      2 .SH NAME
      3 blind-translate - Perform framewise translation of a video
      4 .SH SYNOPSIS
      5 .B blind-translate
      6 [-pw]
      7 .I translation-stream
      8 .SH DESCRIPTION
      9 .B blind-translate
     10 reads a video from stdin and translation operands from
     11 .IR translation-stream ,
     12 and perform framewise translation of the video and
     13 prints the resulting video to stdout.
     14 .P
     15 .I translation-stream
     16 is a video that is 1 pixel wide and 1 pixel high.
     17 The first pixel value in a frame is used as the
     18 translation value for the X-axis in the same frame
     19 in the video, and the second pixel value is used
     20 as the translation value for the Y-axis. The
     21 remaining two pixel values are ignored.
     22 .P
     23 If stdin is longer than
     24 .IR translation-stream ,
     25 the remainder of stdin is printed with the last translation
     26 or no translation if
     27 .I translation-stream
     28 does not contain any translations. If stdin is shorter than
     29 .IR translation-stream ,
     30 the remainder of
     31 .I translation-stream
     32 is ignored but may be partially read.
     33 .SH OPTIONS
     34 .TP
     35 .B -w
     36 Wrap video around the edges.
     37 .TP
     38 .B -p
     39 The values in
     40 .I translation-stream
     41 is to be treat as the position, measured form the
     42 top-left corner, in the input video that shall be
     43 used at the top-left corner of the output video.
     44 .SH REQUIREMENTS
     45 .B blind-translate
     46 requires enough free memory to load a full frames into
     47 memory if
     48 .B -w
     49 is used or a frame row otherwise. A frame or frame row
     50 requires 32 bytes per pixel it contains.
