|pixdsplit [options] [infile]|
Pixdsplit separates out interwoven characters and doubles from a single input stream. It treats the stream as consisting of successive "pixels", each of which is made up of n unsigned chars followed by m 64-bit doubles, and writes the chars to one output stream and the doubles to another. The pixels are read from infile if it is specified; otherwise, pixdsplit reads from the standard input.
The command-line options and their meanings are:
-c charfileCauses pixdsplit to write the chars to the specified file. If charfile is the empty string, then pixdsplit does not write out the chars. Default is "-", so the chars are written to the standard output.
-d doublefileCauses pixdsplit to write the doubles to the specified file. If doublefile is the empty string, then pixdsplit does not write out the doubles. Default is , so the doubles are not output.
-# n.mDefines a pixel to be made up of n unsigned chars and m 64-bit doubles, where n and m are positive integers. Either of n and m (but not both) may be omitted and if m is omitted, then the separating period, too, may be omitted. The variable for which a value was omitted retains its previous value. By default, n = 3 and m = 1, so the input stream is assumed to be in pixd(5) format as produced by the -d option of rt(1).
pixdsplit file.pixd | pix-fb
extracts the pix(5) data from file.pixd, sending it for display to pix-fb(1), while
pixdsplit -# 3.2 -c -d coords datafile
ignores the RGB information in datafile but writes its pairs of doubles to coords.
