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. | |
