Hi Maurice, expandStroke() returns a path.

Almost the same code, but instead of drawing a grid we draw 1000 circles randomly. As they have to stay in the same place, we save their locations in an array.

(Also in this script some nice code to have if you want to publish animated gifs; a way to reduce the colours in the gif.)

Hi Maurice, expandStroke() returns a path.

Thanks. Sorry, should have tried instead of thinking an omision in the documentation meant the functionality wasn't there.

It’s possible to change the value of a bool by selecting and Cmd-clicking.

Is it possible to also make this work with a key combination? I find myself using Cmd and the arrow keys to change values of variables a lot. Using the same keys, just to toggle a bool, would be useful to me.

nFrames = 60

for n in range(nFrames):
    newPage(480, 270)

    with savedState():
        fill(0,1,0)
        # move origin of the canvas to the center
        translate(width()/2, height()/2)
        # rotate the canvas
        rotate(-360 * n/nFrames)
        # move the origin again 
        translate(radius, 0)
        rect(-50, -50, 100, 100)

        fill(1,0,1)

        rotate(-360 * n/nFrames)
        translate(radius, 0)
        # counter-rotate the canvas so the rect appears to not rotate
        rotate(360 * n/nFrames)
        rect(-50, -50, 100, 100)

Maybe check out savedState(). Translate and rotate affect the whole canvas, wrapping separate objects in savedState() makes it easier to keep track what is happening.

Can you use listdir to get all file names and then open them one by one?

# This should return a list of all items on the desktop.
import os
# Change your_account_name to your account name 
print(os.listdir('/Users/your_account_name/Desktop/'))

One way of doing this is increasing the font size until it no longer fits the rectangle.

# Based on the examples on https://www.drawbot.com/content/text/drawingText.html

fs = 1
txt = "hello"
box = (100, 300, 800, 400)

fontSize(fs)
# Increasing the fontsize fs until the text no longer fits.
# textOverflow returns the overflowed text without drawing the text.
while textOverflow("hello", box) == "":
    fs += 1
    fontSize(fs)

# The fontsize adds up until the text no longer fits. To make the text fit, fs must be 1 smaller.
fontSize(fs-1)
# Draw a red box in the background
fill(1, 0, 0)
rect(*box)
# Draw white text over the box
fill(1)
textBox(txt, box, align="center")

Not wrapping the pdf in an ImageObject() will keep the vectors.

@jo Shouldn’t it be the other way around, though?

y, x = divmod(i, 8)

@jo There’s so much I don’t know. Thanks for the tip.
