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. 32 .SH SEE ALSO 33 .BR blind (7), 34 .BR blind-from-text (1), 35 .BR blind-matrix-orthoproject (1), 36 .BR blind-matrix-reflect (1), 37 .BR blind-matrix-rotate (1), 38 .BR blind-matrix-scale (1), 39 .BR blind-matrix-shear (1), 40 .BR blind-matrix-translate (1), 41 .BR blind-multiply-matrices (1) 42 .SH AUTHORS 43 Mattias Andrée 44 .RI < maandree@kth.se >
