g is just a reference to the same object. You need to create a copy to get a new object with the same content.

import copy

a = 1
b = [(a, a), (a + 1, a + 1)]
print(id(b))

g = b
print(id(g))

g = copy.deepcopy(b)
print(id(g))

small example to get you started!!

there are multiple formulas to ease in ease out..

def linear(factor):
    return factor

def easeIn(factor):
    return factor*factor

def easeOut(factor):
    return factor * (2-factor)


steps = 100

blockWidth = width() / steps


for func in [linear, easeIn, easeOut]:
    newPage()
    for i in range(steps):
        factor = i / (steps-1)
        factor = func(factor)
        rect(0, 0, blockWidth, height() * factor)    
        translate(blockWidth, 0)    

what does work:

im = ImageObject()

im.linearGradient((300, 300), (50, 0), (300, 0), color0=(1, 0, 0, 1), color1=(0, 1, 0, .3))

fontSize(100)
text("Hello World", (0, 30))

image(im, (0, 0))

This creates a image with a gradient with opacity. But it will be a lot slower...

you can set a frameDuration(seconds) for every frame. This will speed up if you keep the same amount of frames.

If you want to keep the same length of the animation you you have to use a combo of a higher frameDuration and a higher frame rate.

see http://www.drawbot.com/content/canvas/pages.html#drawBot.frameDuration

The documentation is adjusted and path.onCurvePoints and path.offCurvePoints and the path contours are immutable now.

closed points in a bezierPath must be a tuple as it is immutable #350

The attributes onCurvePoints of a bezierPath is a immutable representation of the path points.

I would like to encourage you to look at pens and how to alter point data and point structures while drawing in a pen.

A drawBot BezierPath is also a pen.

I only wanted to teach you how to narrow down the problem, by elimenating parts :), make the problem as small as possible and fix the smallest problems first.

All the Glyhps callback are not the issue:

When you draw physically: you would start a drawing by first taking some paper, picking up a pencil, put the pencil down and draw, finish the drawing by framing it and hanging it on the wall!

Translating your code: you are drawing on the same paper over and over again, and only saving the image after you hang it to the wall...

I will let you try some more

good luck!!
