Utility to create motion graphics with Python scripts. It uses Wand to generate images.
main.py [options] <script> [-o <output>]scriptis a Python script to use.-o <output>specifies output directory. It has to be a printf-style string with single number input for frame. By default it renders to./render/%03d.pngrelative to working directory.
--props=<value>JSON encoded properties for graphics. If script declares a schema input will be validated against it.
Scripts define how animation's state is changing and how it should be
rendered. It's represented with a class inherited from Graphics.
Graphics subclasses can contain their data as any other class.
Properties are stored in props attribute by default.
State should be initialized in a constructor for the first frame.
Class may define a update(delta) method which is then called every
frame with the delta time that equals to 1 / FPS.
draw() function is required. It creates an image for the current
frame after init() or update() is called.
Class must be passed as a first positional paramater of register().
By default sequence longs 1 frame and accepts any props.
register() parameters allows to adjust it. To define an animation
you need to specify both duration (in seconds) and fps. Schema
is a Python Schema which
validates the provided properties before execution.
