The parameters for the +matrix is read in stdin in format of a blind video, +one matrix per frame in stdin created and printed +to stdout in format of a blind video. +.P +Each frame in stdin shall contain exactly 2 pixels, +the first pixel holds the x-value of the vector the +image is projected along, the second pixel holds the +y-value of this vector. +.P +The luma (encoding in the Y-channel, the second +channel) multiplied by the alpha (the fourth channel) +of the input pixels are used as the values. Each +values in the resulting matrices are stored +in all channels. +.SH OPTIONS +.TP +.B -c +Create different matrices for each channel. Use +values from each channel in stdin to create +matrices whose values are stored in the same +channels in stdout. +.SH SEE ALSO +.BR blind (7), +.BR blind-from-text (1), +.BR blind-matrix-reflect (1), +.BR blind-matrix-rotate (1), +.BR blind-matrix-scale (1), +.BR blind-matrix-shear (1), +.BR blind-matrix-translate (1), +.BR blind-matrix-transpose (1) +.SH AUTHORS +Mattias Andrée +.RI < maandree@kth.se > |
