#X text 695 208 For an image sequence it is useful to have sequential
numbering \, but in other instances it is more useful to name with
a time stamp (for example \, if the patch crashes and you need to restart
without overwriting previous images...).;

#X text 23 328 For writing to a named pipe created with mkfifo (say
it is called "fifo.ppm") \, you would "open ppm file fifo.ppm" once
\, then send multiple image grids (of the same size) to #out \, and
only "close" after the last image has been sent.;
#X text 580 325 Note: when saving to a named pipe \, gridflow (and
Pd) will appear to hang until the data is read from the other end of
the fifo. When experimenting try "cat fifo.ppm >/dev/null" to magically
bring Pd back to life.;
