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 cardinal sine-wave. +.P +If +.I theta0-stream +is specified, it must be a video with only +one pixel per frame. When applying the sine +function, it is applied to the sum of the +pixel it is applied to and the pixel in +the same frame in +.IR theta0-stream . +.SH NOTES +.BR blind-arithm (1) +with the +.B mul +and +.B div +operators can be used to stretch the wave. +.SH OPTIONS +.TP +.B -e +Apply optimisation that assumes all channels +are identical. If +.I theta0-stream +is specified, the values from its second channel +(the Y channel) are used for all channels. +.SH SEE ALSO +.BR blind (7), +.BR blind-arithm (1), +.BR blind-double-sine-wave (1), +.BR blind-round-wave (1), +.BR blind-sawtooth-wave (1), +.BR blind-sine-wave (1), +.BR blind-triangular-wave (1), +.BR blind-cone-gradient (1), +.BR blind-linear-gradient (1), +.BR blind-radial-gradient (1), +.BR blind-spiral-gradient (1), +.BR blind-square-gradient (1) +.SH AUTHORS +Mattias Andrée +.RI < maandree@kth.se > -- cgit v1.2.3-70-g09d2
