Usage

Here’s an example how to convert a stream of PNGs to an animated GIF. This example uses:

• seq to create a sequence of numbers (stream: many lines with a number each line), uses

• xargs to call a fictitious program ./tool that produces a PNG for each call (stream: sequence of PNGs)

• eachpng calling ImageMagick convert for each PNG to convert it to GIF (stream: sequence if GIFs)

• gifsicle operating taking the sequence of GIFs to produce an animated GIF

$ seq 0 33 12000 | \
  xargs -L 1 -I TC ./tool -t TC -o - | \
  eachpng convert - GIF:- | \
  gifsicle --multifile --delay 3 -O3 >out.gif
