Example Usage of python animated_clients.py.txt
|
|
|
|
python animated_clients.py.txt --indir=./example_input/ --outdir=./example_output/ --header="Header string" --footer="Footer string"
|
|
|
|
This script is still somewhat fragile and does not yet do all the path
|
|
and file existance checking that it should. To use the example
|
|
invocation you will need to make sure that the indir and outdir
|
|
locations exists.
|
|
|
|
indir is used to hold file inputs that the script needs.
|
|
The example invocation requires that indir holds:
|
|
ips-with-epoch.txt : file with ip clients and epoch timestamp
|
|
glds05ag30.asc : population density data
|
|
regions.txt : region definitions
|
|
|
|
indir defaults to ./
|
|
|
|
if the file saved_data.pickle exists in outdir, this file will be loaded
|
|
in an attempt to create image frames based on previous timestamp
|
|
imformatin stored in the pickle file. This allows you to generate
|
|
additional frames in a sequence without parsing the full ip log on each
|
|
run. For example, you can run this script daily, using ip client
|
|
information from the end of previous day stored in the pickle file.
|
|
Run in this manner, the script will generate 24 new frames daily using
|
|
only daily ip client logs for each day.
|
|
|
|
|
|
outdir defaults to ./animation-frames/
|
|
you must make sure outdir exists.
|
|
|
|
outdir holds:
|
|
the sequence of generated frame images with prefix frame_
|
|
the pickle file saved_data.pickle, which stores previous frame data
|
|
summary client_per_capita: clientpop_<epoch>.png
|
|
population density: population_<epoch>.png
|
|
summary of client density: current_<epoch>.png
|
|
|
|
<epoch> is the most recent epoch associate with a the script.
