1 .TH BLIND-MATRIX-TRANSLATE 1 blind 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. 36 .SH SEE ALSO 37 .BR blind (7), 38 .BR blind-from-text (1), 39 .BR blind-matrix-orthoproject (1), 40 .BR blind-matrix-reflect (1), 41 .BR blind-matrix-rotate (1), 42 .BR blind-matrix-scale (1), 43 .BR blind-matrix-shear (1), 44 .BR blind-matrix-transpose (1), 45 .BR blind-multiply-matrices (1) 46 .SH AUTHORS 47 Mattias Andrée 48 .RI < maandree@kth.se >
