            2 .SH NAME
            3 blind-matrix-translate - Create an affine 2D-transformation matrix for translation
            4 .SH SYNOPSIS
            5 .B blind-matrix-translate
            6 [-c]
            7 .SH DESCRIPTION
            8 .B blind-matrix-translate
            9 creates an affine 2D-transformation matrix for
           10 translation. 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 2 pixel,
           16 the first pixel holds the number of pixels the
           17 image shall be translated rightwards, and the
           18 second pixel holds the number of pixels the
           19 image shall be translated downwards.
           20 .P
           21 The luma (encoding in the Y-channel, the second
           22 channel) multiplied by the alpha (the fourth channel)
           23 of the input pixels are used as the values. Each
           24 values in the resulting matrices are stored
           25 in all channels.
           26 .SH OPTIONS
           27 .TP
           28 .B -c
           29 Create different matrices for each channel. Use
           30 values from each channel in stdin to create
           31 matrices whose values are stored in the same
           32 channels in stdout.
           33 .SH NOTES
           34 The image upwards rather than downwards if the
           35 Y-axis grows upwards rather than downwards.
