	4 .SH SYNOPSIS
	5 .B blind-matrix-scale
	6 [-c]
	7 .SH DESCRIPTION
	8 .B blind-matrix-scale
	9 creates an affine 2D-transformation matrix for
	10 scaling. 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 scale factor for the
	17 width and the second pixel holds the scale factor
	18 for the height.
	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.
