1 .TH BLIND-MATRIX-ORTHOPROJECT 1 blind 2 .SH NAME 3 blind-matrix-orthoproject - Create an affine 2D-transformation matrix for othogonal projection 4 .SH SYNOPSIS 5 .B blind-matrix-orthoproject 6 [-c] 7 .SH DESCRIPTION 8 .B blind-matrix-orthoproject 9 creates an affine 2D-transformation matrix for 10 othogonal projection. 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 vector the 17 image is projected along, the second pixel holds the 18 y-value of this vector. 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. 32 .SH SEE ALSO 33 .BR blind (7), 34 .BR blind-from-text (1), 35 .BR blind-matrix-reflect (1), 36 .BR blind-matrix-rotate (1), 37 .BR blind-matrix-scale (1), 38 .BR blind-matrix-shear (1), 39 .BR blind-matrix-translate (1), 40 .BR blind-matrix-transpose (1), 41 .BR blind-multiply-matrices (1) 42 .SH AUTHORS 43 Mattias Andrée 44 .RI < maandree@kth.se >
