__version__ = "1.0.3" # Major.Minor.Patch
|
|
|
|
# Ways to run this program:-
|
|
|
|
# 1. With ampy
|
|
# ampy --port $PORT run bin/photo.py
|
|
# example output:-
|
|
# photo fn=out.jpg size=22((default)) quality=10
|
|
# Length of buf: 23579
|
|
|
|
# 2. From REPL shell
|
|
# >>> ARGV=["pic.jpg","5","10"];exec(open("bin/photo.py").read())
|
|
# example output:-
|
|
# photo fn=pic.jpg size=5(FRAME_QVGA) quality=10
|
|
# Length of buf: 9495
|
|
|
|
# 3. using mipyshell
|
|
# To run this program with arguments, install https://github.com/vsolina/mipyshell
|
|
# and save this file as bin/photo.py - then (for size 5 and quality 10):-
|
|
# photo outfile.jpg 5 10
|
|
|
