            3 blind-matrix-reflect - Create an affine 2D-transformation matrix for reflection about a line
            4 .SH SYNOPSIS
            5 .B blind-matrix-reflect
            6 [-c]
            7 .SH DESCRIPTION
            8 .B blind-matrix-reflect
            9 creates an affine 2D-transformation matrix for
           10 reflection about a line. The parameters for the
           11 matrix is read in stdin in format of a blind video,
           12 one matrix per frame in stdin created and printed
           13 to stdout in format of a blind video.
           14 .P
           15 Each frame in stdin shall contain exactly 2 pixels,
           16 the first pixel holds the x-value of the line going
           17 out from origo the image is reflected around, the
           18 second pixel holds the y-value of this line.
           19 .P
           20 The luma (encoding in the Y-channel, the second
           21 channel) multiplied by the alpha (the fourth channel)
           22 of the input pixels are used as the values. Each
           23 values in the resulting matrices are stored
           24 in all channels.
           25 .SH OPTIONS
           26 .TP
           27 .B -c
           28 Create different matrices for each channel. Use
           29 values from each channel in stdin to create
           30 matrices whose values are stored in the same
           31 channels in stdout.
