nummu 0.1.2

An animated image maker.

nummu (南無)

An animated image maker.

NOTE: this project in WIP and thus interface might change a lot. Be cautious when using in production.

Usage

By extending Nummu, you might want to implement a class having these methods: init(), update(delta), draw(palette). None of them are absolutely required.

class HelloWorld:

    def init(self):
        # Do initial work here
        self.position = 0

    def update(self, delta):
        # Do some calculation before draw each frame.
        # The delta is in millisecond unit.
        #
        # Don't forget to raise StopIteration somewhere!
        #
        self.position += delta
        if self.position >= 100:
            raise StopIteration

    def draw(self, pallete):
        # Pallete is simply a numpy.zeros instance.
        # Overwrite any pixels as you want.
        #
        pallete[:, self.position, :] = 255

Basic usage:

# import nummu
from nummu import Nummu

# set file size
nm = Nummu(100, 100)

# extend nummu
nm.extend(HelloWorld())

# export to apng
nm.export('helloworld.png', delay=5)

Check the examples in project repo, and hopefully it might intrigue you some!
