular wave.
.SH OPTIONS
.TP
.B -e
Apply optimisation that assumes all channels
are identical.
.TP
.B -s
Apply a variation of the filter that is
more appropriate for spiral gradient.
