      1 .TH BLIND-MATRIX-TRANSPOSE 1 blind
      2 .SH NAME
      3 blind-matrix-transpose - Create an affine 2D-transformation matrix for transposition
      4 .SH SYNOPSIS
      5 .B blind-matrix-transpose
      6 [-c]
      7 .SH DESCRIPTION
      8 .B blind-matrix-transpose
      9 creates an affine 2D-transformation matrix for
     10 transposition. The parameters for the matrix is read
     11 in stdin in format of a blind video, one matrix
     12 per frame in stdin created and printed to stdout
     13 in format of a blind video.
     14 .P
     15 Each frame in stdin shall contain exactly 1 pixel,
     16 this pixel holds degree of the transposition, 0
     17 meaning no transposition at all, 1 meaning full
     18 transposition.
     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.
