+.SH DESCRIPTION
+.B blind-spiral-gradient
+prints a video with a spiral gradient to stdout,
+parameters for each from is read from each frame
+in stdin. The gradient is stored in all channels
+of the video.
+.P
+The video in stdin must contain 2 to 5 pixels per
+frame (inclusively). The first pixel shall point
+to the beginning of the gradient (where the value
+is 0) and the second pixel shall point to the end
+of the gradient (where the value is 1). In these
+pixels, the value of the first channel specifies
+the X-position and the value of the second
+channel specifies Y-position, the other channels
+are ignored. The angle of the vector between these
+two pixels determine the angle of the spiral.
+.P
+If there are four or five pixel in each frame in
+stdin, the third and fourth pixels are used to
+modify the shape of the spiral so that it is
+based on a superellipse instead of a circle.
+The first and second channel of third pixel creates
+a vector that is normalised. This vector and its
+normal creates the basis an imaginary coordinate
+system with its origo at the beginning of the spiral.
+The superellipse defined by the equation
+.RI | x |^ a +| y / m |^ b =1,
+where
+.I x
+is the distance from origo along the vector,
+.I y
+is the distance from origo along the vector's normal,
+.IR a ,
+.IR b ,
+and
+.I m
+are the values of the first, second, and third
+channels, respectively, in the fourth pixel. and has
+the distance 1 from origo at all points on it. If
+.IR a ,
+.IR b ,
+and
+.I m
+have the values 2, 2, and 1, respectively, these
+pixels have no effect on the spiral's shape.
+The third and fourth channels in the third pixel
+and the fourth channel in the fourth pixel are
+ignored.
+.P
+If there are three or five pixels, the channels,
+in order, in the last pixel, specifies the value
+.IR a ,
+.IR e ,
+.IR p ,
+and
+.IR k ,
+whose default values are 0, 1, 1, and 1, respectively.
+.I k
+is ignored unless
+.B -l
+is used. If
+.B -l
+is not used, the spiral is defined by the equation
+.IR r = a +( b /( 2\fBpi\fP )^ e ) v ^( ep ).
+If
+.B -l
+is used, the spiral is defined by the equation
+.RI log( r / k )= a +(log( b )/( 2\fBpi\fP )^ e ) v ^( ep ).
+.I r
+is defined as the distance from the center of the
+spiral,
+.I b
+is defined as the distance between the points

+.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.
